C151C Tire Pressure Monitoring (TPM) Sensor Missing

C151C Tire Pressure Monitoring (TPM) Sensor Missing - When installing a new Wireless Control Module (WCM), the module is programmed with universal IDs for the tire pressure monitoring (TPM) sensors. The WCM must be programmed with the correct TPM sensor IDs.

C151C Tire Pressure Monitoring (TPM) Sensor Missing


When monitored C151C code is during vehicle TPM sensor IDs locate process, and set condition when installing a new Wireless Control Module (WCM).

Possible causes C151C code

  • Incorrect tire pressure monitoring (TPM) sensor IDs.
  • Tire pressure monitoring (TPM) sensor.
  • Wireless Control Module (WCM).

Diagnose DTC C151C Tire Pressure Monitoring (TPM) Sensor Missing


Step 1. Verify DTC is active

Note: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WCM 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.

Correct all tire pressures to the recommended cold inflation tire pressure specifications and wait two minutes for the system to update. Ignition on, engine not running. With the scan tool, record and erase DTCs. Test drive the vehicle at a speed greater than 15 mph (24 km/h) for 10 minutes in order to receive TPM data and allow for the system to update. With the scan tool, read DTCs.

Is the DTC status active at this time?

YES, go to step 2.
NO, go to step 5.

Step 2. TPM-RKE analyzer tool

Is there a TPM-RKE analyzer available?

YES, go to step 3.
NO, go to step 4.

Step 3. 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 automatically uses 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 pf the non-responsive wheels.

Use a TPM-RKE anlyzer to scan each TPM sensor for an ID, store in the proper location in the TPM-RKE analyzer. Use a TPM-RKE analyzer to upload the correct IDs and proper locations in the scan tool. With the scan tool, select the TIPM/BCM, under ''miscellaneous functions'' follow the procedure for uploading TPS sensor IDs. With the scan tool, erase DTCs. Test drive the vehicle at a speed greater than 15 mph (24 km/h) for 10 minutes in order to receive TPM data and allow for the system to update. With the scan tool, check to see if the TPM sensor IDs match what programmed into the WCM.

Do the TPM IDs match?

YES, test complete.
NO, install a new Wireless Control Module (WCM).
