Toyota Corolla Repair Manual: Inspection procedure
1 Check side squib(lh) circuit(airbag sensor assy center – front seat airbag assy lh)
- 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 front seat airbag assy (lh).
- release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat airbag assy (lh) .
- for the connector (on the front seat airbag assy side) between
the airbag sensor assy center and the front seat
airbag assy (lh), measure the resistance between sfl+
and sfl–.
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.
- using a service wire, connect sfl+ and sfl– of the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (lh).
- 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 b0115/47 is not output.
Hint
: codes other than code b0115/47 may be output at this time, but they are not relevant to this check.
3 Check side squib(lh)
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 front seat airbag assy (lh) connector.
- 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 b0115/47 is not output.
Hint
: codes other than code b0115/47 may be output at this time, but they are not relevant to this check.
Use simulation method to check
