DIAGNOSTIC PROCEDURE 3
Final inspection after repairing SRS by using CONSULT-II — Diagnosis mode
Refer to GI-38, "
CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]”,
repair of SRS is completed. Go to step 2.
If any malfunction is detected on “SELF-DIAG [CURRENT]”, the
malfunctioning part is not repaired completely or another mal-
functioning part is detected. Go to SRS-22, "
DIAGNOSTIC
PROCEDURE 2" , and repair malfunctioning part completely.
2. Touch “ERASE”.
NOTE:
Touch “ERASE” to clear the memory of the malfunction (“SELF-
DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is repaired
completely.
3. Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE”
screen. Touch “SELF-DIAG [PAST]”.

DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM DIAGNOSTIC PROCEDURE 2)
Inspecting SRS malfunctioning record
1. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULT AFTER REPAIRING
Is it the first time for maintenance of SRS?
YES or NO
YES >> Go to SRS-22, "DIAGNOSTIC PROCEDURE 2" .
NO >> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased
after repair. Go to SRS-27, "
DIAGNOSTIC PROCEDURE 3" .
DIAGNOSTIC PROCEDURE 5
Inspecting SRS intermittent malfunction by using CONSULT-II — Diagnosis mode
Refer to GI-38, "
CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [PAST]”.
2. If diagnostic codes are displayed on “SELF-DIAG [PAST]”, go to
step 5.
a. If no malfunction is detected on “SELF-DIAG [PAST]”, touch
“BACK” and go back to “SELECT DIAG MODE”.

DIAG [PAST]” or “TROUBLE DIAG RECORD”)" .
7. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears.
8. Turn ignition switch OFF, then turn off and disconnect CON-
SULT-II, and both battery cables.
9. Repair the system as outlined by the “Repair order” in “Intermit-
tent Malfunction Diagnostic Code Chart”, that corresponds to the
self-diagnosis result. For replacement procedure of component
parts, refer to the Removal and Installation procedure for the appropriate component.
10. Go to SRS-27, "

Removal and InstallationNHS0009C
REMOVAL
CAUTION:

Before servicing, turn ignition switch OFF, disconnect both battery terminal and wait at
least 3 minutes.

Do not use air tools or electric tools for servicing.

Always work from the side of air bag module. Do not work from the front of it.

Always place air bag module with pad side facing upward.

Do not make an impact to the air bag module by dropping etc. Replace the air bag module if it has
been dropped or sustained an impact.
1. Remove the side lids (left/right).
2. Remove the driver air bag module.

Using Tamper resistant TORX bit, remove the TORX bolt at left and right.

Disconnect the harness connector with the driver air bag module rassed a bit.
NOTE:

For installing/removing driver air bag module connector,
insert thin screwdriver wrapped in tape into notch, lift lock
and remove connector.

Install connector with lock raised, and push lock into con-
nector.

After installing the connector, make sure that the lock is

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.
