If you were just charging your Mach-E and got these error messages:
Powertrain / High Voltage Reset:
Perform steps exactly in this order.
Second Charging Attempt:
Explanation: Certain charging stations or EVSEs can produce errors that cause the Mach-E to enter a "HV battery disabled" state. This state can only be cleared if the vehicle is unplugged and completely powered down for at least 5 minutes. These errors may be caused by a faulty EVSE, incompatible DC charging station, an incomplete plug connection, or failed HV components on the Mach-E. Fiddling with the gear shift knob without pressing the brake pedal can also cause a powertrain fault if you have outdated gear shifter software.
The fault could be with a particular EVSE, it may have a communication issue that requires a firmware update or replacement to solve. An OBCC module update may be required from your dealer to solve DC charging station compatibility issues.
- Powertrain Malfunction / Reduced Power
- High-Voltage Battery Warning
- Service vehicle soon
- Stop safely now
- Charge fault
Powertrain / High Voltage Reset:
Perform steps exactly in this order.
- Unplug the charger from the vehicle.
- Turn OFF the vehicle completely.
- Open and close the driver's door.
- All screens should go black.
- Do not open or close any doors during the waiting period. You may sit inside the car if you don't touch anything.
- WAIT A MINIMUM OF 5 MINUTES with the car unplugged and completely off (10 min recommended).
- Press the brake and start the car. Observe if any error messages are still present in the instrument cluster after restarting.
Second Charging Attempt:
- Start the car and verify no error messages are shown on the display (see above for reset).
- Authorize the charger if necessary (DC or public charging).
- Insert the charger plug FULLY until it CLICKS with a firm push.
- Immediately observe the charging indicator ring lights and verify they light up BLUE and begin pulsing.
- If the indicator lights do not light up blue or turn RED, there is still a problem with the charging station or your car.
- Move the car to a different charger, perform the above powertrain reset procedure again, and try charging again.
