A 2018 CASE 695ST developed SCR/AdBlue faults and entered limp mode. The owner reported that the accelerator pedal stopped responding and the tractor could no longer work with the required power. The video identifies fault codes 3157 and 3158; similar problems had previously been checked by a dealer.

The technician connected diagnostic equipment, read and reset the faults, then removed the EDC17C49 control unit. The software was read and written in Bench mode through the ECU pins without opening the unit. The calibration was changed for the SCR/AdBlue system, and the limp-mode response associated with these faults was disabled.

After the work, the tractor responded to the accelerator again, the faults had been reset and limp mode was no longer active. These are the checks reported immediately after the repair; the video does not document long-term operation.
