Toyota Corolla Repair Manual: Inspection procedure
1 Check p squib circuit(airbag sensor assy center – instrument
panel passenger airbag assy)
- Disconnect the negative (–) terminal cable from the battery,
and wait at least for 90 seconds.
- disconnect the connector between the airbag sensor
assy center and the instrument panel passenger airbag
assy.
- connect the negative (–) terminal cable to the battery,
and wait at least for 2 seconds.
- turn the ignition switch to on.
- for the connector (on the instrument panel passenger airbag
assy side) between the airbag sensor assy center
and the instrument panel passenger airbag assy, measure
the voltage between p2+ and body ground.
Ok:
voltage: below 1 v
2 Check air bag sensor assy center
Sst 09843–18040
- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery,

4 Use simulation method to check
Replace all srs components including the wire harness
The p squib (2nd step) circuit consists of the airbag sensor assy center and
instrument panel passenger
airbag assy.
It causes the srs to deploy when the srs deployment conditions are satisfied. ...
