Toyota Corolla (E120): 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).
- 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 body ground.
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 b0117/45 is not output.
Hint
: codes other than code b0117/45 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 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 b0117/45 is not output.
Hint
: codes other than code b0117/45 may be output at this time, but they are not relevant to this check.

Blind Spot Monitor operation
■ Objects that can be detected while driving
The Blind Spot Monitor uses rear side radar sensors to detect the following
vehicles traveling in adjacent lanes and advises the driver of
the presence of such vehicles via the indicators on the outside rear
view mirrors.
Vehicles that are traveling ...
Inspection procedure
1 Input signal check
See the input signal check on page 05–745.
check the indicator light when the clutch pedal is depressed.
Ok:
the indicator light goes off when the clutch pedal is
depressed.
2 Inspect terminal voltage(d)
Turn the ignition switch to on.

RCTA function
■ Operation of the RCTA function
The RCTA function uses rear side radar sensors to detect vehicles
approaching from the right or left at the rear of the vehicle and alerts
the driver of the presence of such vehicles by flashing the outside
rear view mirror indicators and sounding a buzzer.
