High ground impedance of ABS pump motor

The easiest way to do this is to unplug the ABS pump, find out the pump body's hitch wire, and lead a hitch wire directly from the negative terminal of the battery to the negative terminal wire of the ABS pump, and then see if the ABS system is working properly, and if it is normal, then overhaul the hitch wire, and if it's not normal, then it's a problem with the ABS pump itself.
