Module, Tire Pressure Monitoring (TPM): Operation

The Tire Pressure Monitor (TPM) module is able to receive individual tire pressure and temperature information from the TPM sensors located inside the road wheels. The TPM module has a CAN network interface to connect it to the vehicle network and carry out the following functions:

• Receives and processes the radio frequency data signals from each TPM sensor located inside each wheel.
• Monitors the TPM sensor status.
• Carries out self test.
• Calculates information from TPM sensors to generate low pressure and malfunction warnings.
• Transmits and receives information and status messages to other modules, the instrument panel cluster (IPC) and body control module (BCM), on the CAN network.
• Carries out diagnostic functions.
