CLAAS 7624h – Claas Tr2 A57 2 Transmission Module: High-Pressure Brake Pressure Too Low

The high-pressure brake pressure is below the expected range during initialization. The sensor reading is significantly higher than the actual pressure in the circuit. This may affect the proper operation of the braking system.

1. 1

   The hydraulic circuit (valve, pipes, switch…)

2. 2

   Braking pressure sensor (B233)

3. 3

   High pressure braking solenoid valve (Y329)

4. 4

   Voltage delivered by the transformer (V24)

1. 1

   Check the hydraulic circuit

   Inspect the valve, pipes, and switch for any damage, blockage, or leaks.

2. 2

   Test the braking pressure sensor

   Verify the functionality of the braking pressure sensor (B233) and ensure it is providing accurate readings.

3. 3

   Inspect the high pressure braking solenoid valve

   Check the high pressure braking solenoid valve (Y329) for proper operation and connection.

4. 4

   Verify the voltage delivered by the transformer

   Measure the voltage delivered by the transformer (V24) to ensure it is within the correct range.

5. 5

   Use the specified tool for the Auto 5 module

   Use tool number 60 05 033 249 to check the “Auto 5” module and replace it if necessary.
