DIAGNOSTIC PROCEDURE 6
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-51.
If the battery voltage is OK, replace the diagnosis sensor unit.
