TESLA MODEL Y 2023 Owners Manual

Reduced braking performance is usually temporary, and can occur for a number of reasons including high brake
temperatures after heavy brake use, or driving in extremely cold or wet conditions. It can also indicate that your
brake pads or rotors have worn to the point that normal replacement is needed.
If you continue to experience reduced braking performance which does not improve over time, please contact Tesla
service at your convenience for a brake inspection.
For more information, see Hydraulic Fade Compensation on page 66.
PCS_a016
Cannot charge - Poor grid power quality possible
Retry / Try other charge location or Supercharging
What this alert means:
Charging has stopped due to a condition that prevents your vehicle from charging with AC power. DC fast charging /
Supercharging should still function as expected.
This may be due to power supply disturbances caused by the external charging equipment or by the electrical
power grid. In some cases, this condition may be the result of using nearby electric devices that draw a lot of power.
If these possible causes can be ruled out, then a condition with your vehicle itself may also be affecting AC charging.
What to do:
If this alert is accompanied by another alert that specifies the condition affecting AC charging, start by investigating
that alert.
Further troubleshooting tips based on equipment type:

What to do:
This alert is often accompanied by other alerts that can help you identify and troubleshoot the issue. Start by
investigating any other displayed alerts that relate to charging issues.
Alternatively, you can check Mobile Connector or Wall Connector status lights to confirm power to the device, and
also refer to the product owner

PCS_a052
External charging equipment not providing power
Check power source or try different equipment
What this alert means:
Charging cannot begin due to a condition that prevents your vehicle from charging with AC power. DC fast charging / Supercharging should still function as expected.
Your vehicle has requested AC power from the external charging equipment, but the onboard charger does not detect any supply voltage coming from the equipment.
This can sometimes be caused by a hardware issue specific to the external charging equipment, which prevents the
charging equipment from switching power to the vehicle on or
off when requested. It could also occur due to
another condition
affecting the external charging equipment, the power source it is connected to, or your vehicle
itself.
What to do:
This alert is usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
Try charging with multiple, different types of charging equipment.
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

UI_a137
Active service connection to vehicle
Service performing remote diagnostics
What this alert means:
A service technician is remotely logged into your vehicle for diagnosis or repair. You may notice some loss of
Infotainment functionality while the connection persists, but this alert does not indicate an issue with your vehicle.
Your vehicle is OK to drive.
What to do:
This alert should clear automatically after the technician completes vehicle diagnosis or repair. You may find it
necessary to restart your touchscreen to restore full Infotainment functionality after the alert has cleared.For more
information, see Restarting the Touchscreen in your vehicle

The vehicle cannot charge because the ground-fault circuit interrupter (GFCI) in the Mobile Connector has tripped.
Like the GFCI in a wall outlet, this feature is designed to stop the flow of electricity when there is a problem. It has
interrupted charging to protect your vehicle and the charging equipment.
This could happen for many reasons. The problem could be in the charge cable, the charge handle, the charge port,
or even an onboard vehicle component.
What to do:
Inspect the charge port and the charge handle for pooled water or unusual levels of moisture. If you find excessive
moisture, wait and let both the inside area of the charge port and the exposed portion of the charge handle dry
sufficiently before trying again.
Inspect the charge equipment for damage.

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
