Error code BCU 523756.16 is triggered when the Basic Control Unit (BCU) of a John Deere vehicle detects that the lowering deadband—the gap between the adjustment cam of the stepper motor and the lower valve of the hitch valve—is too high during the calibration process. This excessive play can result in a delayed or sluggish…
