in CN6).
Release the fuse to check it out with
the system turned off.
Change fuse.
Power board
damaged.
Check voltage in the CN6
connector (pins 1 and 3).

DL1 is on.
Check connector wiring,
position. Change board.
Power supply wire to
the tank damaged.
Check voltage in the CN6
connector (pins 1 and
3) and in the manifold
terminal strip.

connector, but not in the terminal
strip, the wire is damaged.
Check connections
between the connector
and the terminal strip.
Change wire.
