Toyota Corolla Repair Manual: 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.
Check and replace brake actuator assy

Circuit description
When the idle switch is turned on, a signal is sent to the cruise control ecu
assy. The cruise control ecu
assy uses this signal to correct the discrepancy between the throttle valve
position and the actuator position
sensor values to enable accurate cruise control at the set speed. If the idl ...
