Then the problem is typically in the wheel speed sensor circuits. Most common issue is breakage of the front wheel speed sensor wiring harness. Check the wiring coming off each of the front hubs for breakage. If the wires look intact, pull on the wires, as they may be broken inside the insulation. If the wire stretches and comes apart, you have found your break. These harnesses are available at most parts stores and online through Amazon or Ebay.
