14 best obd scan tools

OBD (On-Board Diagnostics) scan tools are essential devices used in the automotive industry for diagnosing and troubleshooting issues with vehicles. They play a crucial role in identifying and interpreting the diagnostic trouble codes (DTCs) generated by a vehicle's onboard computer system. Here are some key points about OBD scan tools:

  1. Purpose: OBD scan tools are primarily used to read and clear diagnostic trouble codes (DTCs) generated by a vehicle's onboard computer system. These codes indicate specific issues or malfunctions within the vehicle's various systems, including the engine, transmission, emissions, and more.

  2. Compatibility: OBD scan tools are designed to be compatible with the OBD-II (On-Board Diagnostics 2) standard, which is a standardized system used in most vehicles manufactured since the mid-1990s. Some older vehicles may use OBD-I, which requires specialized scan tools.

  3. Functionality: OBD scan tools come in various forms, ranging from basic code readers to more advanced diagnostic tools. Basic code readers can retrieve and display DTCs, while more advanced scan tools can provide additional information, such as live data streaming, freeze frame data, and real-time sensor readings.

  4. Diagnosis: When a vehicle's check engine light (MIL - Malfunction Indicator Lamp) illuminates, an OBD scan tool can be connected to the vehicle's OBD-II port (usually located under the dashboard near the steering column) to retrieve the relevant DTCs. These codes can help mechanics and vehicle owners pinpoint the specific problem areas within the vehicle.

  5. Clearing Codes: In addition to reading DTCs, OBD scan tools can also clear or reset the codes after the issue has been resolved. This is often necessary to turn off the check engine light.

  6. Maintenance and Repairs: OBD scan tools are valuable tools for mechanics and DIY enthusiasts, as they assist in diagnosing problems quickly and accurately, reducing the guesswork involved in vehicle maintenance and repairs. They can help prevent further damage and ensure the vehicle runs efficiently.

  7. Variety: There is a wide range of OBD scan tools available on the market, from handheld devices to smartphone apps that connect to an OBD-II adapter via Bluetooth or Wi-Fi.The choice of scan tool depends on the user's needs and preferences.

  8. Professional vs. Consumer Grade: Some OBD scan tools are designed for professional mechanics and offer advanced features, while others are more user-friendly for consumers and may provide simplified diagnostics.

Overall, OBD scan tools are indispensable for anyone involved in vehicle maintenance, from professional mechanics and technicians to car owners who want to understand and address issues with their vehicles. These tools empower individuals to identify and resolve automotive problems efficiently, potentially saving time and money on repairs.

Where's the OBDII interface?

It is often under the dash, or under a panel below the handbrake in the center console.

What is OBD-II?

On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. Vehicles produced after 1996 use OBD-II, which is a standardized system that simplifies the process a whole lot. These vehicles all use a common diagnostic connector and a set of universal trouble codes. Though only emission-related codes and data are required to be transmitted through it according to U.S. legislation, most manufacturers have made the OBD-II Data Link Connector the main connector in the vehicle through which all systems are diagnosed and reprogrammed.

At the most basic level, the check engine light indicates that some sensor, somewhere in your engine, exhaust, or transmission, has provided unexpected data to computer. That could indicate a problem with the system the sensor is responsible for monitoring, a bad sensor, or even a wiring issue.

Why I can't erase the fault code?

Once the monitors are reset, the MIL will either remain out because the DTC was corrected by the proper repair, or it will illuminate because it has again detected the problem.

  • Universal Compatibility: Applicable to MOST US-based cars (made in 1996 or later), EU-based cars (made in 2001 or later), Asian cars (made in 2008 or later), and all OBD II/EOBD/CAN-compliant vehicles.
  • Smog Check: Clearly shows whether the emission-related systems are operating properly or ready for inspection and maintenance testing; turns off check engine light and resets monitors; views freeze frame data, read live PCM data stream, EVAP system test data, On-Board Monitor test data and display live O2 sensor test data.
  • Shows the code and what the code means directly. Able to retrieve generic (PO P2 P3 and UO) manufacturer specific (P1, P3, and U1) codes and pending codes, and vehicle information (VIN, CID and CVN). And can store the data you have viewed (DTCs, freeze Frame, live data, etc).
  • Supports all OBDII protocols, including ISO9141, KWP2000, J1850 PWM, J1850 VPW and CAN (Controller Area Network).
  • No battery needed, just plug it into the OBDII port and start diagnosis. Features a 2.5-foot flexible plug and a 7-button panel. Supports DTC look-up, and software upgrade. Supports multi-language display (English, German, Spanish, Dutch, Russian).

