Toyota Corolla Repair Manual: Inspection procedure
1 Inspect fuse(ecu–ig fuse)
- Remove ecu–ig fuse from the instrument panel j/b.
- check continuity of ecu–ig fuse.
Ok: continuity
2 Inspect battery
Ok: voltage: 10 – 14 v
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 (1, 23) of skid control ecu harness side connector and body ground.
Ok: resistance: 1 Ω or less
Check and replace brake actuator assy

Inspection procedure
Hint:
read freeze frame data using the hand-held tester or the obd ii scan tool.
Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, it is
useful for determining whether
the vehicle was running or stopped, the engine was warmed up or not, the ...
