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

FRONT AXLE -General Information26-2
GENERAL INFORMATION
The front axle consists of front hubs, knuckles,
wheel bearings and drive shafts, and it has the
following features.
DThe wheel beearing is unit bearing integrated
with hub (Double-row angular contact ball
bearing).
DThe drive shaft incorporates B.J.-T.J. type
constant velocity joints with high transmission
efficiency and low vibration and noise.DABS rotors for detecting the wheel speeds are
press-fitted to the B.J. outer wheels in vehicles
with ABS or ACD.
NOTE
1. B.J.: Birfield Joint
2. T.J.: Tripod Joint
