B1052 DRIVER AIRBAG MODULE
B1052 DRIVER AIRBAG MODULE
DescriptionINFOID:0000000003813966
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:0000000003813967
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-38, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003813968
WARNING:
 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.

DescriptionINFOID:0000000003813969
Check the whole SRS and displays the malfunction either by illuminating or blinking the air bag warning lamp
in the combination meter. Malfunctioning part can be detected by on board self-diagnosis system and CON-
SULT-III.
OPERATION
It detects a shock that exceeds a specified level and monitors whether the driver and passenger air bags, front
side air bag, side curtain air bag and pre-tensioner seat belts operate normally.
STRUCTURE
It contains the “G” sensors for both frontal and side collisions and spare battery function in case of main bat-
tery damage in collision.
INSTALLATION
Air bag diagnosis sensor unit is installed under the center console with fixed bolts.
