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

  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 (rh).
  3.  connect the negative () terminal cable to the battery, and wait at least for 2 seconds.
  4.  turn the ignition switch to on.
  5. for the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (rh), measure the voltage between sfr+ and body ground.

    Ok: voltage: below 1 v
