2003-12 code

Hyster H155FT

So have no forward and reverse. went through the full trouble tree everything in the canbus tests good. pulled the TCM out and nothing on the LCD screen have power at 2 wires going in and 2 grounds. tested the tranzorb and that also tests good. what am i missing here

***update**
So back probed the three power wires 2 are always on an one is key on. with the controller hooked up all of them drop to like 4-5 volts swapped out PDM with known good one and no change. am i starting to look at a VSM here ?? thanks

Thanks

DTC 2003-12 is "CANbus Error With TCU" so if you've verified that the TCU is good, I'd check and make sure your wires aren't damaged and the connectors are good (sometimes the wires break out of the connectors) and check for corrosion.
