S2522000003 Service Bulletin/Repair Instructions

Case Number: S2522000003

Release Date: October 2025

Symptom/Vehicle Issue: Tire Pressure Monitor (TPM) Warning Lamp On Or Flashing.

Sensor(s) Not Reading And Or Showing Dashes.

Discussion: Vehicles with tire warning lamp on or missing tire pressure complaints,

with or without DTCs, should be visually inspected for OEM and non-OEM equipment

to ensure the proper tire location programming. Use the Ateq TPM Tool to relearn any

OEM or non-OEM tires sensors to ensure compatibility and learning for proper

operation before any component replacement. Review the below information for tips

that may help root cause and repair TPM conditions.

General checks:

* Verify that the 12V Vehicle battery is good, as low or dead batteries may cause TPM

to not function as designed.

* Check for and perform any applicable radio frequency hub (RFH) and instrument

panel control (IPC) service bulletin software updates.

* Disconnect the remote start antenna coaxial cable, wait for a minute and plug it back

in and verify if the antenna is working as expected, as any issues with it can cause

TPM and fob issues.

* Inspect the remote start antenna wiring for pinches or damages, as any of these can

cause issues with the TPM and the fob functions.

* Verify the programmed tire placard values match the recommended tire pressure

values in case of any TPM concern.

* If an RFH is replaced for any other concern, please program the TPMS sensor IDs

into the new RFH and perform the autolearn procedure (road driving to self learn).
TPM sensor specific instructions:

1. Perform a visual inspection of the vehicle including tire and wheel condition.

Address any physical damage to wheel/tire assemblies first including severely

cupped and or damaged tires.

2. Perform diagnostics for any DTCs

3. To verify the sensor is functional and without damage, use the ATEQ TPM tool to

check – sensor ID, tire pressure, battery status, etc.

4. Check the TPMS sensor locations manually with the ATEQ tool and verify if the

positions programmed in the RFHM match the sensor locations on the tool. If not,

perform the step-by-step TPMS auto learn procedure.

5. If there are any issues with tire pressure (observed on cluster and ATEQ), inflate

or deflate to the required PSI (placard pressure). Incorrect inflation can also

delay sensor learning.

6. If there are loose or improperly installed sensors (observed in step e), repair as

required.

7. If there are any issues with sensor such as low battery (observed in step a),

physical damages (observed in step e), replace the sensor. Dead/bad sensors

will not allow the system to update and learn during a test drive (autolearn).
 TPM sensors will go into a low power sleep state if the tire(s) have been

stationary for a long time before rotation, the sensor may need motion to fully wake up

and transmit data.

TPM Autolearn after tire rotation or service work:

1. Tire Rotation Completed: Rotate the tires as needed.

2. Key ON / Engine Start: After rotation, cycle the ignition to RUN (engine ON).

3. Drive the vehicle at speeds above 15 mph (24 km/h) continuously for about 10–15

minutes. (Some systems may take up to 20 minutes.)

4. During the Drive the TPM module listens for RF signals from each tire sensor. It

measures pressure, temperature, and wheel speed correlation from ABS. It matches

sensor IDs to the new tire positions based on signal strength and wheel speed.

5. If Autolearn was successful, the TPM module updates the internal learned positions

automatically. TPM warning lights should be off after learning. You can verify learned

positions using WiTECH and viewing TPM sensor data in the RFH.

6. If TPMS Light Stays ON:

• Ensure tire pressures are correct (match the placard).

• Drive more time if needed.

• If light remains ON after 20–30 minutes of driving, check for a stored TPMS DTC

or low battery sensors.
