Diagnostic Test
- READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR DTC TO RETURN
- With the scan tool, read DTCs in all Electronic Control Units (ECUs) and record on the repair order.
- For future reference, with the scan tool, run and save a vehicle Scan Report and all related recorded data.
- With the scan tool, erase all DTCs.
- Turn the ignition off for a minimum of 10.0 seconds.
- Turn the ignition on.
- Using the When Monitored and Set Conditions above and recorded data, operate the vehicle in the conditions that set the DTC.
- With the scan tool, read DTCs.
Did the DTC return?
Yes
- Go to 2
No
- Perform the "Intermittent DTC Procedure" Refer to STANDARD PROCEDURE - INTERMITTENT DTC PROCEDURE .
- USE THE TPM-RKE ANALYZER TO VERIFY THE CORRECT TPM SENSOR IS INSTALLED ON THE VEHICLE NOTE:
This fault can be set if the incorrect or no TPM Sensor is installed on the vehicle. If the spare tire is currently installed on the vehicle, and it is not equipped with a TPM Sensor, this DTC can be set. Replace the spare with a TPM Sensor equipped wheel and tire assembly. Test drive the vehicle. If the DTC resets, continue with the diagnostic procedure.
- Perform a visual inspection to verify that all road wheels are equipped with a TPM Sensor.
- With the TPM-RKE Analyzer (special tool #2046300080, Kit, TPM/RKE ANALYZER) verify the correct TPM Sensor is on the vehicle.
Is the correct TPM Sensor installed on the vehicle?
Yes
- Go To 3
No
- Install the correct Tire Pressure Monitoring (TPM) Sensor in accordance with the Service Information. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), REMOVAL AND INSTALLATION .
- Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE - TPM VERIFICATION .
- USE THE TPM-RKE ANALYZER TO LOCATE THE TIRE PRESSURE MONITORING (TPM) SENSOR WITH AN INTERNAL FAULT NOTE:
The following procedure is used to locate the TPM Sensor that is setting the internal fault. If the tires have been rotated, the TPM Sensor is no longer in sequence from the factory. Faults are linked to the TPM Sensor IDs. You MUST locate the TPM Sensor that set the fault before continuing. Use the following method below at every tire location.
NOTE:If the TPM Sensor IDs do not match, it may be necessary to move the vehicle to a location away from other TPM Sensors and repeat this step.
NOTE:Always be certain to select the proper vehicle line and model year when using this tool, as the tool will automatically use the correct protocol to attempt to read the TPM Sensor. If the incorrect vehicle line and/or model year is selected, the TPM Sensor will not respond to the tool.
- Use a TPM-RKE Analyzer (special tool #2046300080, Kit, TPM/RKE ANALYZER) to scan each TPM Sensor for a response, and store in the proper location in the TPM-RKE Analyzer. If you receive no response from any of the TPM Sensors, check to make sure that the TPM-RKE Analyzer is set correctly and repeat the process on each non-responsive wheel.
- Replace the TPM Sensor if the results show a "Damaged Accel", "Damaged Temp", "Damaged Press", "H/W fail", "S/W fail" or the TPM Sensor does not respond after repeated attempts. Install the correct Tire Pressure Monitoring (TPM) Sensor in accordance with the Service Information. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), REMOVAL AND INSTALLATION . Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
- With the scan tool, select Data Display for the TPM Module.
- Check to see if the Sensor IDs match what is programmed into the TPM Module.
Has the TPM Sensor been located?
Yes
- Install the correct Tire Pressure Monitoring (TPM) Sensor in accordance with the Service Information. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), REMOVAL AND INSTALLATION .
- Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE - TPM VERIFICATION .
No
- Go To 4
- USE TPM-RKE ANALYZER TO FIND TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT FOR MISMATCHED ID NOTE:
If the TPM Sensor IDs do not match, it may be necessary to move the vehicle to a location away from other TPM Sensors and repeat this step.
- Use a TPM-RKE Analyzer (special tool #2046300080, Kit, TPM/RKE ANALYZER) to verify the TPM Sensor IDs match what is programmed into the TPM Module. The TPM Sensor Identifications are located under "Data Display" for the TPM Module.
Do the TPM Sensor IDs match what is stored in the TPM Module?
Yes
- Install a new Tire Pressure Monitoring (TPM) Module in accordance with the Service Information. Refer to MODULE, TIRE PRESSURE MONITORING (TPM), REMOVAL AND INSTALLATION .
- Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE - TPM VERIFICATION .
No
- Test complete.
- Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE - TPM VERIFICATION .
