The anti-lock brake system (ABS) pump may stay running after the ignition is turned off causing the battery to go dead. Our technicians tell us that the ABS control module should be replaced to correct this fault.Google+

I have replaced the module on my trk but the pump motor still stays running unless I pull the fuse to it.
This is something that has bothered for about three or four years and I couldn't find why the battery was going dead after a week of not starting it.It now runs all the time the fuse is in.
I was unable to afford to replace the module, so the fuse was pulled to stop the pump and smiley face stickers were placed over the nice red lights. I have to put the fuse back in whenever it comes up for emissions test as both the brake & abs lights stay lit. The brakes work just fine. No abs though. Can't afford the $1000 to fix it :(

ABS brake light came on today. When I parked my truck, turned it off and got out I noticed a humming sound coming from under the truck directly beneath the drivers seat. Crawled under to check it out and discovered its the ABS pump motor. Had to pull the ABS fuse to make it turn off. Internet says the control module (plugs in at same location as pump) is the problem. Did some checking and the part alone is over $500...OUCH!!

ABS motor ran even with engine off. Pulled the ABS fuse out 33,000 miles ago (just can't afford to replace it).When going for the annual state inspection sticker, have to put the fuse back in to turn off the lit brake light on the instrument cluster in order to pass the inspection. After the inspection, the fuse is taken back out.
