  1. Check the operation sound of the abs motor individually when operaing it with the hand–held tester.

    Ok: the operation sound of the abs motor should be heard.

2 Inspect skid control ecu connector(+bm terminal voltage)
2 Inspect skid control ecu connector(+bm terminal voltage)
Toyota Corolla. Inspect skid control ecu connector
  1. Disconnect the skid control ecu connector.
  2. measure the voltage between terminals +bm (24) and gnd (1, 23) of skid control ecu harness side connector.

    Voltage: 10 – 14 v

    3 Inspect fuse(abs no.2 Fuse)
3 Inspect fuse(abs no.2 Fuse)
Toyota Corolla. Inspect fuse
  1. Remove abs no.2 Fuse from the engine room r/b.
  2. check continuity of abs no.2 Fuse.

    Ok: continuity

    4 Inspect skid control ecu connector(gnd terminal continuity)
4 Inspect skid control ecu connector(gnd terminal continuity)
Toyota Corolla. Inspect skid control ecu connector
  1. Measure resistance between terminal gnd (1,23) of skid control ecu harness side connector and body ground.

    Resistance: 1 Ω or less
