TROUBLESHOOTING
1. BASIC TROUBLESHOOTING CONDITIONS
Before starting the troubleshooting procedure, make sure that the following items have been checked
okay.
The correct steering wheel has been properly installed in the neutral position of the steering column
shaft.
Tire and wheel sizes are correct with correct specifications. Inflation pressure, balance, and wear
conditions are okay.
Wheel alignment is correct.
The engine, suspension, and other parts have not been remodeled so as to affect the AYC system.
2. DIAGNOSIS FUNCTION
READING THE DIAGNOSIS CODE
Read the diagnosis code using AYC warning lamp.

3-2 TORQUE TRANSFER MECHANISM
(1) Remove the drain plug to discharge the gear oil.
(2) Fit the drain plug and tighten it to the specified torque.
(3) Remove the filler plug and add the specified gear oil
up to the bottom end of the filler plug hole.
Specified gear oil:
MITSUBISHI GENUINE DIA QUEEN SUPER AYC
FLUID
Quantity used: 0.70
0
0.05dm3{0.700
0.05}
(4) Fit the filler plug and tighten it to the specified torque.
4. FLUID LEVEL CHECK
(1) Remove the maintenance lid located in the luggage
compartment.
(2) If the vehicle has been run, leave it for 5 min. or more
in an ordinary temperature (10C to 30C) to allow the
accumulator internal pressure to drop.
NOTE
If the ambient temperature is less than 10C or less,
allow more time to leave the vehicle to stand idle.
(3) Check that the fluid level in the oil reservoir is in the
range between MAX and MIN.
(4) If the fluid level is lower than MIN, add the specified
fluid.
Specified fluid: MITSUBISHI DIA QUEEN ATF-SPII
(5) Reinstall the maintenance lid.
5. BLEEDING
(1) Lift up the vehicle.
(2) Remove the cap of the left bleeder screw on the torque
transfer differential and connect a vinyl hose.
(3) Gradually turn the steering wheel clockwise from the
straight-ahead position. At this time, loosen the left bleeder
screw and check that fluid is discharged with air.
(4) After air has been completely discharged, tighten the
bleeder screw.
Caution
While the system is being bled of air, add fluid as
necessary to ensure that it is left in the oil reservoir
during the entire procedure.
(5) Repeat steps (3) and (4) two to three times until no air
bubbles are recognized in the fluid that comes out. Then,
tighten the bleeder screw to the specified torque.
Tightening torque: 9 Nm {0.9 kgfm}
(6) Perform steps (2) through (5) for the right bleeder screw.
Note, however, that the steering wheel should be turned
counterclockwise.

HEADLAMP AIMING
Bring the vehicle in the following conditions before aiming
the headlamp.
Check the tires for inflation pressure. Pump them up if
necessary to the labeled pressure level.
Set the vehicle unladen on a level floor.
Place one person (approximately 55 kg) on the driver’s
seat.
1. Position the tester so that its converging lens faces the
high-beam lamp ( marked) center to center at a distance
of 3 m from each other.
2. Aim the headlamps to appropriate standard values using
the aiming adjustment screw.

Check the tires for inflation pressure. Pump them up if
necessary to the labeled pressure level.
Set the vehicle unladen on a level floor.
Place one person (approximately 55 kg) on the driver’s
seat.
Maintain an engine speed of 2,000 r/min to keep the
battery in the charged condition.
1. Position the tester so that its converging lens faces the
fog lamp center to center at a distance of 10 m.
NOTE
Measure the center of the fog lamp as shown.
A: 572.5 mm (from the center of the vehicle body)
B: 360 mm
2. Remove the fog lamp bezel, and using the aiming
adjustment screw, aim the fog lamp to the standard value.
NOTE
The horizontal direction is non-adjustable. If the beam
axis deviation exceeds the standard value, check the
fog lamp to determine if it is installed out of position and
correct if necessary.
