Diagnostic Test
- DTC STATUS 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.
- Cycle the ignition on.
- With the scan tool, read and record the RF-Hub Module DTCs.
- With the scan tool, erase the RF-Hub Module DTCs.
- 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.
- 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
- Go To 5
- 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.
- 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.
- Replace the 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 .
- With the scan tool, select Data Display for the RF-Hub Module.
- Check to see if the Sensor IDs match what is programmed into the RF-Hub Module.
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
- Go To 3
- TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT - MISMATCHED ID 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.
- Use a TPM-RKE Analyzer (special tool #CH9936, Analyzer, TPM/RKE) to verify the TPM Sensor IDs match what is programmed into the RF-Hub Module. The TPM Sensor Identifications are located under "Data Display" for the RF-Hub Module.
Do the TPM Sensor IDs match what is stored in the RF-Hub Module?
Yes
- Replace the Radio Frequency (RF Hub) Module in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL .
- Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
No
- Test complete.
- Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
- Use a TPM-RKE Analyzer (special tool #CH9936, Analyzer, TPM/RKE) to verify the TPM Sensor IDs match what is programmed into the RF-Hub Module. The TPM Sensor Identifications are located under "Data Display" for the RF-Hub Module.
- TIRE PRESSURE MONITORING (TPM) SENSOR INTERNAL FAULT SET 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 20 minutes in order to receive TPM Sensor data.
- 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.
- Look for a tire location with a non-responsive TPM Sensor ID.
- Repeat this test on each wheel on the vehicle until the TPM Sensor in question has been identified.
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.
- Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
- INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR DTC
- The conditions necessary to set this DTC are not present at this time.
- Perform any Technical Service Bulletins that may apply to this condition.
- With the scan tool, clear DTCs in the Radio Frequency Hub (RF-Hub) Module.
- Test drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 32 km/h (20 mph).
- With the scan tool, rear the DTCs in the Radio Frequency Hub (RF-Hub) Module.
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
- Test complete.
- Perform the TPM SENSOR VERIFICATION TEST. Refer to STANDARD PROCEDURE .
