1 Reconfirm dtc


2 Inspect skid control ecu connector securely connected


3 Inspect skid control ecu connector(ig1 terminal voltage)




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

- Check the dtc




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



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



- 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.
