1 Reconfirm dtc

  1. Check the dtc

2 Inspect skid control ecu connector securely connected

2 Inspect skid control ecu connector securely connected

3 Inspect skid control ecu connector(ig1 terminal voltage)

3 Inspect skid control ecu connector(ig1 terminal voltage)

In case of using handheld tester:

  1.  check the voltage condition output from the ecu displayed on the handheld tester.

    Ok: normal is displayed.

In case of not using handheld tester:

In case of not using handheld 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)

  1. Measure resistance between terminal gnd (s12, 24) of skid control ecu harness side connector and body ground.

    Resistance: 1 Ω or less

Check and repair harness and connector
