DTC Descriptor
DTC C0774 00
- Low Tire Pressure System Performance
Circuit Description
The electronic brake control module (EBCM) receives a serial data message from the tire pressure monitor (TPM) system when low tire pressure is
detected. The EBCM will adjust the responses of vehicle stability enhancement system (VSES) to have optimal vehicle control when active.
Conditions for Running the DTC
* Vehicle speed is 32 km/h (20 mph), or greater for 1 minute.
* VSES is active.
Conditions for Setting the DTC
The EBCM receives a serial data message of low tire pressure is detected.
Actions Taken When the DTC Sets
* The EBCM adjusts the VSES responses to compensate for a low tire pressure condition to maintain optimal control of the vehicle.
* No warning indicators and/or messages will be displayed.
Conditions for Clearing the DTC
* A current DTC will clear when the TPM system is reset.
* A history DTC will clear after 100 consecutive malfunction-free ignition cycles from when the TPM system has been reset.
