Tire Pressure Monitoring System (TPMS) Module

The SJB  contains the TPMS  functionality. Refer to TIRE PRESSURE MONITORING SYSTEM  in Diagnosis and Testing for TPMS  fault diagnosis and repair.

The SJB  compares the information of each tire pressure sensor transmission against a pressure limit. If the SJB  determines that the tire pressure has fallen below the low limit, the SJB  communicates this to the IC on the vehicle communication bus.
