After a malfunction is repaired, turn the ignition switch OFF for at least one second, then turn ignition switch
ON. Diagnosis mode returns to the user mode. At that time the self-diagnosis result is cleared.
CONSULT-III FunctionINFOID:0000000003813935
HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-III
From User Mode to Diagnosis Mode
After selecting “AIR BAG” on the “SELECT SYSTEM” screen, User mode automatically changes to Diagnosis
mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch “BACK” key of CONSULT-III until “SELECT SYSTEM”
appears, then Diagnosis mode automatically changes to User mode.
DIAGNOSIS MODE FOR CONSULT-III
 “SELF-DIAG [CURRENT]”
Current self-diagnosis results (also indicated with the number of air bag warning lamp blinks in Diagnosis
mode) are displayed on CONSULT-III screen in real time. This refers to a malfunctioning part requiring
repairs.
 “SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on CONSULT-III screen. The stored results
are not erased until memory erasing is executed.
 “TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed
on CONSULT-III screen.
 “DISCRIMINATED NO.”
The air bag diagnosis sensor unit for each vehicle model has its own individual classification number. This
number is displayed on CONSULT-III screen. When replacing the air bag diagnosis sensor unit, refer to the
part number for the compatibility. After installation, replacement with a correct unit can be checked by con-
firming this classification number on CONSULT-III screen.
After repair, check that the discriminated number of air bag diagnosis sensor unit installed to vehicle is the
same. Refer to SR-22, "
Exploded View".
HOW TO ERASE SELF-DIAGNOSTIC RESULTS
 “SELF-DIAG [CURRENT]”
A current self-diagnosis result is displayed on CONSULT-III screen in real time.
After the malfunction is repaired completely, no malfunction is detected on “SELF-DIAG [CURRENT]”.
 “SELF-DIAG [PAST]”
Return to “SELF-DIAG [CURRENT]” CONSULT-III screen by touching “BACK” key of CONSULT-III and
select “SELF-DIAG [CURRENT]” in SELECT DIAG MODE. Touch “ERASE” in “SELF-DIAG [CURRENT]”
mode.
NOTE:
If the memory of the malfunction in “SELF-DIAG [PAST]” is not erased, the user mode shows the system
malfunction by illuminating the warning lamp even if the malfunction is repaired completely.
 “TROUBLE DIAG RECORD”
The memory of “TROUBLE DIAG RECORD” cannot be erased.

B1049 DRIVER AIRBAG MODULE
B1049 DRIVER AIRBAG MODULE
DescriptionINFOID:0000000003813957
For driver air bag module, crash is judged by main “G” sensor output signal and safing algorithm in front direc-
tion.
OPERATION
In case of frontal collision whose acceleration exceeds the specified level, the ignition materials are ignited by
electric ignition system. The system burns the gas generating materials resulting in a chemical reaction. This
generates hot gases that flow into the air bag through a filter and expand the bag.
STRUCTURE
Driver air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
Driver air bag module is installed on the center of steering wheel with fixed bolts.
DTC LogicINFOID:0000000003813958
DTC CONFIRMATION PROCEDURE
1.CHECK SELF-DIAG RESULT
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “AIR BAG” Self Diagnostic Result.
Without CONSULT-III
1. Turn ignition switch ON.
2. Check the air bag warning lamp status. Refer to SRC-10, "
Air Bag Warning Lamp Diagnosis".
NOTE:
SRS does not enter Diagnosis mode if no malfunction is detected in User mode.
Is malfunctioning part detected?
YES >> Refer to SRC-32, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003813959
WARNING:
With CONSULT-III
 Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3
minutes. (To discharge backup capacitor.)
 Never use unspecified tester or other measuring device.
