Check fuse F2 on Transformer.
Procedure
Disconnect the motor plug M15. Run the SDS again. Fault code CF-002 (Open circuit) is displayed?
Y
N
Disconnect plug H.P2 from PCB "H". Check wires for Short circuit across leads, the orange wire M15 to H.P2-10
(violet) and the violet wire M15 to H.P2-3 (orange). Is there Short circuit?
Y
N
