Pinpoint Test B: TPMS Will Not Enter Sensor Training Mode

Test B1-B3:

CAUTION: The Flex Probe Kit must be used for all test connections. Use of standard multimeter probes may damage wiring terminals.

Normal Operation
With the ignition on, the TPMS module enters the training mode when a combination of inputs are received from the brake pedal position (BPP) switch and the ignition status switch (from the instrument cluster).

The BPP signal and ignition status signal are sent to the TPMS module on the CAN network.

Possible Causes
- Circuit 1050 (LG/VT) ignition power
- BPP switch
- Ignition status (from instrument cluster)
- CAN network
- TPMS module
