R420 TsX AWD slope sensor?

[NinkyNonk]

Hello, does anybody know how the Husqvarna R420 TsX rider lawnmower senses that it’s on slope? Is it part of the ECU? I can not find any other sensor.

With the machine on flat ground, and weight on the seat, the slope indication constantly flashes and the buzzer periodically sounds which results in the PTO disengaging. So frustrating, making the mower almost unusable.

Many thanks

Not familiar with the AWD but it kinda sounds like the weight transfer switch is flaky or the weight transfer system is out of adjustment. Just a shot in the dark here.

The service manual doesn't say how the slope indicator works and don't see anything like a slope sensor listed in the IPL either.
