Toyota Corolla (E120): Diagnostic trouble code chart
Notice
: when removing the part, turn the ignition switch to off.
Hint
: using sst 09843–18040, it connect the terminal tc and cg of dlc3.
If any abnormality is not found when inspecting parts, inspect the ecu and ground points for poor contact.
If a malfunction code is displayed during the dtc check, check the circuit listed that code. For details of each code, turn to the page referred to under the ”” for respective ”dtc no.” In the dtc chart.
When 2 or more dtc’s are recorded, and the problem is not identified, perform circuit inspection of the other dtc’s.

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 ...
Circuit description
A thermistor is built in the engine coolant temperature sensor and changes
the resistance value according
to the engine coolant temperature.
The structure of the sensor and connection to the ecm is the same as those of
the intake air temperature
sensor.
Hint:
if the ecm detects the dtc ...
Inspection procedure
1 Reconfirm dtc
Check the dtc
2 Inspect skid control ecu connector securely connected
3 Inspect skid control ecu connector(ig1 terminal voltage)
In case of using hand–held tester:
check the voltage condition output from the ecu displayed on the
hand–held tester.
