charging TESLA MODEL Y 2023 Service Manual

UMC_a005
Unable to charge with Mobile Connector
Voltage too low / Try a different wall outlet
What this alert means:
The vehicle cannot charge, or charging is interrupted, because either the Mobile Connector:

This does not indicate an issue with your Mobile Connector or vehicle, but instead points to an issue with the wall
outlet / electrical installation the Mobile Connector is connected to.
A warm outlet may be caused by a plug that is not fully inserted, a loose building wiring connection to the outlet, or
an outlet that is beginning to wear out.
What to do:
Make sure your adapter is fully plugged into the outlet. If charging speed does not return to normal, contact an
electrician to inspect the outlet and building wiring connections to the outlet and complete any repairs needed.
If the outlet is worn, it should be replaced with a high-quality outlet. Consider upgrading to a Tesla Wall Connector
for greater convenience and highest charging speed.
UMC_a009
Cannot charge - Charge handle temperature high
Check charge handle or charge port for debris
What this alert means:
Charging has been interrupted because the Mobile Connector has detected a high temperature in the charge handle
that connects to your vehicle

After unplugging from the power source (wall outlet), inspect the wall plug adapter connection and the Mobile
Connector control box connection for any obstructions or moisture. Make sure any obstruction has been removed
and any moisture has been allowed to dry, then try re-inserting the wall plug adapter into the Mobile Connector and
then connecting to the power source (wall outlet).
Once the Mobile Connector control box temperature has decreased and any obstruction has been removed, the alert
should clear and charging should possible.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle

First, confirm the lack of effective communication is caused by the Mobile Connector rather than an issue with your
vehicle. This is usually the case.
To confirm this, try charging the vehicle using different external charging equipment.

UMC_a014
Wall plug adapter error - Charge rate reduced
Plug adapter fully into Mobile Connector and retry
What this alert means:
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot
identify the type of wall outlet the wall plug adapter is connected to, charge current is automatically reduced to 8A.
What to do:
1.
Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
2.
Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
a.
Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
b.
Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.
3.
Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
4.
If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully
connected to your Mobile Connector).
a.
If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b.
If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector. In the meantime, you can continue to charge with
the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition
persists.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle

When this alert is present, the electrical system cannot maintain the voltage required to support all vehicle features. Many vehicle functions may no longer work.
It is possible your vehicle may lose all electrical power. If this occurs, you can still use the manual door releases to exit the vehicle if necessary. For more information, see
Opening Doors from the Interior on page 14.
This alert may be present due to various vehicle conditions. For more information and further recommended actions,
check for other active vehicle alerts.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle
may not drive, may shut down unexpectedly, or may not restart.
VCFRONT_a192
Electrical system is unable to support all features
Switching off features to conserve energy
What this alert means:
The electrical system cannot support all vehicle features. Your vehicle is shutting down nonessential features to preserve energy for essential functions.
If you are driving when this alert is present, it is possible your vehicle may shut down unexpectedly. It is also possible
that your vehicle will not restart once parked.
Nonessential features may be unavailable, including seat heaters, cabin climate control, and in-vehicle entertainment.
This is expected behavior intended to help your vehicle maintain adequate electrical power for essential functions,
including the ability to operate headlights, windows and doors, hazard lights, and the front trunk (frunk).
It is possible your vehicle may lose all electrical power. If this occurs, you can still use the manual door releases to exit the vehicle if necessary. For more information, see
Opening Doors from the Interior on page 14.
What to do:
This alert may be present due to various vehicle conditions. For more information and further recommended actions,
check for other active vehicle alerts.
VCFRONT_a216
Vehicle may not restart - Service is required
Electrical system issue detected
What this alert means:
An abnormally large and sustained power draw while driving or Supercharging / DC Fast Charging has made your
vehicle

It is recommended that you schedule service at your earliest opportunity. Without service, your vehicle will remain
unable to restart, and the electrical system will remain unable to support all features and functions.
Some or all of the powered doors and windows in your vehicle may lose electrical power. If this occurs, you can still
use the manual door releases to exit the vehicle if necessary. For more information, see Opening Doors from the
Interior on page 14.
VCFRONT_a220
Electrical system is unable to support all features
Schedule service
What this alert means:
The low voltage battery is not available and cannot provide electrical support for vehicle features.
It is possible your vehicle will shut down unexpectedly. It is also possible that your vehicle will not restart after the
current drive.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
What to do:
It is recommended that you eliminate or reduce your use of any nonessential features. This can help your vehicle maintain adequate electrical power for essential functions other than driving, until it can be serviced.
If this alert remains present, it is recommended that you schedule service immediately. Without service, your vehicle
may not drive, may shut down unexpectedly, or may not restart.
VCFRONT_a402
Electrical system backup power is unavailable
Vehicle will consume more energy while idle
What this alert means:
The backup power source for the electrical system, the low voltage battery, is not available or cannot provide the
voltage required to support all vehicle features.
The primary source of electrical power, the high voltage battery system, will continue to support vehicle functions,
even when your vehicle is idle. For more information on the high voltage battery, see
About the High Voltage Battery
on page 167.
You may notice that some nonessential features are not available. This is expected behavior due to your vehicle
preserving energy for essential functions.
You may also notice that your vehicle consumes more energy than usual when you are not driving it, or that your vehicle displays a lower projected range than you would normally expect after charging. This is normal vehicle behavior when this alert is present, and it will continue until the backup power source is restored.
There is a chance that an issue affecting the primary power source could cause your vehicle to shut down
unexpectedly.
What to do:
It is recommended that you limit or avoid the use of any nonessential features. This can help your vehicle maintain
adequate electrical power for essential functions.
It is recommended that you schedule service at your earliest opportunity, so the backup power source for the
electrical system can be restored.
