Inspection and Verification
Before
diagnosing or repairing the Direct Current/Alternating Current (DC/AC)
Inverter system refer to the Owner's Literature and
REFER to: Direct Current/Alternating Current (DC/AC) Inverter - System Operation and Component Description (414-05 Voltage Converter/Inverter, Description and Operation).
for proper system operation.
Diagnostic Trouble Code (DTC) Chart
Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).
Diagnostic Trouble Code Chart
Module | DTC | Description | Action |
---|---|---|---|
BCM | B1330:01 | DC/AC Inverter Module: General Electrical Failure | GO to Pinpoint Test A |
BCM | B1330:02 | DC/AC Inverter Module: General Signal Failure | GO to Pinpoint Test C |
BCM | B1330:08 | DC/AC Inverter Module: Bus Signal/Message Failures | GO to Pinpoint Test C |
BCM | B1330:49 | DC/AC Inverter Module: Internal Electronic Failure | GO to Pinpoint Test D |
BCM | B1330:55 | DC/AC Inverter Module: Not Configured | GO to Pinpoint Test D |
BCM | B1330:9A | DC/AC Inverter Module: Component or System Operating Conditions | GO to Pinpoint Test D |
Pinpoint Tests
NOTE: The electrical device that is powered by the AC power point must not exceed 150 watts. If the green LED is flashing, the AC power point may be overloaded, overheated or shorted. Unplug the electrical device from the AC power point and cycle the ignition. Refer to the Owner's Literature to determine if the electrical device is appropriate for the AC power point.Refer to Wiring Diagrams Cell 44 for schematic and connector information. Normal Operation and Fault Conditions The engine must be started for the AC outlet to begin operation. No power will be provided to the AC outlet when the LED is flashing.

Refer to Wiring Diagrams Cell 44 for schematic and connector information. Normal Operation and Fault Conditions The direct current/alternating current (DC/AC) inverter receives a signal from the BCM over the LIN whenever the engine is running. If the direct current/alternating current (DC/AC) inverter does not receive this message for 13 minutes, the inverter stops supplying 110 volts to the AC power outlet and the LED indicator flashes. The system can be reset by cycling the ignition from ON to OFF and back to ON, however the system only operates for another 13 minutes unless the signal is received from the BCM that the engine is running.
