I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt
move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com

I had a skim module go out in mine in the ignition, and I have a 2001. It's a 100 part, and now it starts fine.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

I might have a solution to this problem......if you open up your dash where all your gauges are, check to see how the wire harness connections are. If one of the clips on the wire harness is broken, you will not get a proper reading. I had this problem with my oil gauge. I had to change my dash lights at one point, and when i tried to undo all my harness clips i accidentally broke one of my clips for the oil gauge. Right after i put it all back together, my oil gauge went haywire. It could be as simple as replacing a simple harness clip. Its worth a shot:)
