Autel MaxiLink ML629 New Generation OBDII Code Reader for Vehicle Engine/Transmission/AirBag/Brake System (Supports all 10Modes OBD2 Test)

1. ABS: An anti-lock braking system is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than many drivers could manage.
2. SRS: The purpose of the SRS light on your instrument panel is to alert you of a potential problem with your supplemental restraint system.
3. Engine: The “Malfunction Indicator Lamp” (or Check Engine Light) is supposed to come on when a problem occurs in the engine control system that affects emission. Depending on how the system is configured and the nature of the problem, the lamp may come on and go off, remain on continuously or flash. When this happens, the OBDII system sets one or more diagnostic trouble codes that correspond to the problem detected. ML629 is the scan tool that can help you read and clear codes for engine control system.
4. Transmission: This scan tool supports reading DTCs and data stream of the transmission for knowing the reason for the warning light and keep the Transmission system healthy.

• Full OBDII DIAGNOSTICS:

1. Read Codes: The Read Codes function can be performed with the Key On Engine Off (KOEO) or with the Key On Engine Running (KOER). [including Stored Codes, Pending Codes, Permanent Codes]
2. Erase Codes: Erasing the Diagnostic Trouble Codes may allow the scan tool to delete not only the codes from the vehicle’s on-board computer, but also “Freeze Frame” data and manufacturer-specific enhanced data. Further, the I/M Readiness Monitor Status for all vehicle monitors is reset to Not Ready or Not Complete status. Do not erase the codes before repairs or services have been performed.
3. Live Data: The View Data function allows viewing of live or real time PID data of vehicle’s computer module(s).
4. View Freeze Frame Data: Freeze Frame Data allows the technician to view the vehicle’s operating parameters at the moment a DTC (Diagnostic Trouble Code) is detected.
5. Retrieve I/M Readiness Status: I/M Readiness function is used to check the operations of the Emission System on OBDII compliant vehicles.
6. O2 Monitor Test: OBDII regulations set by the (Society of Automotive Engineers) SAE require vehicles monitors and tests on the oxygen (O2) sensors to identify problems related to fuel efficiency and vehicle emissions.
7. On-Board Monitor Test: The On-Board Monitor Test for CAN-Equipped vehicles retrieves and displays test results for Emission-Related power train components and systems that are and are not continuously monitored.
8. Component Test: The Component Test initiates a leak test for the Vehicle's EVAP system.
9. View Vehicle Information: The Vehicle Info. function enables retrieval of Vehicle Identification No.(VIN), Calibration ID Nos. (CINs), Calibration Verification Nos. (CVNs) and In-use Performance Tracking on 2000 and newer vehicles that support Mode9.
10. Modules Present: The Modules Present function displays the Module IDs and communication protocols for OBDII Modules in the vehicle.

No matter where you are, let this gadget accompanies with you. Let you decide if it's something you can fix or need more advanced help. Save money and time.

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:	Funciona para un Aveo
Answer:	No se
Question:	Why I can't erase the fault code
Answer:	Thank you for your question. 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. A fault code which provide a jumping off point in the diagnostic process. Then probably the vehicle still has a an issue. Codes only erase if the problem is repaired.
Question:	How can update os601? when do i need to upgrade it
Answer:	Contact the seller for an upgrade package. The upgrade is free. Anytime
Question:	How do you upgrade the software once it is out of date
Answer:	Thank you for your question. In most cases, the upgrade is to fix bugs in the software. In general, a six-month upgrade is sufficient (Because the support for the OBD-II protocol is stable). For other situations of upgrade or diagnosis, you can collect the corresponding model information and send it to us to provide more services. 【How to upgrade?】Connect scan tool with PC through Mini B connector(5 pin) at the bottom of the machine, migrate the upgrade data into it. For more detailed information, please email us via the station and we will send you the upgrade file. May you have a nice day! Warm Regards, Juta Auto

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.

I/M readiness is to test Misfire / Fuel system / Comprehensive component. Quickly monitor emissions readiness check and drive cycle verification. Let you know the comprehensive status of your car's engine system. Help you pass the Smog Check easily.
