Pinpoint Test E: Smart Junction Box (SJB) Will Not Enter Sensor Training Mode When Using the Tire Pressure Monitoring System (TPMS) Sensor Training Procedure
Normal Operation
For the Smart Junction Box (SJB) to enter Tire Pressure Monitoring System (TPMS) sensor training mode, the SJB must receive valid inputs from the Brake Pedal Position (BPP) switch (OFF-ON-OFF) and ignition switch (both OFF and RUN), and it must receive valid vehicle speed sensor input (0 km/h [0 mph]). Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Programming and Relearning for the complete sensor training procedure.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Brake ON/OFF switch
- Ignition switch
- SJB
