Toyota Corolla Repair Manual: 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 connector 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 p2+ 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 p2+ and p2– 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 b1188/56 is not output.
Hint
:
codes other than code b1188/56 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
The p squib (2nd step) circuit consists of the airbag sensor assy center and
instrument panel passenger
airbag assy.
It causes the srs to deploy when the srs deployment conditions are satisfied. ...

Inspection procedure
Hint:
hand–held tester only:
narrowing down the trouble area is possible by performing ”a/f control” active
test (heated oxygen
sensor or other trouble areas can be distinguished).
Perform active test using hand–held tester (a/f control).
Hint:
”a/f control” is the active test which cha ...
