DTC Descriptor
DTC C0775 00
- Low Tire Pressure System Sensors Malfunction

Circuit/System Description

If the tire pressure sensor learn procedure has not been performed, the tire pressure monitor indicator icon on the instrument panel cluster (IPC) will flash for 1 minute and then remain illuminated after the ignition switch is cycled ON and the IPC bulb check is complete. If equipped, the driver information center (DIC) will also display a service tire monitor type message. Under these circumstances, DTC C0775 will be set and the tire pressure sensor learn procedure will need to be performed for the system to function correctly.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

The body control module (BCM) has not undergone the tire pressure sensor learn procedure.

Action Taken When the DTC Sets

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

Conditions for Clearing the DTC

A current DTC will clear when the BCM has undergone the tire pressure sensor learn procedure and 1 ignition cycle has occurred.
