HUC-3 Abs Control Unit Ground Check
Ensure ignition is off. Set ohmmeter to 200-ohm scale. Measure resistance between ABS control unit terminals "L" (Black wire), "N" (Black wire), "P" (Black wire) and ground. Resistance should be less than 5 ohms. If resistance is correct, replace ABS control unit. If resistance is not correct, repair Black wire(s) to ground.
