7. If no malfunction is detected on “SELF-DIAG [CURRENT]”,
repair of SRS is completed. Go to step 8.
If any malfunction is displayed on “SELF-DIAG [CURRENT]”,
the malfunctioning part is not repaired completely or another
malfunctioning part is detected. Go to DIAGNOSTIC PROCE-
DURE 2, page RS-50, and repair malfunctioning part com-
pletely.
SRS773
8. Touch “ERASE”.
NOTE:
Touch “ERASE” to clear the memory of the malfunction
(“SELF-DIAG [PAST]”).
If the memory of the malfunction in “SELF-DIAG [PAST]” is not
erased, the User mode shows the system malfunction by the
operation of the warning lamp even if the malfunction is repaired
completely.

9. Touch “BACK” key of CONSULT-II to “SELECT SYSTEM”
screen. Touch “SELF-DIAG [PAST]”.
SRS702
10. Check that no malfunction is detected on “SELF-DIAG
[PAST]”.
11. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM”
appears in order to return to User mode from Diagnosis mode.
12. Turn ignition switch “OFF”, then turn off and disconnect CON-
SULT-II.

warning lamp — Diagnosis mode
NOTE:
SRS will not enter Diagnosis mode if no malfunction is
detected in User mode.
1. Turn ignition switch “ON”.
2. After “AIR BAG” warning lamp lights for 7 seconds, turn igni-
tion switch “OFF” within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 three times.
5. Turn ignition switch “ON”.
SRS is now in Diagnosis mode.
6. “AIR BAG” 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
