    Hi Akshay,
    The error code you send refers to missing of 48V DC- So I would recomend to check first fuses F9 and F10 on the GKM electronic board , later on check if you have on the X5 connector 48V output voltage.

    Do what beguin said, you have to do an inspection for this kind of problem. Usually failures like this are caused by switches
