Inspecting SRS malfunction 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 igni-
tion switch ªOFFº within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.

6. ªAIR BAGº warning lamp operates in Diagnosis mode as fol-
lows:
NOTE:
If SRS does not enter Diagnosis mode even though malfunction
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.

Repair order (ªRecheck SRS at each replacement.º)
1. Visually check the wiring harness connection.
2. Replace the harness if it has visible damage.
3. Replace the satellite sensor (LH).
4. Replace the diagnosis sensor unit.
5. Replace the related harness.
* Follow the procedures in numerical order when repairing malfunctioning parts. Confirm whether malfunction is eliminated
using the air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still observed, proceed to the
next step. When malfunction is eliminated, further repair work is not required.

NOTE:
When diagnosis sensor unit is replaced with a new one,
ªAIR BAGº warning lamp will operate in User mode. Check-
ing ªAIR BAGº warning lamp operation in Diagnosis mode
is not required. Go to step 6.
4. If ªAIR BAGº warning lamp operates as shown in No. 1 in
chart above, turn ignition switch ªOFFº to reset from Diagno-
sis mode to User mode and to erase memory of the malfunc-
tion. 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.
5. 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.
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.
