A. Plunger does not extend out from cup. (Refer to Figure 5.4.)
1. Remove the top of the cup, and check the harness connection at pinout P3 on the cup logic board.
(Refer to
Figure 5.5.)
Make sure there are no loose wires and the connection is tight.
2. Using an ohmmeter, check for continuity on all wires in the harnessing from the DMC to the cup logic board.
If
any
wire fails, replace the harness. If
all
wires pass, replace the cup logic board. If the problem persists,
replace the plunger motor.
