CLAAS 75C2h: TR1 (A57-1) Supply voltage measured on the forward gear solenoid valve when the driver is not controlled (setpoint PWM = 0)

The system detects supply voltage on the forward gear solenoid valve when the driver is not controlling it, indicating a potential issue with the control signal or the valve itself. An audio warning is triggered, and an

1. 1

   The forward gear solenoid valve for proper operation

2. 2

   The wiring and connections to the forward gear solenoid valve

3. 3

   The control signal from the driver to the forward gear solenoid valve

1. 1

   Inspect the forward gear solenoid valve for signs of damage or malfunction

   Check for physical damage, wear, or obstruction that may prevent proper operation.

2. 2

   Check the wiring and connections to the forward gear solenoid valve

   Ensure all connections are secure, free from corrosion, and properly insulated.

3. 3

   Verify the control signal from the driver to the forward gear solenoid valve

   Use a diagnostic tool to confirm that the control signal is being sent correctly when the driver is not active.
