CLAAS 75C8h – Claas Tr1 A57 1 Transmission Module: Forward Gear Solenoid Valve Return Current Below Setpoint

The actual current measured on the forward gear solenoid valve return is less than the setpoint value. This may trigger an audio warning and request an

1. 1

   A possible open circuit in the solenoid valve supply harness

2. 2

   A possible short circuit to earth on the solenoid valve

3. 3

   The resistance of the solenoid valve winding

4. 4

   The “Auto 5” module using tool n° 60 05 033 249

1. 1

   Check for a possible open circuit in the solenoid valve supply harness

   Inspect the wiring and connections related to the solenoid valve supply harness for any breaks or disconnections.

2. 2

   Check for a possible short circuit to earth on the solenoid valve

   Inspect the solenoid valve for any signs of shorting to ground, including damaged insulation or foreign material.

3. 3

   Measure the resistance of the solenoid valve winding

   Use a multimeter to measure the resistance of the solenoid valve winding and compare it to the expected value.

4. 4

   Use the “Auto 5” module with tool n° 60 05 033 249

   Access the “Auto 5” module using the specified tool and check or change the configuration if required.
