Wiring diagram

Refer to dtc c0273/13, c0274/14, c1361/91 (see page bc-79).

Inspection procedure

  1. Perform active test by intelligent tester (motor relay)

  1. Select the active test, generate a control command, and then check that the abs motor relay operates.

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)

Check for intermittent problems
Hint: Inspect the vehicle's ecm using check mode. Intermittent problems are easier to detect with the intelligent tester when the ecm is in check mode. In check mode, the ecm uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detec ...
