What's wrong?
The G9 electronic control module in the 2019-2020 Prevost H3 and X3 coaches is part of the coach electrical system. It is an electronic control center circuit board that helps control equipment and accessories in the motorhome. When the electrical system stays within its intended range, the module sends and manages those control signals normally.
The problem starts when the G9 sees voltage greater than 18 volts. That excess voltage damages components on the circuit board, and the module can fail. Firefly and Spyder inspected a coach with a G9 module after a thermal event, then identified a protection board as the fix. The remedy part is a visible red component with an LED, which helps distinguish it from the original setup.
There is no warning sign before failure. An owner should not expect a warning light, message, sound, or change in operation before the board is damaged.
