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.

DTC STATUS IS ACTIVE
NOTE:
Before beginning the diagnostic procedure, check for and remove any non-FCC compliant components before beginning this 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.
1. Cycle the ignition on.
2. With the scan tool, read and record the RF-Hub Module DTCs.
3. With the scan tool, erase stored RF-Hub Module DTCs.
4. Drive the vehicle at speeds greater than 32 km/h (20 mph) for 10 minutes.
5. With the scan tool, read DTCs in the RF-Hub Module.
  Is this DTC Active at this time?
  
  Yes
  - Go To 2
  No
  - Go To 4
TIRE PRESSURE MONITORING (TPM) WINTER MODE
NOTE:
Repair all other RF -Hub Module DTCs before continuing with this test procedure.
1. Cycle the ignition off.
2. Cycle the ignition from off to on.
3. Check for the following conditions:
  - The telltale lamp is off.
  - The tire pressure values in the Instrument Cluster are displayed as dashes.
  - The message center is not displaying "SERVICE TPM SYSTEM".
  Are all of the above conditions correct?
  
  Yes
  - The Radio Frequency Hub (RF Hub) Module is now in deactivation mode (Winter Mode). This DTC will remain active until the correct tire and wheel assemblies are installed back on the vehicle. Once one of the correct tire and wheel assemblies are reinstalled, the other three must also be reinstalled prior to turning the ignition on.
  No
  - Go To 3
TIRE PRESSURE MONITORING (TPM) SENSORS
1. Cycle the ignition off.
2. Verify the correct TPM Sensors are installed in all of the tire and wheel assemblies.
  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)
3. 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.
  Are the correct TPM Sensors installed?
  
  Yes
  - Replace the Radio Frequency (RF Hub) Module in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL .
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST .
  No
  - Install all new Tire Pressure Monitoring (TPM) Sensors in accordance with the Service Information. Refer to SENSOR, TIRE PRESSURE MONITORING (TPM), REMOVAL .
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
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 10 minutes with vehicle speed greater than 32 km/h (20 mph).
5. With the scan tool, read DTCs in the Radio Frequency Hub (RF-Hub) Module.
  Does the DTC reset or is the status Active for this DTC?
  
  Yes
  - 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 .
  No
  - Test complete.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to TPM SENSOR VERIFICATION TEST .
