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.
- 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 instrument panel passenger airbag
assy side) between the airbag sensor assy center
and the instrument panel passenger airbag assy, measure
the voltage between p+ and body ground.
Ok: voltage: below 1 v
2 Check air bag sensor assy center
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 connector to the airbag sensor assy center.
- using a service wire, connect p+ and p– of the connector (on the instrument panel passenger airbag assy side) between the airbag sensor assy center and the instrument panel passenger airbag assy.
- 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 b0108/52 is not output.
Hint
: codes other than code b0108/52 may be output at this time, but they are not relevant to this check.

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.
Dtc b0110/43 is recorded when a short is detected in the side squib (rh)
circuit.
