E825, no reverse

Hello all, new to this NEV thing. I recently bought a 2002 E825, put some new batteries in it, runs great in forward but I get nothing but code 006 when I put it in reverse and press the pedal. Anyone see this before, the code in my service manual doesn’t seem to coincide with the issue I am having.

Do you mean -06 ?

If yes, then you are not getting B+ to pin 5 of controller from reverse switch.
Wire fell off switch?
