Toyota Corolla Repair Manual: 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).
- 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 resistance between sfr+
and body ground.
Ok: resistance: 1 mΩ 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 sfr+ and sfr– of the connector (on the 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 b0112/41 is not output.
Hint
: codes other than code b0112/41 may be output at this time, but they are not relevant to this check.
3 Check side squib(rh)
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 (rh) 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 b0112/41 is not output.
Hint
: codes other than code b0112/41 may be output at this time, but they are not relevant to this check.
4 Use simulation method to check
Replace all srs components including the wire harness
Circuit description
The side squib (rh) circuit consists of the airbag sensor assy center and
front seat airbag assy (rh).
It causes the srs to deploy when the srs deployment conditions are satisfied.

Other materials:
Fuel pump shut off system
To minimize the risk of fuel leakage when the engine stalls or when an airbag
inflates upon collision, the fuel pump shut off system stops the supply of fuel
to the engine.
Follow the procedure below to restart the engine after the system is activated.
