Fendt 0B.1.B2 – A050 - ECU, basic control unit: A050 - ECU, basic control unit TEACH-IN

EEPROM checksum error, initialising sequence data storage. The memory storage for the tractor's TEACH-IN (headland management system) sequence data has become corrupted or failed a checksum validation during initialization.

1. 1

   Verify the fault code using the tractor's terminal or diagnostic tool. Note that fault codes stored in the A050 basic control unit can only be deleted using the appropriate FENDIAS diagnostic software.

2. 2

   Check if the TEACH-IN functions are operable. The primary consequence of this fault is that the sequence data is corrupted and the TEACH-IN system will not function properly.

3. 3

   Attempt a software reset before condemning the module, as EEPROM checksum errors can sometimes be resolved by wiping and rewriting the memory block.

1. 1

   Connect diagnostic software

   Connect the tractor to the FENDIAS diagnostic software.

2. 2

   Access module

   Access the A050 Basic Control Unit module.

3. 3

   Delete sequence data

   Delete the existing TEACH-IN sequence data from the memory.

4. 4

   Perform EOL programming

   Perform EOL (End of Line) programming to re-initialize the sequence data storage and reprogram the module.

5. 5

   Test functionality

   Test the TEACH-IN functionality. If the EEPROM checksum error immediately returns or the module refuses to accept EOL programming, the internal memory of the A050 ECU is physically defective.

6. 6

   Repair or replace ECU

   If defective, remove the A050 Basic Control Unit and either send it out for specialized electronic repair or replace it with a new/remanufactured unit.

7. 7

   Program replacement unit

   If a replacement unit is installed, you must perform EOL programming on the new module to configure it to the tractor.
