DTC Descriptor
DTC C0775
- Low Tire Pressure System Sensors Not Learned

Diagnostic Fault Information

Perform the Diagnostic System Check - Tire Pressure Monitoring prior to using this diagnostic procedure. Diagnostic System Check - Tire Pressure Monitoring

Circuit/System Description

The remote control door lock receiver (RCDLR) receives a radio frequency (RF) transmission from each tire pressure sensor. Each sensors RF transmission contains its own unique identification (ID) code that must be learned into the RCDLR memory. Once all 4 IDs have been learned and vehicle speed is 25 mph or greater, the RCDLR continuously compares IDs in received transmission to its learned IDs to determine if all 4 sensors are present.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

The RCDLR has not undergone the tire pressure sensor learn procedure.

Action Taken When the DTC Sets

The driver information center (DIC) displays the SERVICE TIRE MONITOR warning message.
Conditions for Clearing the DTC

A current DTC will clear when the RCDLR has undergone the sensor learn procedure.

Diagnostic Aids

A newly replaced RCDLR will set DTC C0775 on its initial ignition ON cycle. Tire pressure sensor learn procedure must be performed.
