Ok: operation sound of abs motor is heard.



  1. Reconfirm dtc

  1. Clear the dtc (see page bc-47).
  2. Start the engine.
  3. Drive the vehicle at a speed of 6 km/h (4 mph) or more for several seconds.
  4. Check if the same dtc is output (see page bc-47).

Result




Replace abs and traction actuator assembly

  1. Inspect fuse (abs1)

  1. Remove the abs1 h-fuse from the engine room no. 1 Relay block.
  2. Measure the resistance of the fuse.

Standard resistance: below 1




  1. Check wire harness (skid control ecu - battery and body ground)
