Diagnostic Test

WARNING: This page is about a different car, the 2019 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
  1. DTC STATUS IS ACTIVE 
    NOTE:

    Before beginning the diagnostic procedure, verify that the tire pressures are correct, the 9936 TPM-RKE analyzer is up to date and the correct application has been chosen on the tool.

    NOTE:

    Check for any external possible causes that may have cause an overheating condition of the sensors. A over heated sensor(s) will shut down and become non-responsive.

    1. Cycle the ignition on.
    2. With the scan tool, read and record RF-Hub Module DTCs.
    3. Test drive the vehicle at a speed greater than 32 km/h (20 mph) up to 20 minutes in order to receive TPM Sensor data and allow for the system to update.
    4. With the scan tool, read active DTCs in the RF-Hub Module.

      Is this DTC status Active at this time?

      Yes 

      • Go To  2

      No 

      • Go To  4
  2. 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.

      Were any non-responsive TPM sensors located?

      Yes 

      No 

      • Go To  3
  3. 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 32 km/h (20 mph) for about 20 minutes 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 non-responsive TPM Sensor been located?

      Yes 

      No 

  4. INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR DTC 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Perform any Technical Service Bulletins that may apply to this condition.
    3. With the scan tool, clear DTCs in the Radio Frequency Hub (RF-Hub) Module.
    4. Test drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 32 km/h (20 mph).
    5. With the scan tool, read active DTCs in the Radio Frequency Hub (RF-Hub) Module.

      Does the DTC reset or is the status Active for this DTC?

      Yes 

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

      No
