Wiring diagram
Inspection procedure
Hint:
- Perform the simulation method by selecting the "check mode" (signal
check) with the intelligent
tester (see page rs-52).
- After selecting the "check mode" (signal check), perform the simulation
method by wiggling each
connector of the airbag system or driving the vehicle on a city or rough
road (see page rs-52).
- Check curtain shield airbag assembly rh (front passenger side curtain
shield squib)
- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Disconnect the connectors from the curtain shield airbag
rh.
- Connect the white wire side of sst to connector c.
Caution:
Never connect a tester to the curtain shield airbag
rh (front passenger side curtain shield squib) for
measurement, as this may lead to a serious injury
due to airbag deployment.
Notice:
- Do not forcibly insert sst into the terminals of the
connector when connecting.
- Insert sst straight into the terminals of the
connector.
Sst 09843-18060

- Turn the ignition switch off.
- Disconnect the cable from the negative (-) battery
terminal, and wait for at least 90 seconds.
- Measure the resistance of the wire harness side
connector.
