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.
- connect the negative (–) terminal cable to the battery,
and wait at least for 2 seconds.
- turn the ignition switch to on.
- for the orange connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the voltage between d+ and body
ground.
Ok:
voltage: below 1 v


2 Check air bag sensor assy center

- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery,
and wait at least for 90 seconds.
- connect the connector to the airbag sensor assy center.
- using a service wire, connect d+ and d– of the orange
connector (on the spiral cable sub–assy side) between
the horn button assy and the spiral cable sub–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 60 seconds.
- check the dtc .
Ok:
dtc b0103/12 is not output.
Hint
:
codes other than code b0103/12 may be output at this time, but
they are not relevant to this check.


3 Check d squib
Sst 09843–18040

Hint
:
codes other than code b0103/12 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
5 Check instrument panel wire(airbag sensor assy center – spiral
cable sub–assy)

- Turn the ignition switch to lock.
- disconnect the connectors of the instrument panel wire.
- turn the ignition switch to on.
- for the connector (on the spiral cable sub–assy side) between
the airbag sensor assy center and the spiral cable
sub–assy, measure the voltage between d+ and body
ground.
Ok:
voltage: below 1 v


6 Check spiral cable sub–assy

- For the orange connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the voltage between d+ and body
ground.
Ok:
voltage: below 1 v


7 Use simulation method to check


Replace all srs components including the wire harness
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.
