Code 319. Unit intermittently codes 745 as well. - Technical Troubleshooting discussion in Forkliftaction's forums

Crown RC5500:
Code 319. Unit intermittently codes 745 as well.

I have a unit here that is coding 319 at startup. Parts swapping ensued, best I can do is not have it code immediately, but intermittently get stuck needing left and right pedal cycle, immediately code 745, or have no code, but upon acceleration, will feel the shift to the right side and struggle to move until a turn to the right moves it normally. Swapped handle, tiller box, acc3, acc2, acc7, acc1, brake switch, whole harness from a working unit. Software update. Verified acc3 cables and drive motor cables are right. Distribution board with fuses And relays. Brake coils. Help?

Calibrate the brake switch. If that don't work then you need to adjust the brake switch to the brake pot the pot should be at about 20% when the switch is first made up.

745.
Steer pot. It senses movement from the pot4 ( on top of the steer yoke ) without any input from the steer encoder ECR3.( steer encoder is the on tiller)
You can try to calibrate the steering note when it says turn all the way to clockwise it's talking about the actual tire direction not the tiller.
