WARNINGS 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 the 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: front impact sensors, 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 (*).

ON-VEHICLE SERVICE
OPERATION TEST OF MITSUBISHI SC
1. Connect the MUT-
IIto the 16-pin diagnosis connector.
Caution
Turn the ignition switch to the LOCK (OFF) position
when connecting and disconnecting the MUT-
II.
2. Move the shift lever to the neutral
lever to the P range.
3. Start the engine.
4. Use the MUT-
IIto activate the Actuator Test (item No.05)
while depressing the accelerator pedal fully. Check that
the engine speed should decrease gradually.
Caution
Activate the Actuator Test for three seconds.
Release the accelerator pedal immediately after the
Actuator Test is complete, or the engine speed will
rise.
NOTE
During the Actuator Test, the SC-ECU transmits the signal,
which requests no torque and wide open throttle, to the
engine-ECU or engine-A/T-ECU for three seconds.
WHEEL SPEED SENSOR (FR) CHECK
Refer to Basic Manual GROUP 35B - On-vehicle service.
VEHICLE SPEED SENSOR CHECK
Refer to Basic Manual GROUP 54A - Combination Meter.
