Diagnostic Test

WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

VERIFY DTC 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:
FF is the default value. If this value is found, the Module has not been programmed.

NOTE:
Check for and remove any non-FCC compliant components before beginning this diagnostic procedure.
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/r (20 mph) for 20 minutes in order to receive TPM data and allow for the system to update.
4. With the scan tool, read DTCs in the Radio Frequency Hub (RF-Hub) Module.
  Is the DTC status Active at this time?
  
  Yes
  - Go To 2
  No
  - Test complete.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
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 IDS
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 (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/r (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
  - Test complete.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
  No
  - With the scan tool, read RF-Hub DTCs. If any displayed, perform the appropriate diagnostic procedure. If there are none, repeat this test. A bad RF-Hub will have other DTCs set.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
WITHOUT TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR IDS
1. Cycle 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/r (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
  - Test complete.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
  No
  - With the scan tool, read RF-Hub DTCs. If any displayed, perform the appropriate diagnostic procedure. If there are none, repeat this test. A bad RF-Hub will have other DTCs set.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
