12. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
If any malfunction is deployed, Touch “ERASE” in the “SELF-
DIAG [CURRENT]” screen, and check the display.
13. Turn ignition switch OFF, then turn off and disconnect CONSULT-II.
14. Turn ignition switch ON, and check the system with the SRS air bag warning lamp (User mode).
15. Check that no malfunction is detected. Now the diagnosis is complete.
DIAGNOSTIC PROCEDURE 3
Inspecting SRS Malfunctioning Record
If any malfunction is detected in “SRS Operation Check”, but no malfunction is detected in “SELF-DIAG [CUR-
RENT]” on CONSULT-II, carry out the following steps.
1. CHECK BATTERY VOLTAGE
Disconnect both battery cables and check that the battery voltage is 9 V or more.
OK or NG
OK >> GO TO 2.
NG >> Charge the battery.
2. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULT AFTER REPAIRING.
Is it the first time for maintenance of SRS?
YES or NO
YES >> GO TO 3.
NO >> Erase the self-diagnostic results, and Check the “SRS Operation Check”. Refer to SRS-17, "
SRS
Operation Check" .
3. CHECK “SELF-DIAG [PAST]” BY CONSULT-II
Store the memory in “SELF-DIAG [PAST]”.
YES or NO
YES >> Repair the part of “SELF-DIAG[PAST]”.
NO >> Check the “TROUBLE DIAG RECORD”, and then repair it. Refer to SRS-22, "
Diagnostic Code
Chart" .
