What's wrong?
The G9 Electronic Control Module in 2019-2020 Triple E Rv Wonder motorhomes is part of the Firefly electrical control system. It acts as a control center for coach electrical functions, taking power and switching circuits so the motorhome equipment responds to the controls inside the living area. The module needs stable voltage to keep those circuits opening and closing only when commanded.
The problem starts when the Multiplex G9 electronic control center receives excessive voltage greater than 17 volts. That over-voltage damages components on the module and allows continuous conduction, which means electricity keeps flowing through a circuit instead of stopping when the control is off. The recall remedy adds a highly visible red component with an LED indicator to the original Multiplex G9 ECM.
There is no warning sign before failure. The recall does not identify an early driver-visible symptom before the electronic control module stops working correctly.
