as your looking at the diagnostic port plug located below the fuse box facing toward you with the hood open, the top center and the middle second from left terminal need to be shorted together (jumper wire), turn lift ignition on, the engine light will blink, press the gas pedal to the floor 5 times and shut the lift off, remove wire and start lift, code will return if the error is valid.
