Toyota Corolla Repair Manual: Inspection procedure
1 Check wire harness(airbag sensor assy center – front seat inner belt 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 inner belt assy (lh).
- for the connector (on the airbag sensor assy center side)
between the airbag sensor assy center and the front seat
inner belt assy (lh), measure the resistance between
lbe+ and body ground.
Ok: resistance: 1 mw or higher
2 Check wire harness(airbag sensor assy center – front seat inner belt assy lh)
- Connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
- turn the ignition switch to on.
- for the connector (on the airbag sensor assy center side)
between the airbag sensor assy center and the front seat
inner belt assy (lh), measure the voltage between lbe+
and body ground.
Ok: voltage: below 1 v
3 Check front seat inner belt assy lh
- Turn the ignition switch to lock.
- disconnect the negative (–) terminal cable from the battery, and wait at least for 90 seconds.
- connect the connector of the front seat inner belt assy (lh).
- unlock the seat belt for the front driver’s seat.
- for the connector (on the airbag sensor assy center side),
measure the resistance between lbe+ and body ground.
Ok: resistance: 1.0 Kw – 1.6 KΩ
4 Check front seat inner belt assy lh
- Lock the seat belt for the front driver’s seat.
- for the connector (on the airbag sensor assy center side),
measure the resistance between lbe+ and body ground.
Ok: resistance: 100 w – 500 Ω
5 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.

- 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 b0126/b0127/27 is not output.
Hint
: codes other than code b0126/b0127/27 may be output at this time, but they are not relevant to this check.
