B1082 PRE-TEN FRONT RH
B1082 PRE-TEN FRONT RH
DescriptionINFOID:0000000003813990
For front RH seat belt pre-tensioner, crash is judged by main “G” sensor output signal and safing algorithm in
front direction.
OPERATION
In the case of a frontal collision that exceeds specified impact level, the air bag diagnosis sensor unit detects
the deceleration caused by collision. It restrains the passenger with seat belt easing the stress on passengers
chest with load limiter.
STRUCTURE
The restraint system for front seat occupant consists of the pre-tensioner mechanism and load limiter mecha-
nism.
INSTALLATION
Front RH seat belt pre-tensioner is installed on the underside of center pillar with fixed nuts.
DTC LogicINFOID:0000000003813991
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-54, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003813992
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?
