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).
- 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: 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 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 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 b0116/48 is not output.
Hint
:
codes other than code b0116/48 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 b0116/48 is not output.
Hint
:
codes other than code b0116/48 may be output at this time, but
they are not relevant to this check.


Use simulation method to check
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.

Inspection procedure
Hint:
if dtcs besides misfire are memorized simultaneously, first perform
the troubleshooting for them.
Read freeze frame data using the hand-held tester or the obd ii scan
tool. Freeze frame data records
the engine conditions when a malfunction is detected. When troubleshooting,

Circuit description
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.
Dtc b0130/63 is recorded when a short is detected in the p/t squib (rh) circuit.

Notice:
wash the brake fluid off immediately if it comes into contact with any painted
surface.
Hint:
if any work is done on the brake system or if air in the brake lines is
suspected, bleed the air from the system.
