WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•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 inad vertent firing of the air bag) or to the driver and
paassenger (from renderin g the SRS inoperative).
•Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
•MITSUBISHI dealer personnel must thoroughly review th is manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before begi nning any service or maintenance of any component of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, 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 (*).

NOTE: When adjusting the jaws in parallel, make
sure the knob is in the position shown in the fig

4. Move the ball joint stud several times and install
the nut on the stud. Using special tool preload
socket (MB990326), measure the ball joint turning
torque.
Standard value: 0.5 − 2.5 N⋅m
5. If the turning torque exceeds the standard value, replace the tie rod end.
6. If the turning torque is under the standard value, check the ball joint for axial play or ratcheting. If
no axial play or ratcheting, the ball joint can be
re-used.
CAUTION
Always use a new ball joint nut as it is a self-lock-
ing nut.
7. Install the tie rod end to the knuckle, then tighten a new self-locking nut to the specified torque.
Tightening torque: 25 ± 5 N⋅m
STATIONARY STEERING EFFORT CHECKM1372001700332
1. With the vehicle stopped on a flat and paved
surface, turn the steering wheel to the straight
ahead position.
2. Start the engine and set the engine idle speed.
Standard value: 750 ± 100 r/min
ACX01122 AB
3. Attach a spring balance to the outer
circumference of the steering wheel and measure
the steering force required to turn the steering
wheel from the straight ahead position to the left
and right (within a range of 1.5 turns). Also check
to be sure that there is no significant change in
the required steering effort.
Standard value:
Steering effort: 29 N or less
Fluctuation allowance: 5.9 N or less
4. If the measured value exceeds the standard value, check and adjust the related parts.

6. Check whether or not the hydraulic pressure is the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa
7. If it is not within the standard value, the probable cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.
8. Turn the steering wheel all the way to the left or right; then check whether or not the retention
hydraulic pressure is the standard value.
Standard value: 8.8 − 9.5 MPa
9. If not the standard value, overhaul the steering gear. Remeasure fluid pressure.
10. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
11. Bleed the system (Refer to P.37-14).

WARNING
•If the vehicle continues to be driven after
the collision absorbing mechanism has
operated, the steering column shaft may
be damaged while it is in use.
•If there is a slack in the one-way capsule,
do not attempt to repa ir it but replace the
steering column shaft assembly.
Inspection Procedure
1. Remove the lower and upper column covers.
CAUTION
Do not release the tilt lever until the steering col-
umn has been installed to complete this inspec-
tion procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock posi-
tion.
