Toyota Corolla Repair Manual: Inspection procedure

1 Check d squib circuit(airbag sensor assy center horn button assy)

  1. Disconnect the negative () terminal cable from the battery, and wait at least for 90 seconds.
  2.  disconnect the connectors between the airbag sensor assy center and the horn button assy.
  3. release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the spiral cable subassy .
  4.  for the black connector (on the spiral cable subassy side ) between the horn button assy and the spiral cable subassy, measure the resistance between d2+ and d2.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center
