6  Check squib.

Center Airbag
Sensor Assembly

Spiral
Cable

Steering Wheel
Pad (Squib)

ACC    ON

E₁        Tc

Code 11

AM025
AM018
AB018
AB024

OK

P (1) Turn ignition switch LOCK.
(2) Disconnect battery negative (−) terminal cable, and wait at least 20 seconds.
(3) Connect steering wheel pad (squib) connector.
(4) Connect negative (−) terminal cable to battery, and wait at least 2 seconds.

C (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.

OK  Diagnostic code 11 is not output.

Hint Codes other than code 11 may be output at this time, but this is not relevant to this check.

NG  Replace steering wheel pad.

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.

7  Check front airbag sensor.

+A

+S

−S         −A

A30034

OK

P  Disconnect front airbag sensor connector.

C  Measure resistance between each terminal of front airbag sensor.

OK
Terminal           Resistance
−S — ⊕A         755 Ω — 885 Ω
⊕S — ⊖S              ∞
⊕S — ⊕A         Less than 1 Ω

Notice
• Do not touch ohmmeter probes strongly against terminals of front airbag sensor.
• Make sure the front airbag sensor connector is properly connected.

NG  Replace front airbag sensor.

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