Thanks for your cooperation
I don't have any tool to detect the malfunction and the screen shows it now Malfunction 039 plus red light and the sound of the alarm
In the beginning, the fault was 014 and the whole hydraulic movement was working only without the engine responsible for the movement of the forward and backward.
My electricity engineer Instead of the back plates, MB 1514 did not change the failure and returned the plates to the correct place appeared error 039 Instead of the rear panels, MB 1514 did not change the failure and returned the plates to their proper place appeared error 039 and stopped working hydraulics also
