ABS BRAKE FLUID PUMP

1992 Plymouth Voyager

Brakes problem
1992 Plymouth Voyager 6 cyl Front Wheel Drive Automatic 210000 miles

I have a 1992 Plymouth Grand Voyager with ABS and 3.3L v6 engine. The electric power brake pump activates for a few seconds, then stops, then about 5 seconds later it activates again, and again and never stops cycling. There is no fluid loss and the brakes still work. It acts as if the fluid is passing back through an internal check valve and bleeding off the pressure. Do you suspect the problem is in the pump unit that is mounted on the transmission or the master cylinder unit above? Thanks so much. Any help or references appreciated. Thanks, Gene

First step is scan for codes with a scan tool that reads Chrysler ABS codes, this will pinpoint the bad parts or circuits to check for shorts.
