Description

INFOID:0000000005513517

DTC B1033, B1034 [UNIT FAIL] CRASH ZONE SENSOR

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

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.
