Diagnostic Test

CHECK FOR AN ACTIVE DTC
NOTE:
This fault can be set if the spare tire is currently installed on the vehicle, and it is not equipped with a TPM Sensor.
1. Check for and remove any non-FCC compliant components.
2. Verify that all tire pressures are to the recommended cold inflation tire pressure specifications.
3. Turn the ignition on.
4. With the scan tool, read DTCs and record on the repair order.
5. Test drive the vehicle at a speed greater than 24 km/h (15 mph) up to 20 minutes in order to receive TPM Sensor data and allow for the system to update.
6. With the scan tool, erase DTCs.
7. With the scan tool, read TPM DTCs.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Test complete. The condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
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 Defective
  - Tire 1 Rotation Detection HW Defective
  - Tire 1 Loss of Sensor Signal
  - Tire 1 Missing Sensor ID
  - Tire 1 Duplicate Sensor ID
  Do any of the above faults read "Set"?
  
  Yes
  - Go To 3
  No
  - Perform the INTERMITTENT DTC PROCEDURE. Refer to TESTING FOR AN INTERMITTENT CONDITION .
CHECK FOR CORRECT TIRE PRESSURE MONITORING (TPM) SENSOR
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.
  NOTE:
  Use a TPM-RKE Analyzer Tool to scan each TPM Sensor for a response. If you receive no response from any of the TPM Sensors, check to make sure that the TPM-RKE Analyzer is set correctly for that Model Year and Vehicle Line Code and repeat the process on each non-responsive wheel. If no response replace the sensor
  
  Is the correct TPM Sensor installed on the vehicle?
  
  Yes
  - Go To 4
  No
  - Install the correct Tire Pressure Monitoring (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 .
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 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 . Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
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
  - Install the Tire Pressure Monitoring (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 .
  No
  - Go To 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
  - Replace the Tire Pressure Monitoring (TPM) Module in accordance with the Service Information. Refer to MODULE, TIRE PRESSURE MONITORING (TPM), REMOVAL .
  - Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete.
  - Perform the TPM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
