Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system. NOTE: Seasonal temperature changes will affect tire pressure, and may have caused the tire pressure to fall below the low pressure warning threshold. Tire pressure should always be set based on cold inflation tire pressure (placard). This is defined as the tire pressure after a vehicle has not been driven for more then 3 hours, and in outside ambient temperatures. Correct all tire pressure to the recommended specifications and wait 2 minutes. With the scan tool, clear DTCs in the Wireless Control Module (WCM).

2. TIRE PRESSURE MONITORING (TPM) SENSOR NOTE: The following tests are used to locate the Tire Pressure Monitoring (TPM) Sensor/Transmitter that is setting the sensor internal fault. If the tires have been rotated, the Tire Pressure Monitoring (TPM) Sensor/Transmitter are no longer in sequence from the factory. Faults are linked to the sensor/transmitter IDs. You MUST locate the correct Tire Pressure Monitoring (TPM) Sensor/Transmitter that set the fault before continuing. Use one or more of the following methods below. METHOD 1: Use a TPM-RKE Analyzer tool to scan each tire pressure sensor. If a suspected sensor has been located, lower the tire pressure to 20 PSI, wait for 2 minutes, and check the scan tool for changes to any compensated tire pressure values. If there was a pressure change to any compensated tire pressure values, check to make sure that the TPM-RKE Analyzer is set correctly, and repeat the process on each wheel on the vehicle until the faulty Sensor/Transmitter has been identified. On base systems starting with the left front wheel, deflate the tire to 20 PSI, wait 2 minutes, and check the scan tool for changes to any compensated tire pressure values or TPM lamp turning on. Look for NO pressure change to any compensated tire pressure value, or a pressure change corresponding to "Sensor 1 Identification". NOTE: Compensated tire pressure values are only available on the premium TPM system. For a base TPM system lowering the tire pressure to 20 PSI will set DTC C0077 and turn on the TPM lamp. NOTE: When scanning a sensor with a TPM-RKE Analyzer, replace the TPM sensor if the results show a "Damaged Accel", "Damaged Temp", or "Damaged Press". Has the malfunctioning/faulty TPM sensor been located? Yes Replace the Tire Pressure Monitoring (TPM) Sensor Refer to «STANDARD PROCEDURE»(ref-485546-S13917643862012071300000) and perform the TPM VERIFICATION TEST. No Go To 3 .

4. INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR DTC NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WCM (WCM) fault. Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system. The conditions necessary to set this DTC are not present at this time. Refer to any Technical Service Bulletins that may apply to this condition. With the scan tool, clear DTCs in the Wireless Control Module (WCM). Test Drive the vehicle for a minimum of 10 minutes with vehicle speed greater than 15 m.p.h. With the scan tool, select View DTCs in the Wireless Control Module (WCM).
