ground) / Inspection procedure
Toyota Corolla (E120): Inspection procedure
1 Check p/t squib(rh) circuit(airbag sensor assy center – front seat outer belt 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 seat belt pretensioner (rh).
- for the connector (on the seat belt pretensioner side) between
the airbag sensor assy center and the seat belt pretensioner
(rh), measure the resistance between pr+
and body ground.
Ok: resistance: 1 mΩ 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 pr+ and pr– of the connector (on the seat belt pretensioner side) between the airbag sensor assy center and the seat belt pretensioner (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 b0132/61 is not output.
Hint
: codes other than code b0132/61 may be output at this time, but they are not relevant to this check.


3 Check p/t squib (rh)
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 seat belt pretensioner (rh) 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 b0132/61 is not output.
Hint
: codes other than code b0132/61 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 vapor pressure sensor and the vsv for the canister closed valve (ccv) are
used to detect abnormalities
in the evaporative emission control system. The ecm decides whether there is an
abnormality in the evaporative
emission control system based on the vapor pressure sensor signal.
Dtc p0 ...
Changing the engine switch positions
1 “LOCK”
The steering wheel is locked and the key can be removed. (Vehicles with an automatic
transmission or continuously variable transmission: The key can be removed only
when the shift lever is in P.) 2 “ACC”
Some electrical components such as the audio system can be used.
3 “ON ...
Circuit description
The srs warning light is located on the combination meter.
When the srs is normal, the srs warning light lights up for approx. 6 Seconds
after the ignition switch is
turned from the lock position to on position, and then turns off automatically.
If there is a malfunction is the srs, the srs ...
