Toyota Corolla Repair Manual: Circuit description
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 p–.
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 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 b0106/54 is not output.
Hint
: codes other than code b0106/54 may be output at this time, but they are not relevant to this check.

- 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 b0106/54 is not output.
Hint
: codes other than code b0106/54 may be output at this time, but they are not relevant to this check.
