TPMS System Description - System Diagram
The TPMS module is integrated into the VSA modulator-control unit. In order to control tire pressure monitoring, the TPMS module first receives inputs from the VSA system, which includes the wheel speed sensors, the lateral acceleration sensor, the yaw rate sensor, the hydraulic pressure sensor, the steering angle sensor, the PCM, and the gauge control module. Then, the TPMS module sends commands to the gauge control module through the VSA modulator-control unit and issues warnings to the driver.
