Check if the result is normal?
YES>To step 5.
NO>Repair or replace harness.

5. Detect the left front wheel speed sensor on the ground and power short-circuit .

(a). Make sure to turn off the ignition switch.
(b). Disconnect the ESP ECU connector A08 and the left front wheel speed sensor
connector A31.

(c). The resistance between the left front wheel
speed sensor connector A31 and the
OFF A31
ground connection is detected.
