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 tyre pressure sensor IDs are not registered by the vehicle are being used.
  • Compact spare tyre is fitted on a road wheel.
  • A window tint that affects the radio wave signals is installed.

WHEN THE TPMS WARNING LAMP IS ON



  • If the TPMS warning lamp illuminates, check the inflation pressure of all the tyres and adjust and drive if necessary. If the TPMS warning lamp still remains illuminated, a flat tyre or a defective TPMS transmitter is suspected.
  • If a road tyre does not contain a TPMS transmitter, the TPMS warning lamp will flash* and the TPMS will not work normally. Replace the tyre with one containing a TPMS transmitter.
    note *: Flash for approximately 1 minute and then remain illuminated.

AFTER REPLACING TPMS COMPONENTS



  • Whenever the TPMS transmitter and/or ETACS-ECU are replaced, register the tyre pressure sensor ID of all the TPMS transmitter-contained tyres.
  • Whenever any TPMS component (transmitter and ETACS-ECU) is removed and installed, confirm that no TPMS diagnosis code is set.
