Short in Squib Circuit or Front Airbag Sensor Circuit to Ground

^CIRCUIT DESCRIPTION ---

The squib circuit consists of the center airbag sensor assembly, spiral cable and the steering wheel pad (squib). It causes the airbag to deploy when the airbag deployment conditions are satisfied. The front airbag sensor detects the deceleration force in a frontal collision and is located in the front fender on the left and right sides.

For details of the function of each component, see FUNCTION OF COMPONENTS on page AB-7.

Diagnostic code 11 is recorded when occurrence of ground short is detected in the squib circuit or front airbag sensor circuit.

Code No.

Diagnosis

Preparation.

2

Check front airbag sensor circuit. (Measure resistance between terminals +SR and -SR, +SL and -SL of center airbag sensor assembly connector.)

OK

3

Check front ai rbag sensor circuit. (Measure resistance between terminals + SR, +SL of center airbag sensor assembly connector and body ground.)

J OK

4

Check squib circuit.

OK

5

Check center airbag sensor assembly.

OK

6

Check squib.

OK

From the results of the above inspection, the malfunctioning part can now be considered normal. To make sure of this, use the simulation method to check.

Repair or replace harness or connector between center airbag sensor assembly and front airbag sensor (See page AB-21).
