I installed a new ABS module during the summer and solved my C1214 code
problem. Recently it began a series of codes about every third or fourth
start. The codes this go around are 1689, 1241, 1248, 1265, 1266, 1267,
1268, 1276. I have the description for all of them but was wondering if
anyone knows if this points to a common ground point or another area I
should look for. I can clear the codes while driving and they generally
don't reappear until a follow-up start. The car is a 2001 C5. Thanks. Chris
Without a manual you are spinning your wheels. There are 13 ground
points, 3 on the engine, 1 each on the frame rails under the
headlights, 4 on the doors, (1 each front and rear of the door, some
inside the cabin), 1 up behind each of the 4 wheels. Those are general
locations and may require you to remove items to access them.
From what your are describing I doubt it is a ground and is maybe the
ABS unit. It is ether faulty or the connections were damaged when it
was installed, but who knows when you have no manual to trouble shoot
it properly. Without one it is like trying to hit a curve ball while
standing on third base rather than home plate.
Try this guy if all else fails, some of the ABS units had problems
that may need updated. www.ABSFixer.com His ABS upgrade and guarantee
can make your problems go away as long as you own the car.
issue. I believe I have a wiring or connector problem. it trips 8
codes on start up. Once driving down the road, I can clear the codes and
they go away until the next start. Frustrating at best. I will chase
the grounds on the front end of the car and the big common plug on the
abs module first. I had hoped the codes pointed to a common grounding
I don't have a good service manual. Got a good suggestion?

I second that, forget about after market, auto store manuals, go with
the company prepared manual.
Have you had any battery issues especially a leaker?
