Problem with the M570 engine

[cerokool86]

Good afternoon Engineers, I appreciate the help with other issues. Now I've had the misfortune of having trouble with the 
M570 engine in my Frontier 355. I disassembled the engine compartment and tested it from the maintenance menu, and the engine 
only vibrates; it doesn't turn over. Any help would be greatly appreciated. Thank you and greetings from Mexico.

Just in case can check motor connections ( PDC3 and motor connector ) , or try swap with motor from other position. Usually all good there and PDC20 circuit board is faulty. Need repair, or change it. It is typical problem on LP1500SC ( 350/355 printer ) and LP2000SC ( 370/375 printer ) . Many times had to repair this board. After that motor worked well.

Good afternoon engineer, I already checked with another motor and it's still the same, the error is in 
the circuit board. Could you give me some guidance on where to measure the values with the multimeter?

Nothing to measue here for end users. You need to get working board and change it.

To repair board multimeter is not enough. Need oscilloscope and understanding how board is designed and how to repair it.
