Hi there. I am Cam. This is a VERY big pain in the backside. The reset is very specific to the message displayed. So what you need to do is see the document attached. Follow through the 2011 chart and follow EXACTLY what it says. Before starting, go in and delete the RVP reduced vehicle power or speed history before going any further.
