Circuit Description

The tire pressure monitor (TPM) system has 4 radio frequency (RF) transmitting pressure sensors inside each wheel/tire assembly. If a sensor detects a low tire pressure, the DIC will display the CHECK TIRE PRESSURE, and the Electronic Brake Control Module (EBCM) will receive a serial data message that a DTC C0774 has set. The Vehicle Stability Enhancement System (VSES) will compensate for the low tire pressure with a calibration change to low tire present. Review the TPM for diagnostics for C0774.
