Refer to Wiring Diagram Set 12 (Fusion/Milan/MKZ, Fusion Hybrid/Milan Hybrid), Charging System for schematic and connector information. See:
Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The DC to DC Converter Control Module (DC/DC) monitors the PCM relay control circuit voltage. If the PCM relay control circuit to the DC/DC
becomes open or voltage is low, DTC P0A12:16 sets and the DC/DC maintains standard operation of the charging system, though a delay in vehicle
start-up time may occur.
-
DTC P1A12:16 (DC/DC Converter Enable Circuit Low: Circuit Voltage Below Threshold) - Sets when the PCM relay control circuit provides
less than 7 volts to DC/DC C1457D-7.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
