Re: Reboot onboard Computer???
For whatever it's worth I had the EXACT same experience (dash lit up like xmas tree with warning lights, and QL going up and down at every stoplight). They claimed there were no codes for over/under voltage (that would have led me to suspect a grounding issue) but a laundry list of other codes and the solution was to "reboot the computer". They claimed that it was not something that could be done outside the shop. I am making no clams to the validity of that statement but just what I was told. Needless to say that was 2 weeks ago and I have not seen a repeat of the issue.
