VSC TRAC, TRAC OFF, ABS lights -No check engine
Hi,
The VSC TRAC, TRAC OFF, ABS lights come one but I get no check engine or codes, truck drive fine. If I reset the ECU they will go off once I hit the brake pedal and you can hear that pump noise from under the hood.-(that noise it makes after starting up).
It does not seem to be mechanical such as a bad ABS wire, low fluid, I cleaned the connections on the master cyl. How do I diagnose this and/or anyone have and experience with this?
Thanks
Doug

Sounds like you have an issue with your master cylinder. You need to get the failure code and only certain shops will be able to pull it for you. The dealer is one of them, but there are other shops where they spend $5,000 on a scan tool that will read everything.
