Summary
Tire Pressure Warning Lamp is on Steady, or Flashing
Case Number: S2408000002
Release Date: January 2024
Symptom/Vehicle Issue: Tire Pressure Warning Lamp is on Steady, or Flashing
Customer Complaint/Technician Observation: The owner complains that the tire pressure
lamp is on steady or flashing. The technician observed the tire pressure lamp is on steady. A flashing
Tire Pressure Lamp is a sign that the vehicle has set a Diagnostic Trouble Code (DTC).
Repair Procedure: Some common complaints:
Tire Pressure Warning Lamp steady - No DTC
Tire Pressure Module Sensor (TPMS) display no pressure - DTC present
Tire Pressure Warning Lamp flashing - DTC present
Reduced Key FOB range/performance – with or without DTCs
Steady tire pressure lamp requires inspecting the tire pressure levels; adjust as required no
parts required.
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 VT56 tester to relearn any OEM or non-OEM tires sensors to ensure
compatibility and learning for proper operation before any component replacement.
Vehicles that set any of the following DTCs and are equipped with remote start sales code
(XBM Remote Start) can have a poor antenna connection at the antenna or module causing
performance issues. Test the performance of the remote signal and its battery with the Ateq VT56
tester to ensure good signal strength indicating a good battery. Use the range at the vehicle to test
FOB to vehicle performance from the max distance to test its performance after confirming the FOB
and battery are good. This can aid to identify if a potential antenna or connection issue.
If antenna issue has not been identified by performance or inspection, use the Ateq VT56 to
relearn the tire sensors and follow the Service Library (SL) diagnostics as needed for the DTCs
present before further parts replacement .
