Toyota Corolla (E120) 2002–2008 Repair Manual / Diagnostics / Supplemental restraint system / Short in d squib circuit / Inspection procedure
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 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
