Toyota Corolla (E120): 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.
Ok: ”normal” is displayed.

In case of not using hand–held tester:
- disconnect the skid control ecu connector.
- turn the ignition switch to on.
- measure voltage between terminals ig1 (3) and gnd (1,
23) of skid control ecu harness side connector.
Ok: oltage: 10 – 14 v


4 Inspect skid control ecu connector(gnd terminal continuity)

- Measure resistance between terminal gnd (s1–2, 24) of
skid control ecu harness side connector and body
ground.
Resistance: 1 Ω or less


Check and repair harness and connector
5 Go to combination meter system(abs warning light)

- Disconnect the skid control ecu connector.
- using service wire, connect terminals wa (30) and gnd (1, 23) of skid control ecu harness side connector.
- turn the ignition switch to on.
Ok: abs warning light goes off.
