|
Push-to-open does not work, and the charge port does not detect that the high voltage (HV) inlet is covered by the CP door.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an error during a charge session with a Guobiao direct current (GB DC) charging station, causing the charge session to be aborted.
|
The CP ECU detects an error during a GB DC charging session.

GB DC charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an under voltage condition on the internal 3.3V power supply.
|
The internal 3.3V power supply voltage measured by the CP ECU is below 3.05V.
|
The charge port may not function as expected.
|
|
|
Vehicle is connected to an offboard CHAdeMO charging station, or CHAdeMO Electric Vehicle Supply Equipment (EVSE), that is not supported.
|
The CP detects a connection to unsupported CHAdeMO EVSE.
|
Charging will not start
|
|
|
The charge port (CP) has detected a missing control pilot signal while a charge cable is connected, which usually indicates the charge station does not have power. Charging may not start, and it may be necessary to try a different charge station.
|
Proximity is detected with no control pilot signal and no digital communications, and the vehicle is not charging.
|
Charging may not start.
|
|
|
Charge port (CP) expects the cable to be secured, but the charge port latch has not secured the cable in place. AC charge rate may be reduced, and DC charging may be unavailable.
|
A charge cable is detected. The charge port (CP) latch position sensor indicates the latch is disengaged, either after the charge port has attempted to engage the latch or when the latch is already expected to be engaged.
|
AC charge rate may be reduced, and DC charging may be unavailable.
|
|
|
Control pilot signal from charging station is lost while charging. Charging may be interrupted.
|
Proximity is detected with no control pilot signal and no digital communications while the vehicle is charging.
|
Charging may be interrupted unexpectedly.
|
|
|
Proximity circuit was opened unexpectedly while charging. Charging may be interrupted.
|
The charge port (CP) detects that there is no charge cable present while the vehicle is charging.
|
Charging may be interrupted unexpectedly.
|
|
|
The charge port (CP) detected that button was pressed on the charge cable connected to the Combined Charging System (CCS) Combo 1 Adapter.
|
The charge handle proximity changed to the unlatched state indicating a button press.
|
The Combo 1 charge cable may become unsecured or damaged.
|
|
|
The charge port (CP) electronic control unit (ECU) will delay an attempt to AC charge.
|
The CP ECU detects that the electric vehicle supply equipment (EVSE) has encountered an issue too many times while AC charging.
|
Charging does not start or is interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) is unable to establish single wire controller area network (SWCAN) communications. .
|
The CP ECU cannot establish SWCAN communications after multiple attempts.
|
Charging does not start or is interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) loses communication with the power conversion system (PCS).
|
The CP ECU does not receive all expected CAN messages from the PCS.
|
AC charging does not start.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the ultra-high frequency (UHF) receiver is missing (MIA).
|
The CP ECU receiver no longer receives serial peripheral interface (SPI) communications from the UHF receiver.
|
The CP door cannot be opened with the Tesla charge handle button.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the vehicle is connected to a Supercharger post that is out of service.
|
The Supercharger post reports to the vehicle that it is out of service.
|
Supercharging is unavailable at that post.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the vehicle is connected to a Supercharger post that is updating.
