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 It is a legacy product that has been superseded by the Autel AutoLink AL301¹. 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. ^_^¹ 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
Question:	Will this work on a Nissan X trail T
Answer:	yes, I'm using Windows Phone 8 on Nokia 920 with OBDAutoDoctor application. You need to connect the PIC18F2480 via Bluetooth, before starting an OBD2 scan tool application. On Windows Phone 8 only a few OBD2 app are available. OBDAutoDoctor is free but get only some information from the car. 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.

On-Board Monitor Test

Troubleshooter functions: These give you a set of recommended fixes for problems detected by the scanner. This feature is tricky to score, since the advice given is only valuable if the diagnosis is precise enough to pinpoint a specific problem.

Evap test: This is a specific mode 8 command that tells your car to start a test of the “evaporative emission control system” (mechanics call it “evap” for short) that prevents fuel from evaporating out of your tank and contributing to smog. Triggering this test won’t fix anything by itself, but once you do fix a problem with the fuel system it’s nice to be able to manually trigger a test. This way you can verify your fix right away, without waiting a few days (or longer) for your car to run it automatically.

I/M READINESS

To know if you are ready for a smog check, press I/M button(rubber) for 3 seconds.

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
