TPMS Inspection Method

Inspection

1. 1
   Types of Warning Lights

   • Remains on without flashing: Tire Pressure Low Indicator
   • Flashes continuously at 0.5 second intervals: Indicator initial state
   • Instrument cluster flashes for 1 minute at 1 second intervals, then stays on: DTC indicator
2. 2
   (1) Check the indicator status.

   • Check the vehicle lighting condition.
   • Check whether the lighting condition is caused by low tire pressure.

     

     Symptom: Stays on without flashing
3. 3
   (2) Check the indicator status.

   • Check the vehicle lighting condition.
   • Check whether the lamp condition is caused by the initial state of the TPMS receiver (empty mode).

     

     Symptom: Flashes continuously at 0.5 second intervals.
4. 4
   (3) Check the indicator status.

   • Check the vehicle lighting condition.
   • Check whether the indicator condition is caused by a DTC (TPMS sensor and TPMS receiver malfunction). Symptom: Instrument cluster flashes for 1 minute at 1 second intervals, then illuminates.
5. 5
   Tire Pressure Warning Lamp Cold: Vehicle has been stopped for more than 60 minutes. → 0.07 kgf/cm² (1.0 psi) additional inflation beyond specified tire pressure. Hot: Drive the vehicle. → 0.28 kgf/cm² (4.0 psi) additional inflation beyond specified tire pressure.
6. 6
   Check the initial state indicator

   Q.	TPMS warning lamp (1) Check the status of the TPMS warning lamp. (2) Flashes continuously at 0.5 second intervals. → Initial state indicator

   B.	Items to check when the warning lamp flashes (1). Enter the sensor ID. (See TPMS Receiver – Repair Procedures) (2). Enter the vehicle name. (See TPMS Receiver – Repair Procedures) (3). Enter the VIN. (See TPMS Receiver – Repair Procedures) (4). Change the TPMS ECU mode (to standard mode).
