TIRE PRESSURE MONITORING SYSTEM (TPMS)

INTRODUCTION TO DIAGNOSIS

TPMS MAY NOT WORK NORMALLY IN
THE FOLLOWING CIRCUMSTANCES:
 A wireless facility or device using the same fre-
quency 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.
 Compact spare tire is fitted on a road wheel.
 A window tint that affects the radio wave signals
is installed.
WHEN THE TPMS WARNING LIGHT IS ON
 If the TPMS warning light illuminates, check the
inflation pressure of all the tires and adjust and
drive if necessary. If the TPMS warning light still
remains illuminated, a flat tire or a defective
TPMS transmitter is suspected.

TPMS TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If
you follow them thoroughly, you will be sure that you
have exhausted most of the possible ways to find a
TPMS fault.
1. Gather information about the problem from the
customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any TPMS DTC.

TIRE PRESSURE MONITORING SYSTEM (TPMS) DIAGNOSIS

DIAGNOSIS
TSB Revision
 If a road tire does not contain a TPMS transmitter,
the TPMS warning light will flash
will not work normally. Replace the tire with one
containing a TPMS transmitter.
*
NOTE: : Flash for about 1 minute and then
remain illuminated.
AFTER REPLACING TPMS
COMPONENTS
 Whenever the TPMS transmitter and/or
ETACS-ECU <vehicles without Keyless Opera-
tion System> or KOS&OSS-ECU <vehicles with
Keyless Operation System> are replaced, regis-
ter the tire pressure sensor ID of all the TPMS
transmitter-contained tires.
 Whenever any TPMS component (transmitter
and ETACS-ECU <vehicles without Keyless
Operation System> or KOS&OSS-ECU <vehicles
with Keyless Operation System>) is removed and
installed, confirm that no TPMS DTC is set.
4. If you cannot verify the condition and there are no
TPMS DTCs, the malfunction is intermittent. Refer
to GROUP 00, How to Use
Troubleshooting/Inspection Service Points  How
to Cope with Intermittent Malfunctions P.00-13.
5. If there is a TPMS DTC, record the number of the
DTC, then perform the TPMS diagnostic trouble
code procedures for the DTC. Refer to
