If no malfunction is detected on ªSELF-DIAG [CURRENT]º even
though malfunction is detected in ªSRS Operation Checkº, check
the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then go
to DIAGNOSTIC PROCEDURE 3, page RS-42.
If the battery voltage is OK, go to DIAGNOSTIC PROCEDURE 4,
page RS-44, to diagnose the following cases:
ISelf-diagnostic result ªSELF-DIAG [PAST]º (previously stored
in the memory) might not be erased after repair.
IThe SRS system malfunctions intermittently.
8. Touch ªPRINTº.
9. Compare diagnostic codes to ªCONSULT-II Diagnostic Code
Chartº, page RS-40.
10. Touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears in order to return to User mode from Diagnosis mode.
11. Turn ignition switch ªOFFº, then turn off and disconnect
CONSULT-II, and disconnect both battery cables.
12. Repair the system as outlined by the ªRepair orderº in ªCON-
SULT-II Diagnostic Code Chartº, that corresponds to the self-
diagnostic result. For replacement procedure of component
parts, refer to RS-15.
13. After repairing the system, go to DIAGNOSTIC PROCEDURE
3, page RS-42 for final checking.
