NOTE:
When diagnosis sensor unit is replaced with new one, ªAIR BAGº
warning lamp will operate in User mode. Checking ªAIR BAGº
warning lamp operation in Diagnosis mode is not required. Go to
step 6.
5. If ªAIR BAGº warning lamp operates as shown in No. 1 in chart
above, turn ignition switch ªOFFº to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If ªAIR BAGº warning lamp operates as shown in No. 2 or No.
3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-60, and repair mal-
functioning part completely.
6. Turn ignition switch ªONº. ªAIR BAGº warning lamp operates in
User mode. Compare ªAIR BAGº warning lamp operation to
the chart below.
NOTE:
When a malfunction is detected, switch from Diagnosis mode to
user mode by turning the ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn igni-
tion switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.

Collision Diagnosis=NJRS0033FOR FRONTAL COLLISIONNJRS0033S07To repair the SRS, perform the following steps.
When SRS (except the side air bag) is activated in a collision:
1) Replace the diagnosis sensor unit.
2) Remove the air bag modules (except the side air bag module) and front seat belt pre-tensioner assem-
blies.
3) Check the SRS components using the table shown below:
+Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
4) Install new air bag modules (except the side air bag module) and front seat belt pre-tensioner assemblies.
5) Conduct self-diagnosis using CONSULT-II or ªAIR BAGº warning lamp. Refer to ªSRS Operation Checkº
for details (RS-49). Ensure entire SRS operation properly.
When SRS is not activated in a collision:
1) Check the SRS components using the table shown below:
+Replace any SRS components showing visible signs of damage (dents, cracks and deformation).
2) Conduct self-diagnosis using CONSULT-II or ªAIR BAGº warning lamp. Refer to ªSRS Operation Checkº
for details (RS-49). Ensure entire SRS operation properly.
