No, the Autel MaxiLink ML619 cannot be used to clear the TPMS (Tire Pressure Monitoring System) light. It is designed to read and clear codes related to the engine (MIL), ABS, and SRS systems, but there is no mention of TPMS functionality.

  • Page 5: General Information

    General Information On-Board Diagnostics (OBD) II The first generation of On-Board Diagnostics (called OBD I) was developed by the California Air Resources Board (ARB) and implemented in 1988 to monitor some of the emission control components on vehicles. As technology evolved and the desire to improve the On-Board Diagnostic system increased, a new generation of On-Board Diagnostic system was developed.
  • Page 6 Figure 1-1 Location of the Data Link Connector (DLC) The DLC (Data Link Connector or Diagnostic 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’s side for most vehicles.
  • Page 7 OBD II Readiness Monitors An important part of a vehicle’s OBD II system is the Readiness Monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system. They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits.

  • Page 8: Tatus

    The following monitors are to be used for compression ignition engines only: EGR System NMHC Catalyst NOx Aftertreatment Boost Pressure System Exhaust Gas Sensor PM Filter OBD II Monitor Readiness Status OBD II systems must indicate whether or not the vehicle’s PCM’s monitor system has completed testing on each component.
  • Page 9 OBD II Definitions Powertrain Control Module (PCM) – OBD II terminology for the on-board computer that controls engine and drive train. Malfunction Indicator Light (MIL) – Malfunction Indicator Light (Service Engine Soon, Check Engine) is a term used for the light on the instrument panel.

    Figure 2-8 Vehicle Coverage The MaxiLink ML619 OBDII/EOBD Scanner is specially designed to work with all OBD II compliant vehicles, including those equipped with the Control Area Network (CAN) protocol. The EPA requires all domestic, Asian and European vehicles, 1996 and newer (including light trucks), sold in the United States must be OBD II compliant.

  • Page 19: Product Troubleshooting

    Government regulations mandate that all OBD II compliant vehicles must have a “common” sixteen-pin Data Link Connector (DLC). For your vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission Control Information Label must state that the vehicle is OBD II compliant.
