Toyota Corolla Repair Manual: Inspection procedure
1 Check side squib(lh) circuit(airbag sensor assy center – front seat airbag 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 front seat airbag assy (lh).
- release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) between the airbag sensor assy center and the front seat airbag assy (lh) .
- for the connector (on the front seat airbag assy side) between
the airbag sensor assy center and the front seat
airbag assy (lh), measure the resistance between sfl+
and sfl–.
Ok: resistance: 1 mw or higher
2 Check air bag sensor assy center
Sst 09843–18040
- Connect the connector to the airbag sensor assy center.
- using a service wire, connect sfl+ and sfl– of the connector (on the front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (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 b0115/47 is not output.
Hint
: codes other than code b0115/47 may be output at this time, but they are not relevant to this check.
3 Check side 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 front seat airbag assy (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 b0115/47 is not output.
Hint
: codes other than code b0115/47 may be output at this time, but they are not relevant to this check.
Use simulation method to check
Circuit description
The side squib (lh) circuit consists of the airbag sensor assy center and
front seat airbag assy (lh).
It causes the srs to deploy when the srs deployment conditions are satisfied.

Circuit description
The actuator motor is operated by signals from the cruise control ecu assy.
Acceleration and deceleration
signals are transmitted by changes in the duty ratio (see below).
Duty ratio:
the duty ratio is the ratio of the period of continuity in one cycle. For
example, if a is the period of co ...

System description
The ecm uses signals from the vehicle speed sensor and crankshaft position
sensor to detect the actual
gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedu ...
