DIAGNOSTIC PROCEDURE 3
Final inspection after repairing SRS by using CONSULT-II — Diagnosis mode
Refer to GI-38, "
CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [CURRENT]”.
a. If no malfunction is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 2.
If any malfunction is detected on “SELF-DIAG [CURRENT]”, the
malfunctioning part is not repaired completely or another mal-
functioning part is detected. Go to SRS-21, "
DIAGNOSTIC
PROCEDURE 2" , and repair malfunctioning part completely.
2. 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.
3. Touch “BACK” key of CONSULT-II to “SELECT DIAG MODE” screen. Touch “SELF-DIAG [PAST]”.

DIAGNOSTIC PROCEDURE 4 (CONTINUED FROM DIAGNOSTIC PROCEDURE 2)
Inspecting SRS malfunctioning record
1. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULTS AFTER REPAIRING
Is it the first time for maintenance of SRS?
YES or NO
YES >> Go to SRS-21, "DIAGNOSTIC PROCEDURE 2" .
NO >> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased after repair. Go to SRS-25, "
DIAGNOSTIC PROCEDURE 3" .
DIAGNOSTIC PROCEDURE 5
Inspecting SRS intermittent malfunction by using CONSULT-II — Diagnosis mode
Refer to GI-38, "
CONSULT-II Start Procedure" .
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Touch “SELF-DIAG [PAST]”.
2. If diagnostic codes are displayed on “SELF-DIAG [PAST]”, go to step 5.
a. If no malfunction is detected on “SELF-DIAG [PAST]”, touch “BACK” and go back to “SELECT DIAG MODE”.

3. Touch “TROUBLE DIAG RECORD”. NOTE:
With “TROUBLE DIAG RECORD”, diagnosis results previously
erased by a reset operation can be displayed.
4. Diagnostic code is displayed on “TROUBLE DIAG RECORD”.
5. Touch “PRINT”.
6. Compare diagnostic codes to SRS-27, "
DIAGNOSTIC PROCE-
DURE 5" .
7. Touch “BACK” key of CONSULT-II until “SELECT SYSTEM” appears.
8. Turn ignition switch OFF, then turn off and disconnect CON- SULT-II, and both battery cables.
9. Repair the system as outlined by the “Repair order” in “Intermit- tent Malfunction Diagnostic Code Chart”, that corresponds to the
self-diagnostic result. For replacement procedure of component
parts, refer to the Removal and Installation procedure for the appropriate component.
10. Go to SRS-25, "
DIAGNOSTIC PROCEDURE 3" , for final inspection.
