Pinpoint Test F: The Driver Door Module (DDM) Will Not Enter Training Mode

Normal Operation

For the driver door module (DDM) to enter tire pressure monitoring system (TPMS) sensor training mode, it must receive valid inputs from the following:
^ Brake pedal position switch - OFF-ON-OFF
^ Ignition switch - both OFF and RUN
^ Vehicle speed sensor - 0 km/h (0 mph)

Refer to Tire Pressure Monitoring System (TPMS) Sensor Training for the complete sensor training procedure. Tire Pressure Monitoring System (TPMS) Sensor Training

The brake pedal position (BPP) switch input is supplied to central junction box (CJB) fuse 28 (7.5A) along circuit 511 (LG) and then to the lighting control module (LCM) along circuit 1651 (WH/RD). The LCM then provides the BPP information to the DDM along the standard corporate protocol (SCP) communication bus.

The ignition switch input is supplied to the LCM from CJB fuse 26 (10A) along circuit 640 (RD/YE) and CJB fuse 5 (7.5A) along circuit 297 (BK/LG). The LCM then provides the ignition switch information to the DDM along the SCP communication bus. The vehicle speed input is supplied by the PCM to the instrument cluster along the high-speed controller area network (HS-CAN) bus, then from the instrument cluster to the DDM along the SCP communication bus.

This pinpoint test is intended to diagnose the following:
^ Fuse
^ Wiring, terminals or connectors
^ Ignition switch
^ Vehicle speed sensor (VSS)
^ BPP switch
^ PCM
^ DDM
