Inspection Procedure

| Preparation

Check

Ciulion

(1) Disconnect battery negative (-) terminal cable, and wait at least 20 seconds.

(2) Remove steering wheel pad (See page AB-15).

Ciulion

When storing steering wheel pad, keep upper surface of the pad facing upward.

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

Code 12

(1) Turn ignition switch LOCK.

(2) Disconnect negative (-) terminal cable from bat tery.

(3) Connect connector to center airbag sensor as sembly.

(4) Using a service wire, connect D+ and D- on spi ral cable side of connector between spiral cable and steering wheel pad.

(5) Connect negative (-) terminal cable to battery, and wait at least 2 seconds.

(1) Turn ignition switch ACC or ON, and wait at least

20 seconds.

(2) Using SST, connect terminals Tc and E1 of check connector. SST 09843-18020

(3) Check diagnostic code. Diagnostic code 12 is not output.

Codes other than code 12 may be output at this time, but this is not relevant to this check

(1) Turn ignition switch LOCK.

(2) Disconnect connector between center airbag sensor assembly and spiral cable.

(3) Turn ignition switch ON.

Measure voltage at D+ on spiral cable side of connector between spiral cable and steering wheel pad.

Voltage: 0 V

NG ': Repair or replace spiral cable.

Repair or replace harness or connector between center airbag sensor assembly and spiral cable.

Diag. Code

Short in Squib Circuit (Between D+" Wire Harness and D- Wire Harness)

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.

For details of the function of each component, see FUNCTION OF COMPONENTS on page AB-7. Diagnostic code 13 is recorded when a short is detected in the D+ wire harness and D- wire harness of the squib circuit.

Code. No.

Diagnosis

13

• Short circuit between D+ wire harness and D- wire harness of squib.

• Squib malfunction.

• Spiral cable malfunction.

• Center airbag sensor assembly malfunction.
