WARNING REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring, and interconnecting
wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are
indicated in the table of contents by an asterisk (*).

4. Fill with specified oil till the level comes to the lower portion
of oil filler plug hole.
Specified transfer oil:

5. Tighten the oil filler plug to the specified torque.
Tightening torque: 32±2 N·m
FLUID CHECK VEHICLES WITH ACD AND AYC>
1. Remove the maintenance lid located in the luggage
compartment.
2.
If the vehicle has been run, leave it for 90 min. or more
in an ordinary temperature (10_C–30_C) to allow the
accumulator internal pressure to drop.
NOTE
If the ambient temperature is 10_C or less, allow more
time to leave the vehicle to stand idle.

Set the MUT-IIto the 16-pin diagnosis connector. Turn ON
the ignition switch, perform MUT-IIactuator test (Item
No.03), forcibly drive the hydraulic unit and remove the
pressure in the accumulator.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
NOTE
(1) In the actuator test (Item No. 03: Oil Level Check
Mode), the directional valve of the hydraulic unit is
moved to the left and right for 20 times, and then
the differential is cleared automatically. Drive can also
be cleared forcibly using the Clear key of the MUT-II.
(2) If the function has been stopped by fail-safe, the
hydraulic unit cannot be cleared forcibly.
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: Dia Queen ATF SP III
5. Reinstall the maintenance lid.

BLEEDING VEHICLES WITH ACD AND AYC>
1. Lift up the vehicle.
2. Set the MUT-IIto the 16-pin diagnosis connector.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
3. Turn the ignition switch to the “ON” position.
4. Set the steering wheel in the straight-ahead position.
5. Perform the MUT-IIactuator test (Item No.02), and forcibly
drive the hydraulic unit.
NOTE
(1) The actuator test (Item No.01: Bleeding Mode) will
be performed for 5 minutes, after which it will be
cleared automatically. Drive can also be cleared during
forced driving using the clear key of the MUT-II.
(2) If the hydraulic unit function has been stopped by
fail-safe, the hydraulic unit cannot be forcibly driven.
6. Remove the cap of the bleeder screw on the transfer,
and connect the vinyl hose.
7
.Slowly turn the steering wheel to the left or right from
the neutral state. Loosen the bleeder screw, and check
that air is discharged together with the fluid.
8
.After the air is discharged, tighten the bleeder screw,
and return the steering wheel to the neutral state.
Caution
During bleeding, replenish the fluid so that some
always remains in the oil reservoir.
9. Repeat steps 6 and 7 several 2 to 3 times, and after
checking that no more air mixes in, tighten the bleeder
screw at the specified torque.
Tightening torque: 5±1 N·m
10. After bleeding, check the fluid level. (Refer to P. 22A-41.)
Caution
If bleeding is not performed completely, noise may
be produced from the hydraulic unit, or the durability
of the pump, etc. may drop.
11. On vehicles with AYC, perform bleeding when the
hydraulic unit is removed. (Refer to GROUP 27B -
On-vehicle Service.)
