Inspecting SRS malfunctioning parts by using ªAIR BAGº
warning lamp Ð Diagnosis mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is
detected in User mode.
1. Turn ignition switch ªONº.
2. After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch ªONº. SRS is now in Diagnosis mode.
6. ªAIR BAGº warning lamp operates in Diagnosis mode as fol- lows:
NOTE:
If SRS does not enter Diagnosis mode even though malfunc-
tion is detected in User mode, check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then
go to DIAGNOSTIC PROCEDURE 7, page RS-53.
If the battery voltage is OK, replace the diagnosis sensor unit.

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-48, 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 on the next page.

Collision Diagnosis
FOR FRONTAL COLLISION
To repair the SRS, perform the following steps.
When SRS (except the side air bag modules) is activated in a collision:
1) Replace the diagnosis sensor unit.
2) Remove the air bag modules (except the side air bag modules) and front seat belt pre-tensioner assem-blies.
3) Check the SRS components using the table shown below:
I 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-38). Ensure entire SRS operation properly.
When SRS is not activated in a collision:
1) Check the SRS components using the table shown below:
I 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-38). Ensure entire SRS operation properly.