User questions & answers

Question: Will it read ABS codes
Answer: I do not know...if you have a security light flashing I would go to an Auto Zone they will do a free scan to tell you what is wrong with it and if it can be fixed or you may have to go to a dealership to have it fixed ....
Question: Does this work with Windows Phone
Answer: The Maxiscan MS300 is also an Autel product. It is a legacy product that has been superseded by the Autel AutoLink AL301š. As is customary for these entry-level devices, it only reads / reports the generic OBD II codes. To move up to manufacturer specific codes one must move up to the Autel AutoLink AL319². Keep in mind that not ALL manufacturer specific codes are possible to read / report on. Some are kept secret by the vehicle manufacturer to ensure the dealer techs get a shot at your wallet once in a while. ^_^š http://www.auteltech.com/autelcms/Code%20Readers&Code%20Scanners/357.jhtml² http://www.auteltech.com/autelcms/Code%20Readers&Code%20Scanners/358.jhtml
Question: can i leave it plugged in
Answer: Yes.It has an I/M Readiness mode that is able to show you the details of the readiness of each major emission monitor. There is even a button on the device that can select this directly without having to navigate through the menus.There is also a lamp on the device that indicates if any emission monitor is not ready.It is my understanding that the requirements for I/M readiness for each vehicle may differ from state to state.I had a problem with an air monitor coming ready after I identified, resolved, and cleared the underlying code. It took miles of specific type of driving to clear this monitor status (which cannot be cleared by the device.)When I returned to the inspection station I was informed that all monitors are not required to be ready to pass New York state inspection, and that my extra driving for this situation was unnecessary.
Question: does it pick up abs codes
Answer: It gives a text explanation of the code (eg. Nissan code P1135 = 'Intake Valve Timing Control Bank 2'). Beyond that, you're having to look online or in service manuals to determine what the message actually means and how to resolve it.

User questions & answers

Question: will this work on my 2000 Toyota Prado dieselwith 1KZ engine
Answer: Hi there, I am with BAFX Products. Sadly it will not read any ABS/SRS?VSC or any other codes. The only codes it is able to read are those which cause your vehicles "check engine" light to illuminate. Any other lights require more specialized tools for reading. Best regards, BAFX Products

I just found how to unlock the pro version...It's a in-app purchase...click "..." at the bottom of the app to upgrade. The Pro version is available for $7.99.
Question: i used this tool and all is said was manufacturer control. no code number with it? what does that mean? 1998 ford explorer sport
Answer: Hi Christopher - I am with BAFX Products Support.In MOST vehicles you will be ok leaving the adapter plugged in as long as the vehicle is driven every few days. However we make the following recommendations:1) Do not leave the adapter plugged in if it will not be driven for 24-48 hours2) If your area is to be experiencing extreme cold unplug the adapter as the combination of cold and the adapter will drain it faster3) If your battery is more than a 1-2 years old you will want to be very careful about leaving it plugged in, older batteries do not hold the same juice as the newer ones4) If you have an electronics heavy vehicle such as BMWs tend to be we do not recommend leaving it plugged in as the vehicles electronics do not always fully power down either5) If you have any other device plugged into the vehicle while it is off via cigarette ports or whatever we then also recommend removing the adapterI hope that these tips and information are found helpful. If you have any further questions you may always reach out to us through the Amazon messaging system at any time!Best regards,BAFX Products Support
Question: Can you use this to diagnosis why check engine light is on and figure out why car wont start? even of car wont start
Answer: I can confirm that this adapter WILL read (I haven't tried to clear yet) ABS codes on Ford (2001 Ranger 4.0L), using FordSysFree or MotorDataOBD Free (both Android). ABS codes are in the Cxxxx range. Mine picked up, correctly, C0034 - Front Right Wheel Speed Sensor Failure. While other adapters may be able to read these codes with other Android Apps, this ELM327 BAFX adapter does capture ABS codes for Ford. That is the only one I can confirm. Yes, FORScan for PC should also pick up these codes with this adapter. I have not tested Torque PRO, but I don't believe it will read ABS codes with this adapter.

This set of values is referred to as Freeze Frame Data and may include important engine parameters such as engine RPM, vehicle speed, mass airflow, engine load, fuel pressure, fuel trim value, engine coolant temperature, ignition timing advance, or closed loop status.

