    No red triangle... But the usual suspects of DTC are back. Looks like i need to address the battery. However, surprisingly nothing appears for Engine...but only as INC. So its not complete? I think i need to check fuses. I already mentioned all fluids are great.

    The test drive was nothing dramatic, but up hill, down hill. Soft acceleration to hard acceleration, same for brakes. Everything seems the same. I saw no reduction in performance...for a 2005.
    The dash monitor is impossible to read, its burnt out...so no arrows.
    I forgot to do the battery monitor test in the dash, i can do that later tonight.
