Lincoln Aviator: High Voltage Battery, Mounting and Cables / General Procedures - High Voltage System De-energizing
Depower
WARNING:
To prevent the risk of high-voltage shock, always follow
precisely all warnings and service instructions, including instructions
to depower the system. The high-voltage system utilizes approximately
450 volts DC, provided through high-voltage cables to its components and
modules. The high-voltage cables and wiring are identified by orange
harness tape or orange wire covering. All high-voltage components are
marked with high-voltage warning labels with a high-voltage symbol.
Failure to follow these instructions may result in serious personal
injury or death.
-
WARNING:
Before beginning any service procedure in this
manual, refer to health and safety warnings in section 100-00 General
Information. Failure to follow this instruction may result in serious
personal injury.
Refer to: High Voltage System Health and Safety Precautions - Overview (100-00 General Information, Description and Operation).
-
Using the FDRS CARRY OUT the Zero Voltage Confirmation routine and follow the on-screen instructions.
-
-
Detach the pin-type retainer and position the electrical connector and wiring harness aside.
-
-
Release the Connector Position Assurance (CPA) clip.
-
-
Depress the tab while pulling the connector until
the hole is completely visible on the top of the connector.
-
-
Insert a suitable tool inside the connector hole to prevent the connector from closing.
-
Using the FDRS COMPLETE the Zero Voltage Confirmation routine and verify the High Voltage System has been de-energized.
Manual Depower

NOTICE:
Manual De-energization should only be performed when a Ford – specific diagnostic tool is not available.
NOTICE:
Excessive use of this method may cause damage to electrical connectors.
NOTICE:
To prevent the risk of high voltage shock, the high
voltage battery cover must not be removed if any of the following
conditions exist:
-
BECM
DTC P0AA6:00 that has been diagnosed to be an internal fault with the high voltage Battery.
-
BECM Diagnostic Trouble Codes (DTCs) P0AA1:00 AND P0AA4:00 are present.
-
BECM Diagnostic Trouble Codes (DTCs) P0D0F:00 AND P0AA4:00 are present (PHEV only).
-
WARNING:
Before beginning any service procedure in this
manual, refer to health and safety warnings in section 100-00 General
Information. Failure to follow this instruction may result in serious
personal injury.
Refer to: High Voltage System Health and Safety Precautions - Overview (100-00 General Information, Description and Operation).
-
Disconnect the Electric Vehicle Supply Equipment (EVSE) from the vehicle charge port. (PHEV only).
-
Turn the ignition ON without depressing the brake pedal (Accessory mode).
-
NOTE:
A scan tool that is capable of performing a self-test on the BECM is required.
-
Using a scan tool perform BECM self test and record the Diagnostic Trouble Codes (DTCs).
-
If BECM Diagnostic Trouble Codes (DTCs) P0AA1:00 AND P0AA4:00 are present.
Refer to: High Voltage Battery, Mounting and Cables - Plug-In Hybrid Electric Vehicle (PHEV) (414-03A High Voltage Battery, Mounting and Cables, Diagnosis and Testing).
-
If BECM Diagnostic Trouble Codes (DTCs) P0D0F:00 AND P0AA4:00 are present (PHEV only).
Refer to: High Voltage Battery, Mounting and Cables - Plug-In Hybrid Electric Vehicle (PHEV) (414-03A High Voltage Battery, Mounting and Cables, Diagnosis and Testing).
-
Turn the ignition OFF.
-
-
Detach the pin-type retainer and position the electrical connector and wiring harness aside.
-
-
Release the Connector Position Assurance (CPA) clip.
-
-
Depress the tab while pulling the connector
until the hole is completely visible on the top of the connector.
-
-
Insert a suitable tool inside the connector hole to prevent the connector from closing.
-
Disconnect the low voltage electrical connector at the High Voltage Battery.
-
Disconnect the high voltage electrical connector at the High Voltage Battery.
-
Wait a minimum of 5 minutes.
