I have an RD5200SAC here with kind of a strange one. Truck is faulting 216 and drops to limp travel and cuts out accessories. If I cycle power to reset, all functions (including tilt) work perfectly. As soon as you move the MTC to travel fwd or rev it throws the 216 code and limps. And I mean just moving the MTC in the slightest FWD/Rev!

Going through the troubleshooting steps, the solenoid checks out good. I even went as far as swapping the wires with the sideshift solenoid and testing and 216 still came up (if the solenoid was bad I would expect it to have changed to a 215).

When I hook my meter in line with the tilt solenoid. I see about 20 v when tilting back and fwd. Zero volts at rest. When I move the MTC to fwd or rev slightly I'll see a jump to about 18 v then the truck faults and the voltage stays at 18 v until I cycle power again.

The only other thing is Access 3 is flashing the 216 rather than access 2.

Thanks!
