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 remote control door lock receiver (RCDLR) 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 RCDLR has undergone the tire pressure sensor learn procedure and 1 ignition cycle has occurred.
Diagnostic Aids
A newly replaced RCDLR will set DTC C0775 on its initial ignition ON cycle. The tire pressure sensor learn procedure must be performed.
