SRC-26

< COMPONENT DIAGNOSIS >

B1035, B1036 CRASH ZONE SEN

B1035, B1036 CRASH ZONE SEN

Description

INFOID:0000000003813951

Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level caused by
vehicle frontal collision.

OPERATION

When air bag diagnosis sensor unit defines both signal voltage of the “G” sensor and the safing algorithm to
be that of collision which exceeds a specified level, the driving circuit switches on and feeds the electric ignitor
of both driver and passenger air bags and pre-tensioner seat belts.

STRUCTURE

Integrated type of the “G” sensor element for frontal collision with output terminals for signal voltage.

INSTALLATION

Crash zone sensor is installed on the radiator core support assembly with fixed nuts.

DTC Logic

INFOID:0000000003813952

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAG RESULT

 With CONSULT-III
