Toyota Corolla Repair Manual: Inspection procedure
1 Check p/t squib(lh) circuit(airbag sensor assy center – front seat outer belt assy lh)
- 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 (lh).
- for the connector (on the seat belt pretensioner side) between
the airbag sensor assy center and the seat belt pretensioner
(lh), measure the resistance between pl+ and
pl–.
Ok: resistance: below 1 Ω
2 Check air bag sensor assy center
Sst 09843–18040
- Connect the connector to the airbag sensor assy center.
- using a service wire, connect pl+ and pl– of the connector (on the seat belt pretensioner side) between the airbag sensor assy center and the seat belt pretensioner (lh).
- 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 b0136/74 is not output.
Hint
: codes other than code b0136/74 may be output at this time, but they are not relevant to this check.
3 Check p/t squib (lh)
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 (lh) 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 b0136/74 is not output.
Hint
: codes other than code b0136/74 may be output at this time, but they are not relevant to this check.
Use simulation method to check
Circuit description
The p/t squib circuit (lh) consists of the airbag sensor assy center and seat
belt pretensioner (lh).
It causes the srs to deploy when the srs deployment conditions are satisfied.

Circuit description
The d squib circuit consists of the airbag sensor assy center, spiral cable
sub–assy and horn button assy.
It causes the srs to deploy when the srs deployment conditions are satisfied.
Dtc b1180/17 is recorded when a short is detected in the d squib circuit (2nd
step).
