Toyota Corolla (E120): Inspection procedure

1 Check p/t squib(lh) circuit(airbag sensor assy center – front seat outer belt 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 seat belt pretensioner (lh).
