oh okay...you have the transmissive reels version.
You also have an LCD in the topbox too right?
I'd play around with the harnesses....might be just a loose reel connection somewhere losing COMM with the computer.
If you go into diagnostics, will anything come up on the reels?
Can you do any tests on them from there?
It won't hurt to do another CLEAR and try to re-install the software.
Check the batteries in the MPU too...even though you didn't get a low battery notification, it's possible maybe one of them dropped below a threshold and is causing problems.
