DTC Descriptor

DTC C0775 00: Tire Pressure Monitoring System Sensors Malfunction

Circuit/System Description

If the body control module (BCM) has been reprogrammed or replaced and the tire pressure sensor autolearn process has not occured, the tire pressure monitor system indicator icon on the instrument cluster will flash for 1 min. and then remain illuminated after the ignition switch is cycled ON and the instrument cluster bulb check is complete. If equipped, the driver information center will also display a service tire monitor type message. Under these circumstances, DTC C0775 will be set in the BCM and the tire pressure sensor autolearn process will need to be performed for the system to function correctly. The remote control door lock receiver receives and sends the tire pressure and temperature data to the body control module (BCM). The tire pressure indicator module receives and sends sensor ID and location data to the BCM. The tire pressure indicator module determines tire side to side position by the rotating direction of the tires and the front to rear position by the strength of the signals received. To complete the tire pressure indicator module autolearn process it is required that the vehicle be driven for at least 9 minutes above 40 km/h (25 MPH).

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

The body control module (BCM) has not received tire sensor ID and location information from the tire pressure indicator module.

Action Taken When the DTC Sets

•  The tire pressure monitor system indicator icon on the instrument cluster will flash for 1 min. and then remain illuminated after the ignition switch is cycled ON and the instrument cluster bulb check is complete.
•  If equipped, the driver information center displays a service tire monitor type warning message.

Conditions for Clearing the DTC

A current DTC will clear when the BCM has received tire sensor ID and location information from the tire pressure indicator module and at least 1 ignition cycle has occurred.
