B1113 B1114

Description
DTC Logic
Diagnosis Procedure

Description

Main “G” sensor generates signal voltage, when it detects deceleration beyond the specified level by vehicle side 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 the front side air bag and side curtain air bag.

STRUCTURE

Integrated type of the “G” sensor element for side collision with output terminals for signal voltage.

INSTALLATION

RH satellite sensor is installed at the underside of center pillar with fixed nuts.

DTC CONFIRMATION PROCEDURE

1.CHECK SELF-DIAG RESULT

Diagnosis Procedure

■ WARNING ■

Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait at least 3 minutes. (To discharge backup capacitor.)

Never use unspecified tester or other measuring device.

1.CHECK HARNESS CONNECTOR

2.CHECK WIRING HARNESS

3.REPLACE SATELLITE SENSOR

4.REPLACE AIR BAG DIAGNOSIS SENSOR UNIT