Smog Check

MS309 engine scanner code reader comes with I/M readiness status check function that shows you whether all the emission related systems and components are operating within allowable limits to help you pass the annual Smog Check.

The engine scanner shows readiness status with series of readiness monitors: continuous monitors like misfire, fuel system and comprehensive components monitor and non-continuous monitors like EGR system, O2 sensors, Catalyst, Evaporative System, O2 Sensor Heater, Secondary air, Heated Catalyst and A/C system.

DTC Definitions

Autel MS309 supprots DTC definitions. The definitons will be displayed bellow the codes. It provides you an easier way to read and a quick understanding of what's the meaning of the fault codes that was detected.No need to search online for what's the codes meaning.

Retrieve Vehicle Information

MS309 automotive scanner retrieves the Vehicle Identification No. (VIN), Calibration ID(s), Calibration Verification Nos. (CVNs). This function is especially useful while you take this little pocket OBD2 code reader with you while buying a used car to check whether the VIN matches and make sure the ECU has not been replaced with a garbage car.

User questions & answers

Question: Does this device/app seriously ask you for more money after you already bought it, in order to look up codes
Answer: No, it doesn't. I've owned Fixd since it came out; use it on three vehicles and have never been asked to pay for error code information. The error codes come with plain English explanations; in addition, Fixd tells you what level of seriousness the error code implies.
Question: Can Fixd clear trouble codes and reset the light
Answer: Yes! FIXD definitely lets you reset your check engine light. Once you scan your vehicle with the free FIXD App, you'll be able to see the codes present as well as a plain, English explanation then you'll also have the ability to clear your light.

Question: Does it work with an iPhone
Answer: The SmartPhone app (FREE download & no additional fees) works on Android or IOS (Apple iPhone) operating systems, but NOT on Windows based devices at present.
Question: Has anybody bought this who already owned a code reader. Did it provide any additional useful info
Answer: No. Without the subscription you can only read and turn off your check engine light that's it. I don't know what turning off your check engine light is suppose to do for you because the problem is still there until you get it fixed. Paying a monthly or yearly subscription is insane. Remember this is only a Bluetooth interface between your car and your phone. You can always download another app from the app store, that's what I did. I downloaded an app called car scanner ELM OBD2 and it works just great and it's completely free. There are a lot to choose from at the app store. When you're trying to get it connected it will ask you for some kind of password or something which normally is either 0000 or 1234, I forgot which one of those I used.

OBD II Modes of Operation:

Here is a basic introduction to the OBD II communication protocol. Mode byte: The first byte in the stream is the mode number. There are 10 modes for diagnostic requests. The first byte in the response data bytes is this same number plus 64. For example, a mode 1 request would have the first data byte = 1, and the response would have the first data byte = 65. Here is a brief description of the modes:

  • Mode 01 – Identifies the Powertrain information and shows current data available to the scan tool. This data includes: DTC set, status of on-board tests, and vehicle data such as engine RPM, temperatures, ignition advance, speed, air flow rates, and closed loop status for fuel system.
  • Mode 02 – Displays Freeze Frame data. Same data as in mode 1,but it was captured and stored when a malfunction occurred and a DTC was set. Some of the PIDs for mode one are not implemented in this mode.
  • Mode 03 – Displays the type of powertrain or emission related DTCs stored by a 5 digit code identifying the faults. There may be more than one response message if there are more trouble codes than will fit in the data bytes of the response message, or if there are more than one ECU computer responding.
  • Mode 04 – Used to clear DTCs and Freeze Frame data. This clears all diagnostic trouble codes that may be set including freeze frame data and readiness monitors.
  • Mode 05 – Displays oxygen sensor test results. This mode displays the oxygen sensor monitor screen and the test results gathered about the oxygen sensor. There are ten numbers available for diagnostics: 01) Rich-to-Lean O2 sensor threshold voltage. 02) Lean-to-Rich O2 sensor threshold voltage. 03) Low sensor voltage threshold for switch time measurement. 04) High sensor voltage threshold for switch time measurement. 05) Rich-to-Lean switch time in ms. 06) Lean-to-Rich switch time in ms. 07) Minimum voltage for test. 08) Maximum voltage for test. 09) Time between voltage transitions in ms.
  • Mode 06 – Non-continuously Monitored Systems test results.There are typically a minimum value, a maximum value, and a current value for each non-continuous monitor. This data is optional, and it is defined by a given vehicle maker if it’s used.
  • Mode 07 – A request for DTCs (pending) from Continuously Monitored Systems after a single driving cycle has been performed to determine if repair has fixed a problem. This is used by service technicians to verify repair was performed properly and after clearing diagnostic trouble codes.
  • Mode 08 – This special Control Mode requests control of the on-board system, test, or component bi-directionally (where applicable). This mode is manufacturer specific.
  • Mode 09 – Reports vehicle information. This information includes vehicle VIN number and calibration information stored in the vehicle ECUs.
  • Mode 0A – Requests Emission-Related Diagnostic Trouble Codes with Permanent Status. This mode is required for all emissions-related DTCs.The presence of permanent DTCs at an inspection without the MIL illuminated is an indication that a proper repair was not verified by the on-board monitoring system.

