What's wrong?
The G9 control circuit board in this 2017 Tourig Mercedes-Benz Sprinter motorhome is part of the Multiplex G9 system. It acts like a central switch panel for equipment and accessories in the motorhome, sending control signals so those items turn on and off as intended.
The defect is in the control board's protection against excessive voltage. When too much voltage reaches the board, electrical components on the board become damaged and the Multiplex G9 unit fails. The remedy component adds an extra circuit module, which points to the original setup lacking the protection needed for that voltage condition.
There is no warning sign before failure. An owner would not have a specific sound, light, or behavior listed in the recall filing to watch for before the board stops controlling the connected equipment.
Who's affected?
Both listed components trace to the same G9 Control Circuit Board.
