Diagnostic Test

WARNING: This page is about a different car, the 2014 RAM 3500 HD and 2014 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

DTC STATUS IS ACTIVE
NOTE:
Before beginning diagnostic procedure, verify that all the tire pressures are correct and compared to the placard pressure settings.

NOTE:
When checking all tire pressures, verify any tire leaks or damage have been repaired/replaced as needed.
1. Turn the ignition on.
2. With the scan tool, read and record the RF-Hub Module DTCs.
3. With the scan tool, erase the RF-Hub Module DTCs.
4. Test drive the vehicle at a speed greater than 32 km/h (20 mph) up to 20 minutes in order to receive TPM Sensor data and allow for the system to update.
5. With the scan tool, read the DTCs in the RF-Hub Module.
  Is this DTC status Active at this time?
  
  Yes
  - Go To 2
  No
  - Test Complete.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
TPM-RKE ANALYZER CH9936
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 #CH9936, Analyzer, TPM/RKE) 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. With the scan tool, select Data Display for the RF-Hub Module.
3. Check to see if the Sensor IDs match what is programmed into the RF-Hub Module.
  NOTE:
  Some vehicles will not receive the TPM Sensor data when the vehicle is stationary. The vehicle may need to be driven at speeds greater than 32 km/h (20 mph) for about a minute in order to receive TPM Sensor data.
  
  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 SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete. 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.
  - Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
