B1035 CRASH ZONE SEN
Description
INFOID:0000000001069780
DTC B1035 [COMM FAIL] CRASH ZONE SENSOR
Main “G” sensor that generates signal voltage, when it detects deceleration beyond the specified level caused
by vehicle frontal collision.
OPERATION
When ACU defines both signal voltage of the “G” sensor and the safing sensor to be that of collision which
exceeds specified level, the driving circuit switches on and feed the electric ignitor of both driver and passen-
ger 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.
