Need Some Help With Codes
While driving my car on saturday my car decided to tell me reduced engine power, service vehicle soon, service traction control, service abs, and charge system fault. I pulled off the road reset everything and started the car back up only for the charges system fault to come up. I hit reset and it went away however it pops up every time I start the car, the service traction control/abs/vehicle soon keep popping up as well. The reduced engine power comes on at random times. I can start the car 10 times and it will come up 4 of the times. Where do I start to fox these problems? They are driving me crazy!

What's the condition of your battery. Sometimes these random faults can be battery related. A couple of those codes are battery related which backs that idea up. Are they all "C" codes?
The other thing to check is the rubber accordian in the door hinge area. As the final 2 codes are Door Control Module related it could be the issue. The connector can come loose or the wires can chafe and cause a short. Pull back the gaiter and inspect for any damage and then clean and reseat the connector.
If the accordian is OK and the battery is due a change I'd start with that on spec and see if fixes it.

I agree with the battery theory. I've seen this posted within the past month and, if i recall, turned out to be the culprit. Try a search and see what you get until some more theories come in. Best of luck
