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 (*).

NOTES WITH REGARD TO DIAGNOSIS
1. The phenomena listed in the following table are not abnormal.
PhenomenonExplanation of phenomenon
System check soundWhen starting the engine, a thudding sound can sometimes be heard coming from inside
the engine compartment, but this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound1. Sound of the motor inside the ABS hydraulic unit operation. (whine)
2. Sound is the generated along with vibration of the brake pedal. (scraping)
3. When ABS operates, sound is generated from the vehicle chassis due to repeated
brake application and release.
(Thump: suspension; squeak: tyres)
System check soundWhen depressing the brake pedal during driving, a shock is sometime felt.
2. For road surfaces such as snow-covered roads and gravel roads, the braking distance for vehicles
with ABS can sometimes be longer than that for other vehicles. Accordingly, advise the customer
to drive safely on such roads by lowering the vehicle speed and not being too overconfident.
3. Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the “Comment” are satisfied when checking the trouble
symptom again.

ABS WARNING LAMP INSPECTION
Check that the ABS warning lamp illuminates as follows.
1. When the ignition key is turned to “ON”, the ABS warning
lamp illuminates for approximately 3 seconds and then
switches off.
2. When the ignition key is turned to “START”, the ABS
warning lamp remains illuminated.
3. When the ignition key is turned from “START” back to
“ON”, the ABS warning lamp illuminates for approximately
3 seconds and then switches off.
NOTE
The ABS warning lamp may remain on until the vehicle
reaches a speed of several km/h. This is limited to cases
where diagnosis code Nos.21 to 24, 41 to 44, 53 or 55
have been recorded because of a previous problem
occurring. In this case, the ABS-ECU keeps the warning
lamp illuminated until the problem corresponding to that
diagnosis code can be detected.
4. If the illumination is other than the above, check the
diagnosis codes.
DIAGNOSIS FUNCTION
READING DIAGNOSIS CODES
Read a diagnosis code by the MUT-IIor ABS warning 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 key to the “LOCK” (OFF) position before
connecting or disconnecting the MUT-II.

When not using the MUT-II
NOTE
If the ABS-ECU function has been stopped because of fail-safe
operation, it will not be possible to erase the diagnosis codes.
1. Stop the engine.
2. Use the special tool to earth terminal (1) (diagnosis control
terminal) of the diagnosis connector.
3. Turn on the stop lamp switch. (Depress the brake pedal.)
4. After carrying out steps 1. to 3., turn the ignition switch
to “ON”. Within 3 seconds after turning the ignition switch
to “ON”, turn off the stop lamp switch (release the brake
pedal). Then, turn the stop lamp switch on and off a
total of 10 times.

Caution
1. If steering movements are made when driving at high speed, or when driving on road surfaces
with low frictional resistance, or when passing over bumps, the ABS may operate even though
sudden braking is not being applied. Because of this, when getting information from the customer,
check if the problem occurred while driving under such conditions as these.
2. During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such
phenomena are due to intermittent changes in hydraulic pressure inside the brake line to prevent
the wheels from locking and is not an abnormality.

Inspection Procedure 3
When the ignition key is turned to “ON” (engine stopped),
the ABS warning lamp does not illuminate.
Probable cause
The cause may be an open circuit in the lamp power supply circuit, a blown lamp,
or an open circuit between the ABS warning lamp and the earth.DBlown fuse

Check whether the ABS warning lamp bulb is burnt out.
Does the ABS warning lamp illuminate when the ABS-ECU
connector B-123 is disconnected and the ignition switch is turned
to ON?YES
Repair
Replace the combination meter. (Refer to GROUP 54A.)NG

Inspection Procedure 4
Even after the engine is started, the ABS warning lamp
remains illuminated.
Probable cause
The cause is probably a short-circuit in the ABS warning lamp illumination circuit.DMalfunction of combination meter
DMalfunction of wiring harness (short circuit)
DMalfunction of hydraulic unit and ABS-ECU
NOTE
This trouble symptom is limited to cases where communication with the MUT-IIis possible (ABS-ECU
power supply is normal) and the diagnosis code is a normal diagnosis code.
