Toyota Corolla (E120): Inspection procedure

1 Inspect fuse(ecu–ig fuse)

  1. Remove ecu–ig fuse from the instrument panel j/b.
  2.  check continuity of ecu–ig fuse.

    Ok: continuity

2 Inspect battery

2 Inspect battery

Ok: voltage: 10 – 14 v

3 Inspect skid control ecu connector(ig1 terminal voltage)

3 Inspect skid control ecu connector(ig1 terminal voltage)

In case of using hand–held tester:

  1.  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:

In case of not using hand–held tester:

  1.  disconnect the skid control ecu connector.
  2.  turn the ignition switch to on.
  3.  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)

4 Inspect skid control ecu connector(gnd terminal continuity)

Measure resistance between terminal gnd (1, 23) of skid

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
