This is what happens if you don’t use the old U38. You just need to go to drive and do a ReInit, then build your floor table. I can’t say why you have to, but the BatRams don’t last forever. Probably a good time to replace it. What was the original problem with the CPU?

Oh, and if the ReInit doesn’t work, and it will tell you if it doesn’t, you will have to do an Init. But this will put your drive back to defaults. Usually not a problem, especially if it was a new install. But I have had trouble on certain MOD jobs that would not run with default parameters. Had to go through the setup manual page for page to get a running car. Ideally the drive parameters are recorded on site.
