CHEVROLET S-10 ABS PROBLEM

2001 Chevrolet S-10 • 108,000 miles

My power brake vacuum pump won't shut off. Even if I shut pickup off. Is the power source to pump constant hot? Trying to figure out if I have a short or pump has a stuck switch.

It may be the relay for the hydravac pump.

Ok, not a hydrovac. It is an electric pump for the abs. The unit is most likely the issue. Have someone look in the system with a scanner to see if it is commanded on
