Inspection and Verification

Tire Pressure Monitoring System

Inspection and Verification

NOTE: The tire pressure sensors are not designed to be used with aftermarket wheels.

NOTE: The use of run-flat tires (tires with steel body cord plies in the tire sidewall) or rigid sidewall tires (19.5" steel carcass heavy-duty tires) where not originally equipped, may cause the Tire Pressure Monitoring System (TPMS) to malfunction and are not recommended.

NOTE: Swapping wheels between vehicles with the same TPMS causes a TPMS fault to be set if the sensors are not trained. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Tire Pressure Monitoring System (TPMS) Sensor Training.

NOTE: The valve-mounted TPMS sensors and the strap-mounted TPMS sensors are not compatible. Swapping wheels from one vehicle to another with the different systems sets a TPMS fault.

NOTE: Non-OEM modifications made to the vehicle may result in false TPMS warnings.

1. Verify the customer concern by observing the TPMS warning indicator and the message center.

2. Visually inspect for obvious signs of mechanical or electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

4. NOTE: Make sure to use the latest scan tool software release.

If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).

5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.

If the scan tool does not communicate with the VCM:

- check the VCM connection to the vehicle.

- check the scan tool connection to the VCM.

- refer to Module Communications Network Testing and Inspection, No Power To The Scan Tool, to diagnose no power to the scan tool.

6. If the scan tool does not communicate with the vehicle:
- verify the ignition key is in the ON position.

- verify the scan tool operation with a known good vehicle.

- refer to Module Communications Network Testing and Inspection, The PCM Does Not Respond To the Scan Tool, to diagnose no response from the PCM.

7. Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to Module Communications Network Testing and Inspection.

- If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble Codes (CMDTCs).

8. Clear the CMDTCs and carry out the self-test diagnostics for the BCM and the TPM module.

9. If the DTCs retrieved are related to the concern, go to the Body Control Module (BCM) DTC Chart Body Control Module (BCM) DTC Chart or the TPM Module DTC Chart Tire Pressure Monitor (TPM) Module DTC Chart. For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in Multifunction Electronic Modules Multifunction Electronic Modules.

10. If no DTCs related to the concern are retrieved, GO to Symptom Chart. Symptom Related Diagnostic Procedures
