NOTE: Check for shorts to frame. Check for shorts or openings in wiring between the Carriage Manager, Steer/Tractor Manage, and Guidance Manager. Check the power supply voltages on the STM. If they are not steady or dip during operation, test all components and wiring to the components that use 12V or 5V for shorts. Replace the STM.
