Ford 2021-2022 Owner's manual

  • Hello! I have reviewed the Ford Mustang Mach-E Rescue Cards, which provide key safety information for first responders and service personnel. The document details how to identify high-voltage components, de-energize the electrical system in case of emergency, and disconnect the high-voltage system safely. I am ready to answer your questions about these vehicles and the procedures outlined in this document.
  • How to de-energize high-voltage system?
    Where is the high-voltage disconnect plug located?
    What to do after high-voltage system is depowered?
    How the high-voltage cables are identified?

ELECTRIC VEHICLE IDENTIFICATION
Identication using vehicle characteristics
1. HIGH-VOLTAGE charge port
2. Mach-E badge
HIGHVOLTAGE SYSTEM DEENERGIZING
ALWAYS ASSUME THE VEHICLE’S HIGH-VOLTAGE SYSTEM IS POWERED UP!
BEFORE ACCESSING THE VEHICLE MAKE SURE THAT ANY EXTERNAL POWER
SUPPLY IS DISCONNECTED (e.g. electric charger, electric tools). Failure to follow
these instructions may result in serious personal injury or death.
HIGHVOLTAGE ELECTRICAL DISCONNECT FEATURES
WARNINGS:
Removing the service disconnect will disconnect the high-voltage from the
vehicle. The high-voltage battery pack will remain live and dangerous. Do not cut the
high-voltage battery case. Do not penetrate the high-voltage batteries or case in any
way. If possible, isolate and avoid contact with high-voltage vehicle components.

To prevent the risk of high-voltage shock, always follow all warnings and service
instructions precisely including instructions to depower the system. The high-voltage
system utilises voltage in excess of 450 V DC. This voltage is provided through high-
voltage cables to components and modules. The high-voltage cables and wiring
are identied 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.
Ignition is in the OFF Position - Any time the ignition is in the OFF position (and the
vehicle is not being charged), the high-voltage system is deactivated.
Service Disconnect - Whenever the service disconnect is removed, the high-voltage
system is disabled.
HIGHVOLTAGE SYSTEM DEENERGIZING  METHOD 1
1. Ensure the vehicle transmission gear selector is in the PARK position. Check that
the vehicle READY light is o to verify the high-voltage system is disconnected.
2. If the vehicle READY light is on, press the engine start/stop button to turn o the
ignition.

HIGHVOLTAGE SYSTEM DEENERGIZING  METHOD 2
The high voltage battery system uses a low voltage disconnect plug that opens the 12-
volt contactor control supply circuit and is located in the engine compartment. When
the service disconnect plug is disconnected the high voltage contactors that supply
high voltage to the vehicle are unable to close.
1. Open the hood.
2. Remove the driver side beauty cover.
3. Release the Connector Position Assurance (CPA) clip.

4. Depress the release tab and slide out until the OFF label is visible.
5. Insert a suitable tool in the lock out to prevent reinsertion.
The high-voltage system may retain a dangerous level of voltage for a short
time after the high-voltage system is depowered. Wait 5 minutes for the voltage to
dissipate before beginning service. Failure to follow this instruction may result in
serious personal injury or death.
