AC charging may not be operational on the next attempt. DC fast charging should remain functional.
|
|
|
The vehicle controller detects that precharging the high voltage (HV) DC bus may be unsuccessful, which may lead to the inability to close the HV contactors and a complete loss of vehicle power. Charging vehicles with GB (charging standard used in China) charge ports requires opening and closing the HV contactors.
|
The vehicle controller detects that precharging the HV DC bus may be unsuccessful.
|
If GB DC charging is attempted, the charge session may fail, the HV contactors may not close again, and there may be a complete loss of LV power.
|
|
|
The charge port (CP) electronic control unit (ECU) is reading irrational values from the CP door hall effect sensor located in the CP door, which may prevent the CP door from opening when pressed.
|
The CP ECU detects irrational values from the hall effect sensor in the CP door that are outside of the expected range.
|
The CP door may not open when it is pressed.
|
|
|
The charge port inlet pin temperature has reached an unacceptable level (greatly exceeds normal operating range), causing AC charging to stop.
|
The charge port inlet pin temperature reaches a level where it is unacceptable to continue AC charging (temperature detected greatly exceeds normal operating range).
|
AC charging will be interrupted and remain unavailable until a charge cable cycle occurs (disconnect and reconnect) and the charge port inlet pin temperature returns to normal operating range.
|
|
|
The charge port inlet pin temperature has reached a level where limiting AC charge current is necessary until temperature returns to normal operating range.
|
The charge port inlet pin temperature reaches an unexpected level (temperature detected exceeds normal operating range).
|
AC charge current is limited.
|
|
|
The Charge Port (CP) Electronic Control Unit (ECU) is unable to detect the control pilot signal due to an internal condition on the CP ECU. Charging may be unavailable.
|
The CP ECU is unable to receive the expected control pilot signal waveform due to an internal condition on the CP ECU.
|
Charging may be unavailable during the next charge attempt.
|
|
|
The charge port (CP) electronic control unit (ECU) detects the control pilot voltage is outside of the nominal range while using Tesla electric vehicle supply equipment (EVSE), indicating an internal condition on the CP ECU.
|
The CP ECU detects the control pilot voltage did not go below -10V while using Tesla EVSE.
|
AC charging may be unavailable during the next charging session. No expected impact on Supercharging functionality.
|
|
|
The Combined Charging System (CCS) charge station reports that it has experienced an unrecoverable error. Charging may not start or may be interrupted, with a charge cable cycle (disconnect, then reconnect to vehicle) required before charging can start or resume.
|
The Combined Charging System (CCS) charge station sends a message indicating it has experienced an unrecoverable error.
|
Charging may not start or may be unexpectedly interrupted. A charge cable cycle (disconnect, then reconnect to vehicle) is required before charging can start or resume.
|
|
|
The Power Line Communication (PLC) modem application for the Charge Port (CP) electronic control unit (ECU) does not load after a maximum number of automatic retries. DC fast charging will be unavailable at Combined Charging System (CCS) charge stations.
|
The Power Line Communication (PLC) modem application does not load after multiple consecutive attempts / maximum number of retries.
|
DC fast charging will be unavailable at Combined Charging System (CCS) charge stations.
|
|
|
