TPMS warning light bulb check signal <TPMS 

warning light: illuminated>

• The TPMS receiver turns on the TPMS warning 

light for 3 seconds when the ignition switch is 
turned to the "ON" position. The driver can judge 
disconnection of the TPMS warning light if it does 
not come on.

• After the 3 seconds illumination, the TPMS 

receiver turns off the TPMS warning light for 0.2 
second, so that the mechanic can detect the fail-
ure of the illumination circuit through the TPMS 
warning light ON in the tire pressure warning 
state.

Tire pressure warning signal <TPMS warning 

light: illuminated>

• When a received tire pressure sensor ID matches 

the registered tire pressure sensor ID in the 
TPMS receiver, and the received tire pressure 
value is lower than the threshold value, then the 
TPMS receiver considers it in the tire pressure 
warning state and outputs the warning and sets 
the diagnostic trouble code.

• Also while the vehicle is parked (ignition switch: 

"LOCK" (OFF) position), the TPMS receiver mon-
itors tire pressure. And it outputs the warning 
when the ignition switch is turned to the "ON" 
position, if the tire pressure is in the warning 
state.

• When the received tire pressure sensor ID 

matches with the registered tire pressure sensor 
ID in the TPMS receiver, and the tire pressure 
value received is higher than the threshold value, 
the TPMS receiver clears the tire pressure warn-
ing against the tire pressure sensor ID. If the tire 
warning is cleared for all the tires including the 
spare tire, the TPMS warning light will go out.

TIRE PRESSURE THRESHOLD VALUES

TPMS warning signal (EEPROM abnormality) 

<TPMS warning light: flashes>

• The TPMS receiver checks EEPROM. When 

information in the EEPROM is considered abnor-
mal due to tire pressure sensor ID deterioration, 
etc., the TPMS receiver outputs the warning and 
sets a diagnostic trouble code.

TPMS warning signal (reception failure) <TPMS 

warning light: flashes>

• The TPMS receiver outputs the warning signal 

and sets a diagnostic trouble code when the sig-
nals matched with the registered tire pressure 
sensor IDs in the TPMS receiver were not 
received.

• When the TPMS receiver receives normal signals 

for the tire pressure sensor ID that had reception 
failure problems, the TPMS receiver clears the 
warning.

TPMS warning signal (TPMS transmitter battery 

voltage abnormality) <TPMS warning light: 
flashes>

• The TPMS receiver is considered to be in system 

warning state due to TPMS transmitter low bat-
tery voltage against its tire pressure sensor ID. 
The receiver outputs the warning signal and sets 
a diagnostic trouble code under the following 
conditions. The received tire pressure sensor ID 
matches the registered tire pressure sensor ID in 
the TPMS receiver, and function code ’Low Bat-
tery’ is received consecutively.

• The TPMS receiver clears the warning state 

against its tire pressure sensor ID under the fol-
lowing conditions. The received tire pressure 
sensor ID matches with the registered tire pres-
sure sensor ID in the TPMS receiver, and ’Normal 
Pressure’ function code is received consecu-
tively.

TPMS warning signal (vehicle speed signal 

abnormality) <TPMS warning light: flashes>

• When vehicle speed input is always less than 5 

km/h (3 mph), the TPMS receiver judges the sys-
tem to be vehicle speed signal abnormality warn-
ing and outputs the warning and set a diagnostic 
trouble code.

• The warning will be cleared when vehicle speed 

signal is over 5 km/h (3 mph) for over 1 second 
with the ignition switch in the "ON" position.

TPMS warning signal (Transmitter OFF mode) 

<TPMS warning light: flashes>

• Transmitting signal of the TPMS transmitter 

should be stopped during transportation to dealer 
because it will break Japanese radio wave regu-
lation.

• OFF mode is canceled at dealer. So, output 

warning and set DTC 17 (Transmitter OFF Mode, 
ALL Tire) during transmitter OFF mode for 
reminding cancel of OFF mode.

• When the TPMS receiver receives the signals 

from all registered tire pressure sensor, the 
TPMS receiver clears the warning.

TPMS OPERATIONAL 
CHARACTERISTICS

• The TPMS receiver monitors the tire pressure of 

road tires except spare tire.

• The TPMS transmitter includes a roll switch that 

senses tire rotation. The TPMS receiver can 
determine which tires are rotating (road tire) and 
stationary (spare tire).

• The recommended cold tire pressure at normal 

condition for Montero is 200 kPa (29 psi). The 
TPMS warning light will turn ON and DTC 
23/27/32/36/41/ will be stored in memory when 
the air pressure in any road tire is below 158 kPa 
(23.0 psi).

