Toyota Corolla Repair Manual: Inspection procedure
1 Check d squib circuit(airbag sensor assy center – horn button
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 horn button assy.
- release the airbag activation prevention mechanism of the connector (on
the airbag sensor assy center side) between the airbag sensor assy center
and the spiral cable sub–assy .
- for the connector (on the spiral cable sub–assy side) between
the horn button assy and the spiral cable sub–assy,
measure the resistance between d+ and d–.
Ok:
resistance: 1 mw or higher


2 Check air bag sensor assy center
Sst 09843–18040

- Connect the connector to the airbag sensor assy center.
- 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 b0100/13 is not output.
Hint
:
codes other than code b0100/13 may be output at this time, but
they are not relevant to this check.


3 Check d 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 horn button assy connectors.
- 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 b0100/13 is not output.
Hint:
codes other than code b0100/13 may be output at this time, but
they are not relevant to this check.


Use simulation method to check
4 Check instrument panel wire(airbag sensor assy center – spiral
cable sub–assy)

- Disconnect the connector of the instrument panel wire.
- release the airbag activation prevention mechanism of the connector (on
the airbag sensor assy center side) between the airbag sensor assy center
and the spiral cable sub–assy .
- for the connector (on the spiral cable sub–assy side) between
the airbag sensor assy center and the spiral cable
sub–assy, measure the resistance between d+ and d–.
Ok:
resistance: 1 mΩ or higher


5 Check spiral cable sub–assy

- Release the airbag activation prevention mechanism of the spiral cable
sub–assy connector on the airbag sensor assy center side .
- for the orange connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the resistance between d+ and d–.
Ok:
resistance: 1 mΩ or higher


Use simulation method to check
The d squib circuit consists of the airbag sensor assy center, spiral cable
sub–assy and horn button assy.
It causes the srs to deploy when the srs deployment conditions are satisfied.
