We have 2022 C6000 combi. There rear wheel will not change into forward or reverse mode. Will change into sideways mode. I have checked all the proxy sensors and changed them, they are all working and lighting up. Stopper is set correctly. No damaged wires. PLC board shows forward and reverse solenoid problem. Changed both still wont go into forward or reverse. Front wheels change in all directions properly. Alternator is at 14.6 while loaded and battery is 14.1 loaded
