DIAGNOSTIC PROCEDURE 7
1. CHECK THE DEPLOYMENT OF AIR BAG MODULE
Is air bag module deployed?
YES or NO
YES >> Refer to SRS-50, "COLLISION DIAGNOSIS" .
NO >> GO TO 2.
2. CHECK THE AIR BAG FUSE
Check 10A fuse [No.13, located in fuse block (J/B)].
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace “AIR BAG” fuse and turn ignition switch ON.
Does the
“AIR BAG” fuse blow again?
YES >> Repair or replace main harness.
NO >>INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is “AIR BAG” displayed on CONSULT-II?
YES or NO
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno-
sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK >> Replace diagnosis sensor unit.
NG >> Connect “AIR BAG” warning lamp and diagnosis sensor unit connector properly. If “AIR BAG”

3. Remove the screws then remove the steering switch.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Fix the air bag module harness (shown as A in the figure) to
the harness fixing hook (shown as B in the figure).
Be careful not to damage the harness while installing.
Tighten the special bolts after exactly adjusting the centers of fixing holes on the air bag module
side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged and the
module is not installed securely.
After the work is completed, make sure no system malfunction is detected by air bag warning
lamp.
In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis func-
tion and delete the memory by CONSOULT–II.
In case that malunction is still detected after the above operation, peform self-diagnosis to repair
malfunctions. Refer to SRS-19, "
SRS Operation Check" .

CAUTION:
The spiral cable may snap by steering operation if the cable
is installed in an improper position.
The neutral position is set as follows.
Turn quietly the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and harf turns) and
stop turning at the point on which the stopper insertion
holes are in the same position.
The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper
is removed.
Do not turn the spiral cable rashly and also beyond the limit
number of turns. (These will cause cable snap.)
Adjust the spiral cable locating pin (showed as A inthe fig-
ure) to the steering wheel locating pin hole (showed as C in
the figuer).
Secure the air bag harness with the harness fixing hook.
After the work is completed, make sure no system malfunc-
tion is detected by air bag warning lamp.
In case that malfunction is detected by the air bag warning
lamp, reset by the self-diagnosis function and delete the
memory by CONSULT
II.
In case that malfunction is still detected after the above
operation, perform self-diagnosis to repair malfunctions.
