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 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
