Toyota Corolla Repair Manual: Inspection procedure

1 Check side squib(lh) circuit(airbag sensor assy center front seat airbag assy lh)

  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 front seat airbag assy (lh).
  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 front seat airbag assy (lh) .
  4.  for the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh), measure the resistance between sfl+ and sfl.

    Ok: resistance: 1 mw or higher

2 Check air bag sensor assy center