When more than one vehicle control module is detected by the scan tool, you will be prompted to select the module where the data may be retrieved. The most often to be selected are the Power train Control Module [PCM] and Transmission Control Module [TCM].

CAUTION: Don’t connect or disconnect any test equipment with ignition on or engine running.

  1. Turn the ignition off.
  2. Locate the vehicle’s 16-pin Data Link Connector (DLC).
  3. Plug the scan tool cable connector into the vehicle’s DLC.
  4. Turn the ignition on. Engine can be off or running.
  5. Turn on the scan tool. Use the "UP/DOWN" scroll button to select OBDII/EOBD from the Main Screen.
  6. Press the "OK" button to wait for the Menu to appear. A sequence of messages displaying the OBDII protocols will be observed on the display until the vehicle protocol is detected.
  7. View a summary of system status (MIL status, DTC counts, Monitor status) on screen. Press [OK]

If the scan tool fails to communicate with the vehicle’s ECU (Engine Control Unit) more than three times, a “LINKING ERROR!” message shows up on the display.

  • Verify that the ignition is ON;
  • Check if the scan tool’s OBD II connector is securely connected to the vehicle’s DLC;
  • Verify that the vehicle is OBD II compliant;
  • Turn the ignition off and wait for about 10 seconds. Turn the ignition back to on and repeat the procedure.

If the “LINKING ERROR” message does not go away, then there might be problems for the scan tool to communicate with the vehicle. Contact your local distributor or the manufacturer’s Customer--Service department for assistance.

I/M Ready Test & I/M Readiness Hot Key:

The Ready Test can be used as a convenient readiness test tool by automotive technicians to determine if the tested vehicle is ready for an emission test. By visual and audible indication,you will learn a vehicle’s monitors readiness. Repairs to the emissions-control systems of a 1996 or newer vehicle cause the vehicle’s computer (ECU) memory to be cleared. The vehicle must go through a drive cycle to allow the ECU to perform a series of tests to ensure that the repair was successful, and before a state mandated emissions test can be conducted. But how will you know when it is ready? With this scan tool, you don’t have to drive around endlessly and continuously coming back to the repair shop for retest if all required tests by the ECU are completed. And you could also do a quick check of the vehicle to determine if it is ready to receive an emission test without the hassle of connecting your vehicle to the analyzer or having to use a complicated scan tool.In the following cases, this function is especially useful.

  • You bought a used car and the check engine light had been cleared to mask potential problems.
  • You disconnected the battery for tune-ups and other engine repairs, dead battery replacement, car radio installation and car alarm installation.
  • You used a scan tool to clear the DTCs.
  • Your car has been sent to repair.

I/M refers to Inspection and Maintenance that is legislated by the Government to meet federal clean-air standards. I/M Readiness indicates whether or not the various emissions-related systems on the vehicle are operating properly and are ready for Inspection and Maintenance testing.

The purpose of the I/M Readiness Monitor Status is to indicate which of the vehicle’s Monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle’s emissions system.

The I/M Readiness Monitor Status function also can be used (after repair of a fault has been performed) to confirm that the repair has been performed correctly, and/or to check for Monitor Run Status.

Note: N/A means not available on this vehicle; INC means incomplete or not ready and OK means Completed or Monitor Ok.

CHECK ENGINE LIGHT:

Quickly and accurately to read the engine fault code, built-in DTC look up library to show the DTC definitions,make it easy to determine the cause of the Check Engine Light(MIL), and turn off Check Engine Light by erasing the trouble codes and Monitors reset.

