B1037, B1039, B1041 CRASH ZONE SENS1

Description

INFOID:0000000005513523

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.

Description

INFOID:0000000005513526

DTC B1042, B1043, B1044, B1045, B1046, B1047 DIAGNOSIS SENSOR UNIT

Detects the whole SRS electrical system 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 electro-diagnosis tester CONSULT-III.

OPERATION

It detects a shock that exceeds specified level and monitors such systems as the driver and passenger air
bag, side air bag, curtain air bag, pre-tensioner seat belts and Occupant Classification System (OCS) operate
properly. 

STRUCTURE

It contains the “G” sensors for both for frontal and side collisions and spare battery function in case of main
battery damage in collision.

INSTALLATION

Air bag diagnosis sensor unit is installed under the center console with fixed bolts.
