Toyota Corolla Repair Manual: Inspection procedure
1 Check side squib(rh) circuit(airbag sensor assy center – front seat airbag assy rh)
- 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 (rh).
- connect the negative (–) terminal cable to the battery, and wait at least for 2 seconds.
- turn the ignition switch to on.
- for the connector (on the front seat airbag assy side) between
the airbag sensor assy center and the front seat
airbag assy (rh), measure the voltage between sfr+
and body ground.
Ok: voltage: below 1 v
2 Check air bag sensor assy center
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 connector to the airbag sensor assy center.
- using a service wire, connect sfr+ and sfr– of the connector (on the front front seat airbag assy side) between the airbag sensor assy center and the front seat airbag assy (rh).
- 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 b0113/42 is not output.
Hint
: codes other than code b0113/42 may be output at this time, but they are not relevant to this check.

- turn the ignition switch to on, and wait at least for 20 seconds.
- check the dtc .
Ok: dtc b0113/42 is not output.
Hint
: codes other than code b0113/42 may be output at this time, but they are not relevant to this check.
4 Use simulation method to check
Replace all srs components including the wire harness
Circuit description
The side squib (rh) circuit consists of the airbag sensor assy center and
front seat airbag assy (rh).
It causes the srs to deploy when the srs deployment conditions are satisfied.

Replacement
1. Replace transmitter battery
Notice:
special caution should be taken for handling each component as they are
precision electronic components.
Using a screwdriver, pry out the transmitter case.
Notice:
do not forcibly pry out the case.
Hint:
tape the screwdriver tip ...
System description
The ecm uses the signals from the throttle position sensor, air–flow meter
and crankshaft position sensor
to monitor the engagement condition of the lock–up clutch.
Then the ecm compares the engagement condition of the lock–up clutch with the
lock–up schedule in the
ecm memory to detect mec ...
Inspection procedure
Hint:
hand–held tester only:
narrowing down the trouble area is possible by performing ”a/f control” active
test (heated oxygen
sensor or other trouble areas can be distinguished). Perform active test using
hand–held tester (a/f
control).
Perform active test using the hand–held tester (a ...
