Tire Pressure Monitoring System Control Module
The Radio Frequency (RF) receiver is integrated into the Tire Pressure Monitoring System Control Module (TPMSCM), which is mounted on headliner next to overhead console and connects to the vehicle harness via a four pin plug.
The TPMSCM receives transmissions from each of the tire pressure sensors via an internal antenna in each of the sensors. This information is then decoded and analyzed and any required warnings along with current tire pressure information is communicated on the High Speed (HS) Controller Area Network (CAN).
