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).
  3.  for the connector (on the seat belt pretensioner side) between the airbag sensor assy center and the seat belt pretensioner (lh), measure the resistance between pl+ and pl.

    Ok: resistance: below 1 Ω

2 Check air bag sensor assy center
