CROWN RR52855S-45 Monitor Disabled/Check Load Fault

Lift has a fault that shows "Monitor disabled" when forks are fully tilted down. Shows "Check Load" when fully tilted up. There is no fault shown when the forks are not at the end of travel. When I go into the Calibration Menu to C7 to calibrate the TPA "tilt position assist" feature it doesn't show C7 option. It goes from C6 to C8 even though it have the tilting forks installed... Any help or insight would be appreciated!

The Tilt Position Assist switch itself might be defective, the 18/3 Mast Cable that is strictly dedicated to the Tilt Position Assist switch might have an open wire, which means you'll need to replace that 18/3 cable.

Might check for a broken spring in the FKS switch. Its on the left ide of the fork carriage. It could also be in Access 1, power for the circuit is generated there.
