Own 2005 Western Star. Have been to 2 diff. Western Star dealers with no luck and $500 later. Check engine or stop engine light flickers. This prob. is intermittent but seems to happen more when hit bumps. Have had grounds checked, batteries, ECM etc.. also no active or inactive codes. Outside of the flickers truck runs great, no power loss or other issues, any ideas?:sadbanana:
Been to the dealers with no results! Stop engine/check engine light flash!

Has to be a wiring issue if it is just a "flickering" of the light. Could possibly be related to the ignition wiring, though that is just a guess. One of those things that will be a nightmare to find.
Since it is not causing any problems, other than an annoyance, I would tinker around with it during when you have the time, but wouldn't get too concerned with it. Basically just follow all of your wiring harnesses and look for anything that might be loose.

All the wires under the dash been checked? Sounds like a loose ground wire..or the bulb in it's socket might be looses.
this IS a ground wire problem. the relay/fuse panel can be loose at its mount to the dash. the inside of this panel can have a loose ground wire. the flickering indicates a wire arcing at ground..............
how do i KNOW THIS..........??
my Mack did the same thing.....
mack, pete, kwhopper, ford, sterling, whatever...............
the dash panel fuse/relay panel loosens up.............OR the ground connection behind it does...........
What engine? Most electronic engines drive the check/stop engine lamps from the ECM itself, I know that you can monitor lamp output from module in most diagnostic software. If problem is easily repeatable, might could get shop to hook up the computer and watch the outputs for changes, that way you could narrow it down between an electronics problem and an electrical problem. Also, Western Stars have a module behind inst. panel that controls telltale lights if i remember correctly. You could have an issue there also.

A piece of black tape over the light. (just kidding!) Like the others have said, it is most likely a ground issue or a loose connection somewhere. If you paid a shop to fix it, and they said it was fixed and it is still a problem, go back to that shop and make them fix it right or give you your money back.
It's all good, sometimes bumping a thread wakes up sleepers! Thanks for your contributions here.
