C151C
C151C-TIRE PRESSURE MONITORING (TPM) SENSORS MISSING
For a complete wiring diagram, refer to the Wiring Information.
Theory of Operation
When installing a new Wireless Ignition Node (WIN), the module is programed with universal IDs for the Tire Pressure Monitoring (TPM) Sensors. The WIN must be programmed with the correct TPM Sensor IDs.
- When Monitored:
During vehicle TPM Sensor ID locate process.
- Set Condition:
When installing a new Wireless Ignition Node (WIN).
1. VERIFY DTC IS ACTIVE
NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WIN fault. Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.
1. Correct all tire pressures to the recommended cold inflation tire pressure specifications and wait two minutes for the system to update.
2. Ignition on, engine not running.
3. With the scan tool, record and erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for a minimum of 10 minutes in order to receive TPM data and allow for the system to update.
5. With the scan tool, read DTCs.
Is the DTC status Active at this time?
Yes
- Go To 2
No
- Go To 5
2. TPM-RKE ANALYZER 9936
Is there a TPM-RKE Analyzer 9936 available?
Yes
- Go To 3
No
- Go To 4
3. WITH TPM-RKE ANALYZER 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 9936 to scan each TPM Sensor for an ID, store in the proper location in the TPM-RKE Analyzer.
2. Use a TPM-RKE Analyzer 9936 to upload the correct IDs and proper locations in the scan tool.
3. With the scan tool, select the TIPM Module under "Miscellaneous Functions", follow the procedure for uploading TPM Sensor IDs.
4. With the scan tool, erase DTCs.
5. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for a minimum of 10 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 Module IDs match what is programmed into the WIN.
Do the TPM IDs match?
Yes
- Test complete.
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.
No
- Install a new Wireless Ignition Node (WIN).
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.
4. WITHOUT TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR ID(S)
1. 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.
2. Repeat the above step on each wheel of the vehicle.
3. With the scan tool, erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for a minimum of 10 minutes in order to receive TPM data and allow for the system to update.
5. With the scan tool, check to see if the TPM IDs are programmed into the WIN.
Are the TPM Sensor IDs in the WIN?
Yes
- Test complete.
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.
No
- Install a new Wireless Ignition Node (WIN).
- Perform the WIN VERIFICATION TEST. Wireless Ignition Node (WIN) Verification Test.
5. INTERMITTENT TIRE PRESSURE SENSOR DTC
NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WIN fault. Interference from other elements will over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.
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, erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for a minimum of 10 minutes in order to receive TPM data and allow for the system to update.
5. With the scan tool, read DTCs.
Does the DTC reset or is the status Active for this DTC?
Yes
- Go To 2
No
- Test complete.
