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.

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-46, 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.
NOTE:
When a malfunction is detected, switch from Diagnosis mode
to user mode by turning the ignition switch as follows:
