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 black connector (on the spiral cable sub–assy
side ) between the horn button assy and the spiral cable
sub–assy, measure the resistance between d2+ and
d2–.
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 b1180/17 is not output.
Hint
: codes other than code b1180/17 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 b1180/17 is not output.
Hint
: codes other than code b1180/17 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 d2+ and
d2–.
Ok: resistance: 1 mw 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 black connector (on the spiral cable sub–assy
side) between the horn button assy and the spiral cable
sub–assy, measure the resistance between d2+ and
d2–.
Ok: resistance: 1 mw or higher
Use simulation method to check
Circuit description
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.

Inspection procedure
Hint:
read freeze frame data using the hand-held tester or the obd ii scan tool.
Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, it is
useful for determining whether
the vehicle was running or stopped, the engine was warmed up or not, the ...
