Diagnostic Test

CHECK FOR AN ACTIVE DTC
NOTE:
Before beginning diagnostic procedure, verify that tire pressures are correct.
1. Press the ignition on.
2. With the scan tool, create a Vehicle Scan Report and attach it to the repair order.
3. With the scan tool, erase DTCs.
4. With the scan tool, read RFHM DTCs.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
TPM-RKE ANALYZER CH9936
Is there a TPM-RKE Analyzer CH9936 available?

Yes
- Go To 3
No
- Go To 4
WITH TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR ID(S)
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 Sensor. If the incorrect vehicle line and/or model year is selected, the Sensor will not respond to the tool.

NOTE:
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 of the non-responsive wheel(s)
1. Use a TPM-RKE Analyzer at the most current version available(special tool #2046300080, Kit, TPM/RKE ANALYZER) to scan each TPM Sensor for an ID, store in the proper location in the TPM-RKE Analyzer.
2. Use a TPM-RKE Analyzer to upload the correct IDs and proper locations in the scan tool.
3. With the scan tool, select the RF Hub Module under "Miscellaneous Functions", follow the procedure for uploading TPM Sensor IDs.
4. With the scan tool, erase RF Hub Module DTCs.
5. Test drive the vehicle at a speed greater than 32 km/h (20 mph) for 20 minutes in order to receive TPM data and allow for the system to update.
6. With the scan tool, check to see if the TPM sensor IDs match what is programmed into the RF Hub Module.
  Do the TPM IDs match?
  
  Yes
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
  No
  - Replace the Radio Frequency Hub Module (RFHM) in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL AND INSTALLATION .
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
WITHOUT TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR ID(S)
1. Press the ignition on.
2. 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.
3. Repeat the above step on each wheel of the vehicle.
4. With the scan tool, erase RF Hub Module DTCs.
5. Test drive the vehicle at a speed greater than 32 km/h (20 mph) for 20 minutes in order to receive TPM data and allow for the system to update.
6. With the scan tool, check to see if the TPM sensor IDs are programmed into the RF Hub Module.
  Are the TPM Sensor IDs in the RF Hub Module?
  
  Yes
  - Perform the TESTING FOR AN INTERMITTENT CONDITION procedure. Refer to TESTING FOR AN INTERMITTENT CONDITION .
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
  No
  - Replace the Radio Frequency Hub Module (RFHM) in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL AND INSTALLATION .
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
