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.)

Cttntet Airbag Seni&t Assembly

Disconnect center airbag sensor assembly connector.

Measure resistance between terminals +SR and-SR, +SL and -SL of harness side connector of center airbag sensor assembly.

m Resistance: 755Q - 885Q

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

Measure resistance between terminals +SR, +SL of harness side connector of center airbag sensor assembly and body ground.

E3 Resistance: oo q

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

Check squib circuit.
