Toyota Corolla Repair Manual: Inspection procedure
1 Check p/t squib(rh) circuit(airbag sensor assy center – front
seat outer belt 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 seat belt pretensioner (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 seat belt pretensioner side) between
the airbag sensor assy center and the seat belt pretensioner
(rh), measure the voltage between pr+ and
body ground.
Ok:
voltage: below 1v
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 pr+ and pr– of the connector
(on the seat belt pretensioner side) between the
airbag sensor assy center and the seat belt pretensioner
(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 b0133/62 is not output.
Hint
:
codes other than code b0133/62 may be output at this time, but
they are not relevant to this check.
3 Check p/t 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 seat belt pretensioner (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 b0133/62 is not output.
Hint
:
codes other than code b0133/62 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/t squib (rh) circuit consists of the airbag sensor assy center and seat
belt pretensioner (rh).
It causes the srs to deploy when the srs deployment conditions are satisfied.

Foamed material application areas
If an increase in temperature or other condition damages the foamed material
when repairing or replacing the panel,
fill in the insufficient areas with urethane foam. The following illustration
shows the areas for one side, but the
foamed material must be applied equally to both the left and r ...
