SRC-126

< COMPONENT DIAGNOSIS >

B1212, B1213, B1214 RH1 SAT-SENS

B1212, B1213, B1214 RH1 SAT-SENS

Description

INFOID:0000000003941406

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 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 Logic

INFOID:0000000003941407

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAG RESULT

 With CONSULT-III

1.

Turn ignition switch ON.

2.

Perform “AIR BAG” Self Diagnostic Result.

 Without CONSULT-III

1.

Turn ignition switch ON.

2.

Check the air bag warning lamp status. Refer to 

SRC-10, "Air Bag Warning Lamp Diagnosis"

.

YES

>> Refer to 

SRC-126, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000003941408

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.
