DISASSEMBLY SERVICE POINTS
AA"SNAP RING REMOVAL
Lay the unit with the compressor cover side facing down
and using snap ring pliers, remove the compressor cover
attaching snap ring.
Caution
When removing the snap ring, hold it with fingers to
prevent it from springing away.
AB"TURBINE WHEEL ASSEMBLY REMOVAL
Remove the turbine wheel assembly, striking the
circumference of the compressor cover with a plastic hammer.
The turbine wheel assembly may be a little hard to remove
due to an O-ring put on the outer circumference.
CLEANING
1. Use a clean cleaning oil commercially available. Do not
use corrosive cleaning oils as they could damage to some
parts.
2. Use a plastic scraper or hard brush to clean aluminum
parts.
REASSEMBLY SERVICE POINTS
"AAO-RING INSTALLATION
Apply a light coat of engine oil to a new O-ring and fit in
the turbine wheel assembly groove.
Caution
When installing the O-ring, use care not to damage it. A
damaged O-ring causes oil leaks.
"BATURBINE WHEEL ASSEMBLY
1. Apply a light coat of engine oil to the periphery of the
O-ring.
2. Install the turbine wheel assembly to the compressor cover
in relation to the dowel pin.
Caution
Use care not to damage the blades of turbine wheel
and compressor wheel.

"CASNAP RING INSTALLATION
Lay the assembly with the compressor cover facing down
and fit the snap ring.
Caution
Fit the snap ring with its chamfered side facing up.
"DATURBINE HOUSING INSTALLATION
Install the turbine housing in relation to the dowel pin.
Caution
Use care not to damage the blades of turbine wheel.
"EACOUPLING INSTALLATION
Install the coupling and tighten to the specified torque.
"FAWASTE GATE ACTUATOR OPERATION CHECK
Using a tester, apply a pressure of approx. 100.0 kPa to
the actuator and make sure that the rod moves.
Caution
Do not apply a pressure of more than 113.3 kPa to the
actuator. Otherwise, diaphragm may be damaged. Never
attempt to adjust the waste gate valve.
INSPECTION
TURBINE HOUSING
1. Check the housing for traces of contact with the turbine
wheel, cracks due to overheating, pitching, deformation
and other damage. Replace with a new turbine housing
if cracked.
2. Operate the waste gate valve lever manually to check
that the gate can be operated and closed smoothly.

COMPRESSOR COVER
Check the compressor cover for traces of contact with the
compressor wheel and other damage.
TURBINE WHEEL ASSEMBLY
1. Check the turbine and compressor wheel blades for bend,
burr, damage, corrosion and traces of contact on the
back side and replace if defective.
2. Check the oil passage of the turbine wheel assembly
for deposit and clogging.
3. In the case of water cooled type, check also the water
passage for deposit and clogging.
4. Check the turbine wheel and compressor wheel for light
and smooth turning.

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 (*).

TROUBLESHOOTING
BASIC TROUBLESHOOTING CONDITIONS
Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points.
NOTE
Before starting the troubleshooting procedure, make sure that the following items have been checked
okay.
DIs the appropriate steering wheel installed at the center of the steering column shaft correctly?
DAre the tire, wheel size, specifications, air pressure, balance, and wear state normal?
DIs the wheel alignment normal?
DHas the engine, suspension, etc. been remodeled in such a way that it will affect the ACD and AYC
systems?
DIAGNOSIS FUNCTION
READING DIAGNOSIS CODE
Read a diagnosis code by the MUT-IIor ACD mode indicator
lamp. (Refer to GROUP 00 - How to Use Troubleshooting/
Inspection Service Points.)
NOTE
Connect the MUT-IIto the diagnosis connector (16-pin).
ERASING DIAGNOSIS CODES
When using the MUT-II
Connect the MUT-IIto the diagnosis connector (16-pin) and
erase the diagnosis code.
Caution
Turn the ignition switch to the “LOCK”(OFF) position
before connecting or disconnecting the MUT-II.
