FUNCTION DIAGNOSIS
SRS AIR BAG SYSTEM
SRS ConfigurationINFOID:0000000001396347
The air bag deploys if the air bag diagnosis sensor unit is activated while the ignition switch is in the ON or
START position.
The collision modes for which supplemental restraint systems are activated are different among the SRS sys-
tems. For example, the driver air bag module, front passenger air bag module and front seat belt pre-tension-
ers are activated in a frontal collision but not in a side collision.
SRS configurations for some collision modes are as follows:

DIAGNOSTIC PROCEDURE 2
1. Connect CONSULT-III.
2. Diagnostic code is displayed on "SELF-DIAG [CURRENT]".
If no malfunction is detected on "SELF-DIAG [CURRENT]", but malfunction is detected in "SRS Operation
Check" using the "AIR BAG" warning lamp, the following cases may exist:
 "SELF-DIAG [PAST]" memory might not be erased.
 The SRS system malfunctions intermittently.
Perform DIAGNOSTIC PROCEDURE 4. Refer to SRC-13, "

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.
