B1136 SIDE MODULE LH
B1136 SIDE MODULE LH
DescriptionINFOID:0000000003814047
For front LH side air bag module, crash is judged by main “G” sensor output signal (left side: LH satellite sen-
sor, right side: RH satellite sensor) and safing algorithm (in air bag diagnosis sensor unit).
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
Front LH side air bag module mainly consists of air bag and inflator which inflates air bag.
INSTALLATION
Front LH side air bag module is installed on the side of front seatback with fixed nuts.
DTC LogicINFOID:0000000003814048
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-94, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003814049
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.
1.CHECK HARNESS CONNECTOR
Check the harness connector.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace harness connector.
2.CHECK WIRING HARNESS
Check the wiring harness externals.
Is the inspection result normal?
YES >> GO TO 3.

DescriptionINFOID:0000000003814053
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.
