- Go to step 4
No
- Go to step 7
TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL DTC
NOTE:
This fault can be set if incorrect or no TPM sensor are installed on the vehicle. If the Spare Tire is currently installed on the vehicle, and it is not equipped with a Tire Pressure Monitoring (TPM) Sensor, this DTC can be set. Replace the spare with a TPM equipped wheel and tire assembly. Tests drive the vehicle. If the DTCs reset continue with the diagnostic procedure.
1. Perform a visual inspection to verify that all road wheels are equipped with sensors.
2. With the TPM-RKE Analyzer 9936 verify the correct TPM sensors are on the vehicle.
  Are the correct TPM sensors installed on the vehicle?
  
  Yes
  - Go to step 5
  No
  - Install the correct Tire Pressure Monitoring (TPM) Sensor(s) in accordance with the Service Information.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - 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 9936 to scan each tire pressure sensor for a response, and store in the proper location in the TPM-RKE Analyzer. If you receive no response from any of the tire pressure 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", or the Tire Pressure Monitoring (TPM) Sensor does not respond after repeated attempts. Install the correct Tire Pressure Monitoring (TPM) Sensor(s) in accordance with the Service Information. Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
3. With the scan tool, select Data Display for the WIN.
4. Check to see if the Sensor IDs match what is programmed into the WIN.
  Has the Tire Pressure Monitoring (TPM) Sensor been located?
  
  Yes
  - Install the correct Tire Pressure Monitoring (TPM) Sensor(s) in accordance with the Service Information.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
  No
  - Go to step 6
TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT - MISMATCHED ID
NOTE: If the 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 9936 to verify the Sensor IDs match what is programmed into the WIN. The Sensor Identifications are located under "Data Display" for the WIN
  Do the sensor IDs match what is stored in the WIN
  
  Yes
  - Go to step 8
  No
  - Test complete.
TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT SET
NOTE: Some vehicles will not receive TPM Sensor data when the vehicle is stationary. The vehicle may need to be driven at speeds greater than 24 km/h (15 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 whose sensor ID that is not responding.
3. Repeat this test on each wheel on the vehicle until the sensor in question has been identified
  Has the Tire Pressure Monitoring (TPM) Sensor been located?
  
  Yes
  - Install the correct Tire Pressure Monitoring (TPM) Sensor(s) in accordance with the Service Information.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
  No
  - Test complete.
TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT - REMOTE START ANTENNA
1. If the vehicle is equipped with factory installed remote start feature, check to make sure the antenna connector is properly connected to the WIN.
  Is the Remote Start Antenna properly connected to the WIN?
  
  Yes
  - Go to step 9
  No
  - Test complete.
TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT - INTERFERENCE FROM EXTERNAL COMPONENTS
NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WIN fault. Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.

NOTE: A system fault can occur by many scenarios, including the following: 1) Signal interference due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the TPM sensors. 2) Installing aftermarket window tinting that affects radio wave signals. 3) Accumulation of snow or ice around the wheels or wheel housings. 4) Using tire chains on the vehicle. 5) Using wheels/tires not equipped with TPM sensors. 6) Loss of communication with the trigger modules (DH) or tire pressure monitoring sensors.
1. Attempt to isolate the external component responsible for the RF interference.
  Has interfering external component been isolated?
  
  Yes
  - Repair as necessary.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure
  No
  - Replace the Wireless Ignition Node (WIN) in accordance with the Service Information.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .

5. With the scan tool, read DTCs.
  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
