Cadillac STS Forum 2005 through 2012
Today I checked battery after car sat all night. It was 12.1 volts .
Hooked up scanner and started car, went up to 13.4 volts, when I went to pcm it was saying it was getting 13.6, after idling for a few minutes the car died and spit out code p0601.
When I checked battery again it said 11.9...
