Does anyone have experience with the ABS Electro-Hydraulic Control Unit on a 01 Suburban? Mine seems to have gone south. I got a call from my wife that the ABS light was on and there was a loud noise coming from underneath the truck. I went over to her work and the motor to the EHCU was constantly running. The only way I could stop it was to disconnect the power harness. Removing brake system fuses did not help. I carefully drove it home and left her my truck.
The EHCU is on the left frame rail right next to the fuel filter. From the phone calls I made, the dealer is the only one that carries the part - it is about $800.
Does anyone know if the whole unit has to be replaced? Is there some other electronic control that would cause the motor to constanly run?
Thanks.
