CLAAS 75D2h – Claas Tr1 A57 1 Transmission Module: Inconsistency Between Crawler Range Engaging Contact and Mechanical Status

There is an inconsistency between the information from the crawler range engaging contact and the mechanical status of the crawler range. This may affect the REH (A58) lifting module and its associated functions. The issue may be related to the theoretical speed sensor, the slow range contact, or the status of the crawler range or range module.

1. 1

   The theoretical speed sensor (B227)

2. 2

   The slow range contact (Z150)

3. 3

   Status of the crawler range

4. 4

   Status of the range module

5. 5

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

1. 1

   Check

   The theoretical speed sensor (B227) for proper function and connection.

2. 2

   Check

   The slow range contact (Z150) for proper function and connection.

3. 3

   Check

   The status of the crawler range and the range module for any signs of malfunction.

4. 4

   Use

   The 'Auto 5' module using tool n° 60 05 033 249 to diagnose and, if required, change the module.
