|
DC charging does not start.
|
|
|
The charge port inlet pin temperature has reached an unacceptable level (greatly exceeds normal operating range), causing DC charging to stop.
|
The charge port inlet pin temperature reaches a level where it is unacceptable to continue DC charging (temperature detected greatly exceeds normal operating range).
|
DC 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 (CP) electronic control unit (ECU) detects that the GB DC or AC protective earth (PE) busbar is missing.
|
The CP ECU detects that GB AC proximity voltage is greater than 4.75V for more than 100ms.
|
GB DC charging does not start.
|
|
|
The charge port (CP) electronic control unit (ECU) detects a reset was completed via a power cycle. This alert is for logging purposes and is set every time a power cycle occurs.
|
The CP ECU detects a reset occurred via power cycle.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the charge cable latch is disengaged when it is expected to be engaged, and may be frozen.
|
The CP ECU detects that the CP latch is not engaged after the vehicle is driven with the latch engaged and cold weather mode active.
|
The CP latch is frozen in the disengaged state, and as a result AC charging is limited and DC charging does not start.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the latch is not disengaged when it is expected to be disengaged, and may be frozen.
|
The CP ECU detects that the CP latch is not disengaged after the vehicle is driven with the latch disengaged and cold weather mode is active.
|
The CP latch is frozen in the engaged state, blocking cable insertion and removal.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an invalid MAC address.
|
The CP ECU detects that the MAC address is invalid.
|
Combined charging system (CCS) DC charging may not start.
|
|
|
The charge port (CP) electronic control unit (ECU) does not receive the expected Combined Charging System (CCS) vehicle to grid (V2G) messages within the expected timeframe.
|
The CP ECU does not receive the expected V2G messages.
|
CCS charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) is unable to communicate with the electric vehicle supply equipment (EVSE).
|
The CP ECU is unable to communicate with the EVSE.
|
DC fast charging may be unavailable at Combined Charging System (CCS) charge stations.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the Combined Charging System (CCS) charge session was aborted.
|
The CP ECU detects the CCS charge session was aborted.
|
CCS charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the charging session is taking longer to startup than expected and exceeds the maximum time frame.
|
The charging session does not start within the expected time frame.
|
CCS charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) is unable to read the received Combined Charging System (CCS) vehicle to grid (V2G) messages.
|
The CP ECU is unable to read the expected V2G messages.
|
CCS charging may not start or may be interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) reset the CP door inductive sensor due to a I2C communication or conversion error.
|
The CP door inductive sensor encounters a I2C communication or conversion error, causing the ECU to reset it.
|
The CP door may not function as expected.
|
|
|
The charge port (CP) electronic control unit (ECU) detects a conversion error on the CP door inductive sensor.
|
The CP door inductive sensor encounters a conversion error.
|
The CP door may not function as expected.
|
|
|
The Gen 2 Wall Connector reports a high temperature at which charging should stop.
|
The Gen 2 Wall Connector reports a temperature greater than 90 degrees C.
|
AC charging is unavailable.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that communication with the CP door inductive sensor has failed.
|
The CP ECU loses inter-integrated circuit (I2C) communication with the inductive door sensor, and attempts to reestablish communication have failed.
|
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.
