P0A0A - High voltage interlocking circuit

Post by ZionXIX »

Car was running rough at idle this morning with no CEL. P0A0A showed up on torque app. I assume thats a generic code. Any thought on a high voltage interlocking system for the p80s? Never heard of that part. Could this be an alternator or voltage regulator problem?

Shouldn't be possible as best I can tell. My guess is that Torque had some form of data corruption during it's exchange of data.
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.
