Hi, I'm stuck with this issue. Customer have a Cat ET4000-AC, ETB1451649. I had to replace speed controller card and the right MicroCommand card. After installing both card, on the dash board, it's appearing this APP-A, and nothing works. Is anybody have an idea what is that?

Thanks for your answer. I did found the problem. There's a little 3 position metal toggle switch just under the battery connector underneath the floor. It have to be placed in the central position, it wasn't, it was placed in the programming mode.
I had also faced the same kind of speed controller issue in my caterpillar 2EC25 Forklifts models. I fix this issue individually, I have a self-guided service manual of this model. This service manual helps a lot to fix the issue. You can just also try the service manual to fix all kinds of issues, just visit reliable-store dot com for all models service manual.