Battery Monitor: NL101 could quickly check the vehicle’s battery health, read out the current battery value and give out 6 levels of warnings for your knowledge:

  • A. <10.8V(before Starting): Too Low; Change your battery, otherwise, might not be able to start;
  • B. 10.8V-11.8V(before starting): Slightly low; Difficult to start, please turn off other electronics and start vehicle to charge;
  • C. 11.8V-12.8V(before starting): Normal;
  • D. 12.8V-13.2V(after starting): Too Low; Might not be able to charge the battery, please check other electrical load;
  • E. 13.2V-14.8V(after starting): Normal;
  • F. >14.8V: Too High; Might damage the battery, please check the engine stabilizer.

Power Supply: The power of the NL101 is provided via the vehicle’s Data Link Connector (DLC). Follow the steps below to power it up:

  1. Find DLC on the Vehicle: The DLC is the connector where diagnostic code readers interface with the vehicle’s on-board computer and usually located in the driver’s cab. A plastic DLC cover may be found for some vehicles and you need to remove it before plugging the OBD II cable. If it cannot be found, refer to the vehicle’s service manual for the location.
  2. Plug OBD II cable to the vehicle’s DLC.

One Click "Help" for Data Stream & View Freeze Frame:

  • This item enables you to view all data stream items and the live waveform of all selected items.Some data stream have the help information ,press the [?] .
  • When an emission-related fault occurs, certain vehicle conditions are recorded by the on-board computer. This information is referred to as freeze frame data. Freeze Data is a snapshot of the operating conditions at the time of an emission-related fault.

Note: If DTCs were erased, Freeze Data may not be stored in vehicle memory depending on vehicle.

Location of the Data Link Connector (DLC): The DLC (Data Link Connector) is the standardized 16-cavity connector where diagnostic scan tools interface with the vehicle's on-board computer. The DLC is usually located 12 inches from the center of the instrument panel (dash), under or around the driver side for most vehicles. If Data Link Connector is not located under dashboard, a label should be there telling location. For some Asian and European vehicles, the DLC is located behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the vehicle service manual for the location.

Package Accessories:

  • Main Unit with OBD 16PIN Diagnostic Cable

OBDLink MX+, Bluetooth OBD2 Scanner and Vehicle Performance Monitor

This pocket-size adapter won't obstruct driver legroom and features unmatched performance, intelligent sleep mode, hacker-proof security, exceptional third party app support, and free lifetime firmware and software updates.

The free OBDLink app offers outstanding features that makes it easy to access, graph, log and export real-time engine data. Plus, your car's data can be directly downloaded or instantaneously uploaded and shared with others using DropBox.

OBDLink MX+ provides wireless connectivity for all OBD-II protocols, plus advanced automotive networks commonly used in many late-model GM, Ford, Mazda, Nissan and Toyota vehicles. For supported GM models, you can control windows, door locks, and even remotely start your engine with the 3rd-party obdCANex Android app.

More Coverage

OBDLink MX+ works with all 1996 and newer cars and light trucks sold in the United States (except hybrid or electric vehicles). The OBDLink proprietary connection algorithm enables MX+ to connect to more makes and models than any other scan tool. It also supports EOBD, JOBD, and all other international variants of OBD-II. Read and clear codes on all OBD-compliant vehicles, NO EXCEPTIONS.

More Features

OBDLink MX+'s functionality is limited only by the imagination of the programmers that write the apps. Apps that exist on the market today, can be used to:

  • Measure and display fuel economy
  • Remote start your car (on select vehicles)
  • Create a digital dashboard or a heads-up display
  • Buy a used car with confidence
  • Lock/unlock doors (on select vehicles)
  • Clear the ‘Check Engine’ light, and investigate its cause
  • Display, graph, and log hundreds of real-time parameters

More Secure

Unlike other OBD adapters, MX+ does not use an easy-to-guess PIN and requires physical access for the initial pairing. It doesn't broadcast its presence and employs strong encryption — sensible precautions to keep hackers out of your vehicle's network.

More Apps

OBDLink MX+ works with dozens of popular third-party apps like Torque, Dash, FORScan, DashCommand, obdCANex and Harry's Lap Timer to unlock enhanced performance, save fuel, change vehicle settings and even control door locks and remotely start the engine on select vehicles.

More Data

With third party apps, you can enable convenience features (including remote start and door lock/unlock) and change configuration on select models.

More Reliable

When you turn off your engine, OBDLink MX+ goes to sleep and won't drain your automobile's battery. Its sophisticated triggers will wake up MX+ when you connect via Bluetooth, unlock doors, or crank the engine.

MX+ includes overvoltage/load dump protection, a feature critical for any OBD device that is designed to be powered from the vehicle's 12-volt system.
