What's wrong?
The master leveling controller on 2022-2023 Terex Tm-Series aerial devices is the electronic controller that keeps the work platform level as the boom moves. It reads the platform position and commands the leveling system so the platform stays upright for the operator and tools. The upper control enable trigger allows boom functions to run while the operator holds it.
On affected machines, the tilt-control software can lose its ability to keep the platform level when power to the master leveling controller is cut while the enable trigger is being squeezed. Terex traced field reports to disconnected or severed controller power wiring, including damage to a cover that contacted another object. With the controller power interrupted at that moment, the platform can dump instead of holding its level position.
The warning sign is tied to the failure itself. When power is lost to the platform tilt controller, the platform can stop maintaining a level position while the upper control enable trigger is squeezed.
Who's affected?
Spans the 2022 and 2023 Tm-Series with the same master leveling controller, which ties the platform-leveling controls and software to the repair path.
