will not be lowered even if something becomes jammed in it.

If the limit switch is always off

If there is an open circuit in the harness between the limit switch and the power
window main switch or the power window sub-switch

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 (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: impact sensors, SRS diagnosis unit, 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 (*).

NOTE
The sensor cable marked with * is available as service part.
7. SRS components should not be subjected to heat over 93
C, so remove the SRS diagnosis unit,
air bag module, clock spring and front impact sensors before drying or baking the vehicle after painting.
8. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to P.52B-16.)
9. Make certain that the ignition switch is OFF when the MUT-II is connected or disconnected.
10. If you have any questions about the SRS, please contact your local distributor.
NOTE
SERIOUS INJURY CAN RESULT FROM UNINTENDED AIR BAG DEPLOYMENT, SO USE ONLY
THE PROCEDURES AND EQUIPMENT SPECIFIED IN THIS MANUAL.

SRS ± Troubleshooting52B-8
Code No. 21 or 22 Air bag module (squib) systemProbable cause
(1) These diagnosis codes are output if there is abnormal resistance between the
input terminals of the air bag module (squib).
The trouble causes for each code No. are as follows. (Refer to chart 1.)
(2) Diagnosis codes 21 and 22 are sometimes generated in combination with
malfunction codes relating to the front impact sensor (code Nos. 11, 12 and 13),
but sometimes only one may be output instead of both being memorized. Because
of this, the front impact sensor should also be inspected at the same time. The
relationships between the codes are as follows. (Refer to chart 2.)

Caution
Do not attempt to measure the air bag module (squib) circuit resistance. Use of a tester in measuring
the circuit resistance will supply current to the squib, or erroneous deployment due to static electricity
could cause serious injury.
