Toyota Corolla (E120): 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 horn button assy and the airbag sensor assy center.
- 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: below 1 Ω


2 Check air bag sensor assy center
Sst 09843–18040

- 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 20 seconds.
- check the dtc .
Ok: dtc b0101/14 is not output.
Hint
: codes other than code b0101/14 may be output at this time, but they are not relevant to this check.


3 Check d squib

4 Check instrument panel wire(airbag sensor assy center – spiral cable sub–assy)

- Disconnect the connector of the instrument panel wire.
- 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: below 1 Ω


5 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 resistance between d+ and d–.
Ok: resistance: below 1 Ω
