The Saab boards aren't being much help with this one so far, so perhaps someone here can better guide me in.
04 Saab 9-3 Aero Convertible, and I do have the Saab WIS software, but no Tech2 scanner.
Car occasionally pops up the check engine light with a P0687 code.
What this code means in the Saab world is confusing, to say the least. It's a voltage problem, but various things say it's high, it's low, it's shorted to ground. Which relay it is and where it is, that's never disclosed. You would think the Saab software would help, it doesn't.
So, do any of you folk happen to know which relay I should be looking for under the hood of a 2004 Saab Aero convertible?
And this great looking thread is just plain wrong. http://www.saabscene.com/forum/threads/160234-DTC-P0686-P0687-P0689-or-P0690-(ENGINE-WILL-NOT-START) There is no KR75 relay in the car, and it appears to actually be a diagnostics for a Vauxhall instead.
