Tractor Jerks / eHydro Fault Indicator Flashes

Diagnosis & fix steps

LOGIC: Forward and Reverse Pedal Position Sensors Conflict. ACTION: Calibrate TwinTouch pedals through instrument panel service diagnostics. Inspect dual Hall-effect potentiometers under the right floorboard for physical damage, packed ice, or bent pivot arms.

Red Seal field insights

Mechanical Zero-Stop: Operators stomp pedals aggressively; bent mechanical pedal stops allow the return spring to sit outside the calibrated 0.5V idle window, confusing the drive controller.
