CP_a010
Charging equipment communication error
Try again or try different equipment
What this alert means:
Your vehicle is unable to charge because it cannot communicate effectively with the external charging equipment. It cannot
sense a valid control pilot signal coming from the charging equipment.
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.
What to do:
First, confirm the lack of effective communication is caused by the external charging equipment rather than an issue with your
vehicle. This is usually the case.
Try charging the vehicle using different external charging equipment (including charge cable, charging station, or charging
stall).
• If the vehicle begins charging, the issue was likely with the equipment.
• If the vehicle still does not charge, the issue may be with the vehicle.
If the issue is suspected to be with the vehicle, inspect the charge port inlet and the charge cable connector for any
obstructions, such as debris, moisture, and/or foreign objects. Make sure any charge port inlet obstruction has been removed
and any moisture has been allowed to dry, then try re-inserting the cable into the charge port.
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's touchscreen display. See Maps and Navigation on page 144 for more details.

accurately sense the charge port door position and the charge port may not operate as expected.
•
The charge port latch may intermittently remain engaged when the charge port door is opened.
•
The charge port light may illuminate only intermittently when the charge port door is opened.
What to do:
Try closing the charge port door and then opening it again.
