You have a fault in your VSES system, otherwise known as ABS/Traction control. It would store a code. If you press info up, and on/off, it will enter diagnostics. After a segment check it will display ALL? From there the info button up, or down, will scroll modules alphabetically. Locate ABS, then press on/off. It will either display ABS codes, or ABS clear codes. Locate ABS codes, and press on/off. Record the code(s), and report them to me, I will assist you as much as possible.
