Toyota Corolla (E120): Inspection procedure
1 Check side squib(rh) circuit(airbag sensor assy center – front seat airbag assy rh)

- 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 (rh).
- 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 front seat airbag assy side) between
the airbag sensor assy center and the front seat
airbag assy (rh), measure the voltage between sfr+
and body ground.
Ok: voltage: below 1 v


2 Check air bag sensor assy center

- using a service wire, connect sfr+ and sfr– of the connector (on the front front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (rh).
- 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 b0113/42 is not output.
Hint
: codes other than code b0113/42 may be output at this time, but they are not relevant to this check.
