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.
