Decipher Nikon Service Diagnostic - Help

Also known as the aperture control assembly, it's the mechanical module which makes up the right side of the mirror box.  They will not perform disassembly/reassembly of this module, to replace the lever itself, as it's complex and probably beyond technician training.  The module is only worth around $120, so the rest of the repair cost is labor.
