Re: ABS Pump Running Intermittently with key off
Unfortunately there are no relays involved in powering the ABS unit. The main power to feed the unit is on a line from the battery and alternator. This is constant power. The unit should not "wake up" until switched power is applied so either you have a problem with your switched power circuits or a problem with the ABS unit.
If you are up for some troubleshooting and have a meter you can pull the big connector on top of the ABS unit and find both pin 5, with a Gray/Black wire, and pin 3, with a green wire. These are the two switched power leads at the unit. There should be no voltage here with the key off and voltage should be there only in the on position. It is a starting point.
