Good afternoon, I am working on a Hyster R30XMS3 that has a status code Steering Encoder. The lift will come on, no forward/reverse, but the lift will raise and lower. I have checked the CANbus system to ensure its ability to communicate. I have checked the wiring to the encoder and it appears to be in good shape. I have my positive and negeative to the steering controller. This unit recently had the MDU replaced under warranty by Hyster. I am in the process of trouble shooting the wiring from the master controller and steering pot.....any suggestions as to what I need to be looking for that is a common cause for this issue?
