Toyota Corolla (E120): 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)

- 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.

Inspection procedure
Hint:
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, it is
useful for determining whether
the vehicle was running or stopped, the engine was warmed up or not, the ...
Initialization
1. Reset memory
Caution:
perform the reset memory (at initialization) when replacing the automatic
transaxle assy, engine
assy or ecm.
Notice:
hand–held tester only
Turn the ignition switch off.
connect the hand–held tester to the dlc3.
turn the ignition switch to th ...
On–vehicle inspection
1. Inspection throttle body idle speed control valve assy
Notice:
it is impossible to check the resister value and the operation
of isc valve by itself, because the isc valve
has an ic circuit inside it, which transforms the duty
signal from the ecm to the derive signal.
After check ...
