SRS – General Information52B-2
GENERAL INFORMATION
To improve safety, the SRS is available as optional
part.
The SRS consists of two air bag modules, SRS
air bag control unit (SRS-ECU), SRS warning lamp
and clock spring. One air bag is located in the
centre of the steering wheel and another above
the glove box. Each air bag has a folded air bag
and an inflator unit. The control unit under the floor
console monitors the system and has a safing G
sensor and an analog G sensor. The warning lamp
on the instrument panel indicates the operationalstatus of the SRS. The clock spring is installed
in the steering column.
Only authorized service personnel should do work
on or around the SRS components. Those service
personnel should read this manual carefully before
staring any such work. Extreme care must be used
when servicing the SRS to avoid injury to the service
personnel (by inadvertent deployment of the air
bags) or the driver (by rendering the SRS
inoperative).

SRS – SRS Service Precautions52B-3
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag during
servicing, read and carefully follow all the
precautions and procedures described in this
manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-5.
3. Never Attempt to Repair the Following
Components:

SRS air bag control unit (SRS-ECU)

Clock Spring

Air Bag Module
(Driver‘s side or front passenger’s side*)NOTE
*: Vehicles with front passenger’s air bag
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENT SERVICE procedures in this manual,
starting at page 52B-22.
4. After disconnecting the battery cable, wait 60 seconds
or more before proceeding with the following work.
The SRS system is designed to retain enough voltage
to deploy the air bag for a short time even after the
battery has been disconnected, so serious injury may
result from unintended air bag deployment if work
is done on the SRS system immediately after the
battery cables are disconnected.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If any of the connectors are diagnosed as
faulty, replace the wiring harness. If the wires are
diagnosed as faulty, replace or repair the wiring harness
according to the following table.

NOTE
*: Vehicles with front passenger’s air bag
6. SRS components should not be subjected to hear over 93C, so remove the SRS-ECU, air bag
module and clock spring before drying or baking the vehicle after painting.
7. Whenever you finish servicing the SRS, check warning lamp operation to make sure that the system
functions properly. (Refer to P.52B-14.)
8. Make certain that the ignition switch is LOCK (OFF) position when the MUT-II is connected or
disconnected.
9. If you have any questions about the SRS, please contact your local distributor.

SRS – Troubleshooting52B-9
Code No.24, 25, 64 or 65 Front passenger’s side air bag

These diagnosis codes are output if there is abnormal resistance between the input
terminals of the driver’s side air bag module (squib).
The trouble causes for each diagnosis code No. are as follows.
Malfunction of wiring harnesses or connectors

Malfunction of front passenger’s side air bag module

NOTE
*: The connector in the squib circuit has a built-in short bar which short-circuits between plus (+) lead and minus
(–) lead of the squib circuit when the connector is not being connected to prevent an accidental air bag deployment
possibly caused by static electricity, etc. Therefore, malfunction of the connector can also be caused by this
short bar which fails to be released even when the connector is reconnected if it is damaged.

SRS – SRS Maintenance52B-16
SRS COMPONENT VISUAL CHECK
Turn the ignition key to the LOCK (OFF) position, disconnect
the negative battery cable and tape the terminal.
Caution
Wait at least 60 seconds after disconnecting the battery
cable before doing any further work. (Refer to P.52B-3.)
SRS CONTROL UNIT (SRS-ECU)
1. Check SRS-ECU case and brackets for dents, cracks,
deformation or rust.
Caution
The SRS may not activate if the SRS-ECU is not
installed properly, which could result in serious injury
or death to the vehicle’s driver or front passenger.
2. Check connector for damage, and terminals for
deformation or rust.
Replace SRS-ECU if it fails visual check.
(Refer to P.52B-24.)
AIR BAG MODULES, STEERING WHEEL AND CLOCK
SPRING
1. Remove the air bag modules, steering wheel and clock
spring. (Refer to P.52B-25.)
Caution
The removed air bag modules should be stored in
a clean, dry place with the pad cover face up.
2. Check pad cover for dents, cracks or deformation.
