TIRE INFLATION PRESSURE CHECKM3lFDA.E
Check the inflation pressure of the tires. If it is not within the
standard value, make the necessary adjustment.
TIRE WEAR CHECKMJlFBAC
Measure the tread depth of tires.
Limit: 1.6 mm
(.06 in.)
If the remaining tread depth is less than the limit, replace the
tire.
NOTE
When the tread depth of tire is reduced to 1.6 mm (.06 in.) orless, wear indicator will appear.
WHEEL RUNOUT CHECKM31 FCAEJack up the vehicle so that the wheels are clear of the floor.
While slowly turning the wheel, measure wheel runout with a
dial indicator.
Limit:
Radial2.0 mm
(.08 in.)
Lateral2.0 mm (.08 in.)
If wheel
runout exceeds the limit, replace the wheel.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(I)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3000GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, aiir bagmodule, clock spring, interconnecting wiring.Other SRS-related components (that may have 1:o be
removed/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
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 the driver (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
Ei2B -Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of theSRS or any SRS-related component.

ON-VEHICLE INSPECTIONIM33FHAD1. WARNING INDICATION BY ECS INDICATOR LIGHT
If a problem associated with the following items occurs, theECS indicator light (Tour Sport) in the combination light
flashes at intervals of 0.5 sec. At the same time, the
self-diagnosis code associated with the problem is outputto the diagnosis connector.
Warning Indication Items
l G sensor
l Steering angular velocity sensor
l Vehicle speed sensor
lDamping force changeover actuator (including position
detection switch)
2. SELF-DIAGNOSIS OUTPUT CHECK
(I) Check the self-diagnosis code.
(2) After the defective portion has been repaired, erase theself-diagnosis code. (If the defective portion is not
completely repaired, it may be impossible to erase the’self-diagnosis code by the MUT.)d
(3) Perform self-diagnosis output check again and checkthat the self-diagnosis code is good.

(1) Set the ignition switch to OFF.
(2) Connect the positive (+) terminal of the voltmeter to
the No. 3 terminal of the diagnosis connector beside the
junction block and connect the negative (--) terminal ofthe voltmeter to the No. 12 terminal.
(3) Set the ignition switch to ON.
(4) Read the self-diagnosis code on the basis of the
deflection of the pointer of the voltmeter.
(5) Based on the self-diagnosis code, repair the associated
defective portion.(6) Set the ignition switch to OFF.
(7) Disconnect the battery cables from the battery termi-
nals and reconnect them more than
10 seconds
thereafter.(8) Set the ignition switch to ON, perform self-diagnosis
check again, and check that the self-diagnosis code is
good.

If the master cylinder is empty of brake fluid, bleed the cylinder
as follows.
(1) Fill the reserve tank with brake fluid.
(2) Depress and hold the brake pedal.
(3) Let your fellow worker plug the master cylinder outlet with
finger.
(4) Keeping the condition (3), release the brake pedal.
(5) Repeat steps
(2) to (4) three to four times while filling the
master cylinder with brake fluid.
BLEEDING THE BRAKE PIPE LINE
Bleed the brake pipe line with the engine running in the order
shown in the illustration.
Caution
When adding brake fluid on vehicles with ABS, be sure to
fit the filter to the reserve tank.
FRONT DISC BRAKE PAD CHECK AND REPLACE-
MENTM35FQAG
NOTEThe brake pads have wear indicators that contact the brake disc
when the brake pad thickness becomes 2 mm
(.079 in.), and
emit a squealing sound to warn the driver.

1. Visually check the brake pad thickness through the inspec-
tion hole in the caliper body.
Standard value: IO.0 mm
(.39 in.)
Limit: 2.0 mm (.08 in.)
Caution
Replace the pad if worn beyond the limit. At this time,
replace the pads on right and left wheels as a set.
2. Remove the guide pin, raise the caliper assembly, and
support it with a wire, etc.
Caution
The guide pin has been coated with special
Igrease. Do
not wipe off the special grease on the lock pin, and do
not contaminate the lock pin.
3. Remove the following parts from the caliper support.@ Pad and wear indicator assembly
8 F$$ assembly
3 I@ Outer shim
4. Measure the rotating torque of the hub with the pads
removed to determine brake drag torque after pads are
installed.
5. Install the pad clips to the caliper support in position.

6. Apply repair kit grease to both sides of the inner shims.
Specified grease: Brake grease SAE 5310,NLGI No. 1
Caution
1. Make sure that the friction surfaces of pads and
brake discs are free of grease- and other
contami-nants.
2. The grease should never squeeze out from around
the shim.

drag torque after pad installation.
On vehicles with VCU-equipped LSD, disengage the drive
shaft and companion flange.
NOTESecure the disc to the hub with wheel nuts.
6. Securely attach the pad clip to the caliper support.
Caution
Do not deposit
&ease or other dirt on pad or brake disc
friction surfaces.
7.Clean the piston and then push the piston into the cylinder.
8.With care not to allow the piston boot to be wedged, lower
the caliper assembly and fit the lock pin.
9. Check brake drag torque as follows.
(I) Start engine and hold brake pedal down for 5 seconds.
[Approx. 200 N (44
Ibs.)](2) Stop engine.
(3) Turn brake disc forward
10 times.
(4) Check brake drag torque with spring scale.
If the difference between brake drag torque and hub torque
exceeds the standard value, disassemble piston and clean
piston. Check for corrosion or worn piston seal, andcheck
the sliding condition of the lock pin sleeve and guide
pinl/jsleeve.
Standard value: 70 N (15.4
