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.

CAUTION:

• Before servicing, turn ignition switch OFF, disconnect both battery terminals and wait at least 3 min-

utes. (To discharge backup capacitor.)

• Do not use unspecified tester or other measuring device. 

DIAGNOSTIC PROCEDURE

1.

CHECK HARNESS CONNECTOR

Are connections of harness connectors and terminals correct?

YES

>> GO TO 2.

NO

>> Repair or replace harness connectors.

2.

CHECK WIRING HARNESS

Is the outside of wiring harness normal, without any damage?

YES

>> GO TO 3.

NO

>> Replace wiring harness.

3.

CHECK CRASH ZONE SENSOR

Is crash zone sensor displayed on CONSULT-III?

YES

>> Replace crash zone sensor.

NO

>> Replace diagnosis sensor unit (ACU).

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 watches such systems as the driver and passenger air bag,
side air bag, curtain air bag, pre-tensioner seat belts operate properly. 

STRUCTURE

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

INSTALLATION

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