Diagnostic Test

  1. CHECK FOR AN ACTIVE DTC 
    NOTE:

    Before beginning diagnostic procedure, verify that the tire pressures are correct.

    1. Turn the ignition on.
    2. With the scan tool, read TPM Module DTCs and record on the repair order.
    3. With the scan tool, erase TPM Module DTCs.
    4. Test drive the vehicle at a speed greater than 20 km/h (13 mph) up to 20 minutes in order to receive TPM Sensor data and allow for the system to update.
    5. With the scan tool, read TPM Module DTCs.

      Did the DTC return?

      Yes 

      • Go to 2

      No 

      • Go to 7
  2. TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT ACTIVE 
    1. Turn the ignition on.
    2. With the scan tool, select Data Display for the TPM Module and locate the following:
      • Tire 1 Pressure Sensor HW Fault
      • Tire 1 Pressure Sensor Missing ID
      • Tire 1 Temperature Sensor HW Fault
      • Tire 1 Temperature Sensor SW O/U
      • Tire 1 Acceleration Sensor HW Fault
      • Tire 1 Loss of Signal from Pressure Sensor

      Do any of the above faults read "Set"?

      Yes 

      • Go to 3

      No 

      • Go to 6
  3. TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL DTC 
    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.

    1. Perform a visual inspection to verify that all road wheels are equipped with a TPM Sensor.
    2. 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 4

      No 

  4. TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT SET USING TPM-RKE ANALYZER 
    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.

    1. 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.
    2. Replace the TPM Sensor in accordance with the Service Information. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), REMOVAL . Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE - TPM VERIFICATION  .
    3. With the scan tool, select Data Display for the TPM Module.
    4. Check to see if the Sensor IDs match what is programmed into the TPM Module.

      Has the TPM Sensor been located?

      Yes 

      No 

      • Go to 5
  5. TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT - 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.

    1. 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 

      No 

  6. TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT SET 
    NOTE:

    Some vehicles will not receive the TPM Sensor data when the vehicle is stationary. The vehicle may need to be driven at speeds greater than 20 km/h (13 mph) for about a minute in order to receive TPM Sensor data.

    1. Starting with the left front wheel, deflate the tire to 20 PSI, wait two minutes, and check the scan tool for changes to any compensated tire pressure values.
    2. Look for a tire location with a non-responsive TPM Sensor ID.
    3. Repeat this test on each wheel on the vehicle until the TPM Sensor in question has been identified.

      Has the TPM Sensor been located?

      Yes 

      No 

  7. INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR DTC 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Perform any Service Bulletins that may apply to this condition.
    3. With the scan tool, erase TPM Module DTCs.
    4. Test drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 20 km/h (13 mph).
    5. With the scan tool, read TPM Module DTCs.

      Did the DTC return?

      Yes 

      • Return to the beginning of this test and perform the diagnostic procedure as necessary.

      No
