Case Number: S2508000026
Release Date: April 2025
Symptom/Vehicle Issue: Tire Pressure Lamp Flashing, No Tire Pressures Displayed, “Tire
Pressure Module (TPM) System Unavailable” Message Displayed on Cluster

Customer Complaint/Technician Observation: Owner complains or complains of one or
more of the above. Technician observed the vehicle has a TPM lamp on and a Diagnostic Trouble
Code (DTC) C151D-00 Tire Pressure Sensor Location Undetermined.

Discussion: When the localization sequence does not complete a total of 10 times consecutively f
the localization DTC C151D-00 is set. This DTC can be removed without replacing the Radio
Frequency Hub (RFH) by following below instructions.
To remove this DTC, TPMS relearning or reprogramming need to be done instead of replacing the
RFH.
The below steps need to be followed for relearning or reprogramming TPMS:
Step 1: Use the latest version of TPM-RKE Analyzer tool to do this activity
Step 2: With the scan Tool, record all 4 Sensor IDs from the RFH memory
Step 3: With the TPM-RKE Analyzer Tool at the most recent version, select the specific vehicle line
and model year. NOTE: If the incorrect vehicle line or model year are selected the TPM sensor
may not respond to the TPM-RKE Analyzer Tool.
Step 4: With the TPM-RKE Analyzer Tool, read all the TPM Sensors on the vehicle, record their IDs,
wheel positions, and operation state (the TPM Sensors should be in the PARK mode). If a sensor
doesn’t read the first time, try several more times. NOTE: There is a remote possibility the TPMRKE Analyzer Tool can read a TPM Sensor from a different vehicle, instead of the vehicle
being tested. If a sensor ID read by the TPM-RKE Analyzer Tool does not match any of the IDs
in the RF Hub recorded earlier, relocate vehicles to a proximity that is greater than 10 feet and
repeat reading.

Now perform Localization test as shown below:
1. • With the scan tool, write false IDs into each of the sensor locations in the RF Hub as follows:
Sensor 1 = 11111111, Sensor 2 = 22222222, Sensor 3 = 33333333, Sensor 4 = 44444444). This
will cause the TPM display pressure values to go to dashes on the TPM display of the Cluster.
• Using the sensor IDs recorded earlier with the TPM RKE Analyzer tool, write the sensor IDs
into the RFH one position clockwise more than the actual position (i.e. the Sensor ID at FL is
written into the RFH FR (sensor 1) position: Sensor ID at FR written into RR.…). Programming the
IDs will set the C151D-00 DTC to stored.
