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 connectors between the airbag sensor
assy center and the instrument panel passenger airbag
assy.
- 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 resistance between p+ and body ground.
Ok:
resistance: 1 mΩ or higher


2 Check air bag sensor assy center
Sst 09843–18040

- Connect the connector to the airbag sensor assy center.
- using a service wire, connect p+ and p– of the connector
(on the instrument panel passenger airbag assy side) 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, and wait at least for 20 seconds.
- clear the dtc stored in memory .
- turn the ignition switch to lock, and wait at least for 20
seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok:
dtc b0107/51 is not output.
Hint
:
codes other than code b0107/51 may be output at this time, but
they are not relevant to this check.


3 Check p squib
Sst 09843–18040
- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery,
and wait at least for 90 seconds.
- connect the instrument panel passenger airbag assy
connector.
- connect the negative (–) terminal cable to the battery,
and wait at least for 2 seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- clear the dtc stored in memory .
- turn the ignition switch to lock, and wait at least for 20
seconds.
- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok:
dtc b0107/51 is not output.
Hint:
codes other than code b0107/51 may be output at this time, but
they are not relevant to this check.


4 Use simulation method to check


Replace all srs components including the wire harness
The p squib 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.
