B1033, B1034 CRASH ZONE SEN

B1033, B1034 CRASH ZONE SEN

Description

INFOID:0000000005513718

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.

Diagnosis Procedure

INFOID:0000000005513720

With CONSULT-lll

WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3

minutes. (To discharge backup capacitor.)

• Do not use unspecified tester or other measuring device.

DIAGNOSTIC PROCEDURE

1.

CHECK HARNESS CONNECTOR

Check the connection of harness connector.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace harness connectors.

2.

CHECK WIRING HARNESS

Check the wiring harness externals.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace wiring harness.

3.

CHECK CRASH ZONE SENSOR

1.

Replace crash zone sensor.

2.

Check the screen of CONSULT-lll.

Is the inspection result normal?

YES

>> INSPECTION END.

NO

>> Check the intermittent incident. Refer to 

GI-39, "Intermittent Incident"