• The TPMS warning light will turn OFF and the 

DTC 23/27/32/36/41 in memory will be eliminated 
when the tire pressure is increased to at least 
174 kPa (25.25 psi).

• Customers may experience what appears to be 

an "intermittent" tire pressure warning light 
because the air pressure in the tires normally 
fluctuates under various operating conditions:

• In cold weather, tire pressure will become 

lower due to the ambient temperature, and 
the TPMS warning light will turn ON if tire 
pressure drops below 158 kPa (23.0 psi). The 
tire pressure will increase after driving (tires 
warm up), and the TPMS warning light will 
turn OFF.

Regardless of the ambient temperature, set 
the tire pressure to 200 kPa (29 psi) with the 
tires cold [vehicle has been parked for at least 
three hours or driven less than 1.6 kilometers 
(one mile) after having been parked for three 
hours].
NOTE: Tire pressure changes at slightly less 
than 6.9 kPa (1 psi) per 5.5

°

C (10

°

F) of ambi-

ent temperature change.
For example, climates with seasonal temper-
atures that vary from 32

°C (90°F) in the sum-

mer to -12

°C (10°F) in the winter have a 44 

degree Celsius (80 degrees Fahrenheit) tem-
perature change. This can result in an 
approximate 55 kPa (8 psi) change in tire 
pressure. In this example:

• If the tire pressure was set when the ambi-

ent temperature was 32

°C (90°F) in the 

summer, it can be about 145 kPa (21 psi) 
on the coldest day in the winter. This will 
cause the TPMS warning light to turn on.

• If the tire pressure was set when the ambi-

ent temperature was -12

°C (10°F) in the 

winter, it can be about 255 kPa (37 psi) on 
the hottest day of the summer. This will 
create a rougher ride.

The important point is that customers should have 
their tire pressure seasonally adjusted.

PRECAUTIONS

M1311004300022

• Transmitting signal of the TPMS transmitter 

should be stopped during transportation to dealer 
because it will break Japanese radio wave regu-
lation.

• OFF mode is canceled at dealer. So, output 

warning and set DTC 17 during transmitter OFF 
mode for reminding cancel of OFF mode.

• Do not use an aerosol puncture-repair spray. 

Such a spray could damage the tire pressure 
sensor (TPMS transmitter). 

• Whenever the TPMS transmitters and/or TPMS 

receiver are replaced with new ones, the tire 
pressure sensor IDs must be registered into the 
TPMS.

• Install the spare tire as shown. If the spare tire 

valve (TPMS transmitter) is not positioned as 
shown, the roll switch, which is incorporated in 
the TPMS transmitter, may operate. In that case, 
the system may determine the spare tire as a 
road tire incorrectly. 

• The use of non-genuine wheels may cause the 

improper installation of the TPMS transmitters, 

possibly resulting in air leakage and damage to 
the TPMS transmitter.

• When the tire is removed from the wheel, a spe-

cial procedure must be observed to avoid the 
TPMS transmitter damage. Refer to "TPMS 
transmitter Removal and Installation (

P.31-97

)".

• The grommet at base of valve stem should be 

replaced with a new one every five years or when 
the tire is replaced. For the replacement proce-
dure, refer to "TPMS transmitter Removal and 
Installation (

P.31-97

)".

• After the TPMS transmitter is replaced and the 

tires are inflated, retighten the valve nut (TPMS 
transmitter mounting nut) to the specified torque, 
refer to "TPMS transmitter Removal and Installa-
tion (

P.31-97

)".

• Replace the TPMS transmitter when the TPMS 

transmitter battery is discharged. The battery 
cannot be removed from the TPMS transmitter. 
Nominal service life of the battery is 10 years or 
160,000 km (100,000 miles).

• If the valve core and valve cap are replaced, use 

a genuine replacement part. The valve core is 
similar to a conventional one, but nickel plating 
was applied to avoid electric corrosion.

• TPMS may not work normally in the following cir-

cumstances:

• A wireless facility or device using the same 

frequency with the TPMS transmitter is near 
the vehicle.

• Snow or ice is stuck inside the wheel houses 

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 transmit-

ters are being used.

• Wheels whose tire pressure sensor IDs are 

not registered by the vehicle are being used.

NOTE: Tire inflation pressures vary with the ambient 
temperature. If the vehicle is subjected to large varia-
tions in ambient temperature, the tire inflation pres-
sures may be under-inflated (causing the TPMS 
warning light to come on) when the ambient temper-
ature is relatively low. If the TPMS warning light 
comes on, adjust the tire inflation pressure.
NOTE: If any of the road wheel tires do not contain a 
TPMS transmitter, and the customer continues driv-
ing, the TPMS warning light will flash.
