Toyota Corolla (E120): Inspection procedure
1 Check side squib(rh) circuit(airbag sensor assy center – front seat airbag assy rh)
- Disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- disconnect the connectors between the airbag sensor assy center and the front seat airbag assy (rh).
- 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 resistance between sfr+
and body ground.
Ok: resistance: 1 mΩ or higher
2 Check air bag sensor assy center
