Toyota Corolla (E120): Inspection procedure
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.
- release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) 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 p2+ and p2–.
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 b1185/57 is not output.
Hint
: codes other than code b1185/57 may be output at this time, but they are not relevant to this check.
