DIAGNOSTIC PROCEDURE 6
Inspect SRS Malfunction Using "AIR BAG" 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 ignition switch OFF within 1 second.
3. Wait more than 3 seconds.
4. Repeat steps 1 to 3 two more times (3 times total).
5. Turn ignition switch ON.
SRS is now in Diagnosis mode. Refer to SRC-13, "
Trouble Diagnosis without CONSULT-III".
CONSULT-III Function (AIR BAG)INFOID:0000000001396363
CONSULT-III can display each diagnostic item using the diagnostic test modes shown following.
Self-Diagnosis Function (Without CONSULT-III)INFOID:0000000001396364
 The reading of these results is accomplished using one of two modes —“User mode” and “Diagnosis mode”.
 After a malfunction is repaired, turn the ignition switch OFF for at least one second, then back ON. Diagnosis
mode returns to the User mode. At that time, the self-diagnostic result is cleared.
AIR BAG diagnostic mode Description
SELF-DIAG [CURRENT]A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-III screen in real time. This refers to a malfunctioning part requir-
ing repairs.
SELF-DIAG [PAST]Diagnosis results previously stored in the memory are displayed on the CONSULT-III screen. The
stored results will remain until memory erasing is executed.
TROUBLE DIAG RECORDWith TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-III screen.
ECU DISCRIMINATED NO.The air bag diagnosis sensor unit for each vehicle model is assigned with its own, individual classifica-
tion number. This number will be displayed on the CONSULT-III screen, as shown. When replacing the
air bag diagnosis sensor unit, refer to the part number for the compatibility. After installation, replace-
ment with a correct unit can be checked by confirming this classification number on the CONSULT-III
screen.
The air bag diagnosis sensor unit discriminated numbers assigned are:
A60C (LHD vehicles with front side air bags only)
A60A (RHD vehicles with front side air bags only)
A60E (LHD vehicles with front side and side curtain air bags)
A60B (RHD vehicles with front side and side curtain air bags)
A611 (vehicles without front side and side curtain air bags)
PASSENGER AIR BAGThe STATUS (readiness) of the front passenger air bag module is displayed. The STATUS displayed
(ON/OFF) depends on the signals supplied to the air bag diagnosis sensor unit from the passenger air
bag deactivation switch. Refer to SRC-8, "
Passenger Air Bag Deactivation Switch" for more informa-
tion.

HOW TO CHANGE SELF-DIAGNOSIS MODE
DIAGNOSTIC PROCEDURE 3
Final Check of SRS Using CONSULT-III—Diagnosis Mode
1. Connect CONSULT-III.
2. If no DTC is detected on “SELF-DIAG [CURRENT]”, repair of SRS is completed. Go to step 3.
If any DTC is detected on “SELF-DIAG [CURRENT]”, the malfunctioning part has not been repaired com-
pletely or another malfunctioning part is being detected. Perform DIAGNOSTIC PROCEDURE 2. Refer to
SRC-11, "
SRS Operation Check".
3. 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.
4. Touch “BACK” key of CONSULT-III. Touch “SELF-DIAG [PAST]”.
5. Check that no malfunction is detected on “SELF-DIAG [PAST]”.
6. Touch “BACK” key of CONSULT-III to return to User mode from Diagnosis mode.
7. Turn ignition switch OFF and then turn off and disconnect CONSULT-III.
8. Go to SRC-11, "
SRS Operation Check".
DIAGNOSTIC PROCEDURE 4
Check SRS Repair History
1.CONSIDER POSSIBILITY THAT SELF-DIAGNOSTIC RESULT WAS NOT ERASED AFTER REPAIR
Check repair history of the SRS.
Have any previous repairs been made to the SRS?
Yes >> Self-diagnostic result “SELF-DIAG [PAST]” (previously stored in the memory) might not be erased
after repair. Perform DIAGNOSTIC PROCEDURE 3. Refer to SRC-13, "
Self-Diagnosis Function
(Without CONSULT-III)".
No >> Perform DIAGNOSTIC PROCEDURE 2. Refer to SRC-11, "
SRS Operation Check".
