ON-VEHICLE SERVICE
SPEEDOMETER CHECK
(1) Ensure that tire pressure indicates the value of tirepressure label.
(2) Place the vehicle on speedometer teste r.
(3)
(4) For prevention of front wheel lateral runout, install
extension fittings on front towing eye and tie down hook,
and install both ends on anchor plate.
(5) For prevention of vehicle from starting out, install chain or wire (the other end of which is tightly fixed on rear
towing eye) on the vehicle.
(6) Ensure that speedometer indication range is within standard value, or pointer deflection is within limit value.
Caution
During operation, avoid excessive acceleration and
deceleration.
Standard value:
Vehicle speed km/h4080120160

TACHOMETER CHECK
1. Insert paper clip (Zem clip) from harness side of the probe
for detection of engine speed to connect engine speed
indicator.
2. Compare measured values of individual engine speed
with tachometer values, and ensure that indication
allowance is within standard value.
Standard value:
Engine speed (rpm)Indication allowance of tachometer
rpm

FUEL GAUGE UNIT CHECK
Remove fuel gauge unit from fuel tank.
BASIC RESISTANCE OF FUEL GAUGE UNIT
1. When float of fuel gauge unit is in Position F and E,
ensure that resistance between fuel gauge unit terminal
and earth terminal is within standard value.
Standard Value:
Float PositionMain fuel gauge unitSub fuel gauge unit
Position F2±1Ω2±1Ω
Position E41±1Ω69±1Ω
2. When float is moved slowly between Position F and E,
also ensure that resistance is smoothly changing.

UNIT CHECK
1. Drain coolant. (Refer to GROUP 14 - On-vehicle Service)
2. Remove water temperature gauge unit.
3. Put water temperature gauge unit into the hot water in
specified temperature, and ensure that basic resistance
is within standard value.

4. After inspection, apply specified sealant at threads of
water temperature gauge unit, and tighten to the specified
torque.
Semi-drying sealant: 3M ATD Part No.1215 or
equivalent
5. Refill coolant. (Refer to GROUP 14 - On-vehicle Service.)

NOTES ON HEADLAMP ASSEMBLY:
Plastic outer lens are equipped with headlamp assembly. For handling, care should be taken for
the following items:
DHeadlamps should not be illuminated for more than 3 minutes with scratch preventive protectors,
etc. covered on them.
DMasking such as taping should not be attached on outer lens.
DOuter lens surface should not be rubbed with a sharp-edged tool, etc.
DSpecified wax remover should be used for insistently washing.
DAuthorized Mitsubishi Genuine bulbs should be used.
TROUBLESHOOTING
Headlamps are controlled smart wiring system (SWS). For troubleshooting, refer to GROUP 54B.
NOTE
When ETACS-ECU is defective, headlamps can be illuminated only in a low beam mode as fail-safe
function.

HEADLAMP AIMING
PRE-AIMING INSTRUCTION
1. Inspect for badly rusted or faulty headlamp assemblies.
2. These conditions must be corrected before a satisfactory
adjustment can be made.
