CLAAS 75CBh – Claas Tr1 A57 1 Transmission Module: Insufficient Current to Reverse Gear Solenoid Valve

The current sent to the reverse gear solenoid valve is insufficient, indicating a current regulation problem. This may be caused by issues with the power supply or the solenoid valve winding itself.

1. 1

   The battery voltage

2. 2

   For a possible resistance on the solenoid valve supply

3. 3

   The solenoid valve winding

1. 1

   Check the battery voltage

   Verify that the battery voltage is within the specified range for the system.

2. 2

   Inspect the solenoid valve supply for resistance

   Check for any resistance or poor connections in the circuit supplying power to the solenoid valve.

3. 3

   Test the solenoid valve winding

   Measure the resistance of the solenoid valve winding to ensure it is within acceptable limits.
