Diagnostic Information for Tire Pressure Monitoring (TPM) System - DTC C0760 and/or C0765

This bulletin is being revised to update model year and labor operation information. Please discard Corporate Bulletin Number 03-03-16-001 (Section 03 -- Suspension).

The Tire Pressure Monitoring (TPM) System may set DTC C0760 - Left Rear Tire Pressure Sensor Malfunction and/or C0765 - Right Rear Tire Pressure Sensor Malfunction. Due to a programming error, the DTC may not lead the technician to the correct location of the malfunctioning sensor.

There are three possible failure modes in which these DTCs can set.

To diagnose the Tire Pressure Monitoring System, the following steps should be taken:

Important: The Tire Pressure Sensor Learn Procedure must be performed every time a tire pressure sensor or the PDM is replaced or the tires are rotated.

1. Perform the Tire Pressure Sensor Learn Procedure. Refer to SI Document ID #1311203 to ensure the sensors have not been mislocated from a previous tire rotation. If a horn chirp is heard on all 4 sensors, proceed to step 3.
2. If a horn chirp did not sound while learning a sensor, replace that sensor and again perform the sensor learn procedure to learn the new sensor ID. If a horn chirp still does not sound, replace the PDM and perform the sensor learn procedure.
3. Clear the DTC.
4. Test drive the vehicle and view the "Right Rear Pressure Sensor Mode" and the "Left Rear Pressure Sensor Mode" data parameter on the Tech 2®. Verify that both Right Rear and/or Left Rear Pressure Sensor Modes change from "wake" to "drive" at or above 32 km/h (20 mph).
5. If the Right Rear and Left Rear Pressure Sensor Modes change from "wake" to "drive", the system is working properly. If the Right Rear and/or Left Rear Pressure Sensor Modes do not change as indicated in step 4, replace whichever rear sensor did not change.
