Toyota Corolla (E120): Inspection procedure
1 Check p/t squib(rh) circuit(airbaga 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).
Hint
: make sure that the connector is not damaged (the lock button is not disengaged, or the claw of the lock is not deformed or damaged). If the damage is found, replace the wire harness.
- release the airbag activation prevention mechanism of the connector (on the airbag sensor assy center side) 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 pr–.
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.
- 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 b0130/63 is not output.
Hint
: codes other than code b0130/63 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 b0130/63 is not output.
Hint
: codes other than code b0130/63 may be output at this time, but they are not relevant to this check.
Use simulation method to check
Other materials:
Evap monitor (vacuum pressure monitor) (continued)
Preconditions
The monitor will not run unless:
mil is off.
Fuel level is approximately 1/2 to 3/4.
Altitude is 7800 feet (2400 m) or less.*
Engine coolant temperature (ect) is between 40°f and 95°f (4.4 °C and 35
°C).
Intake air temperature (iat) is between 40°f and 95 ...
Symptom confirmation and diagnostic trouble code
Hint:
the diagnostic system in corolla has various functions. The first
function is the diagnostic trouble
code (dtc) check, in which a malfunction in the signal circuits to the ecu
is stored in code form in
the ecu memory. Another function is the input signal check, which checks if
...
General information
There are many ecu controlled systems used in the corolla. In general, ecu
controlled system are considered
to be very intricate and require a high level of technical knowledge and expert
skill to troubleshoot.
The fact is, however, that if you proceed by inspecting the circuits one by one, ...
