Introduction to Diagnosis

INTRODUCTION TO DIAGNOSIS

TPMS MAY NOT WORK NORMALLY IN THE FOLLOWING CIRCUMSTANCES
- A wireless facility or device using the same frequency with the TPMS transmitter is near the vehicle.
- Snow or ice is stuck inside the fenders and /or on the wheels.
- The TPMS transmitter's battery is discharged.
- Wheels other than Mitsubishi genuine wheels are being used.
- Wheels that are not fitted with TPMS transmitters are being used.
- Wheels whose tire pressure sensor IDs are not registered by the vehicle are being used.

TIRE PRESSURE MONITORING SYSTEM (TPMS) DIAGNOSIS

WHEN THE TPMS WARNING LIGHT IS ON
- If the TPMS warning light illuminates, check the inflation pressure of all the tires and adjust if necessary. If the TPMS warning light still remains illuminated, a flat tire or a defective TPMS transmitter is suspected.
- If a road tire does not contain a TPMS transmitter, the TPMS warning light will flash and the TPMS will not work normally. Replace the tire with one containing a TPMS transmitter.

AFTER REPLACING TPMS COMPONENTS
- Whenever the TPMS transmitter and/or TPMS receiver are replaced, register the tire pressure sensor ID of all the TPMS transmitter-contained tires.
- Whenever any TPMS component (transmitter and receiver) is removed and installed, confirm that no TPMS DTC is set.
