|
No
|
|
|
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.
|
No
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the latch is not in the blocking position when it is expected to be.
|
The latch position sensor indicates that the latch is disengaged after the CP attempts to engage the latch fully, or if the latch is expected to be blocking cable insertion.
|
The latch does not block cable insertion when it is expected to.
|
No
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the vehicle is connected to a Supercharger post that is updating.
|
The Supercharger post reports to the vehicle that it is updating.
|
Supercharging is unavailable at that post.
|
No
|
|
|
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.
|
No
|
|
|
Lost comms with VCFRONT
|
Charge port does not receive all expected CAN messages from the VCFRONT
|
Charging may not start, charge port door and latch may not actuate, charge port LEDs may not turn on
|
No
|
|
|
The charge port (CP) latch is expected to be engaged but is not engaged. AC charge rate may be reduced, and DC charging may be unavailable.
|
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.
|
The charge port (CP) latch may not engage as expected. AC charge rate may be reduced, and DC charging may be unavailable.
|
No
|
|
|
Charge port (CP) latch is expected to be disengaged but remains engaged. Charge cable may become stuck, or user may be unable to insert charge cable.
|
The charge port (CP) latch position sensor indicates the latch is still engaged or blocked after the charge port has attempted to disengage the latch.
|
The charge port (CP) latch may not disengage, charge cable may become stuck, or user may be unable to insert charge cable.
|
No
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the latch has been manually disengaged.
|
The CP ECU detects that the latch transitions to the disengaged state from the engaged or blocking state without actuating it.
|
Charging is interrupted.
|
No
|
|
|
Latch calibration data is unavailable.
|
EEPROM indicates that the latch offset is not valid for more than 1 second.
|
The CP ECU may not be able to detects the latch position correctly, and the latch may not engage or disengage.
|
No
|
|
|
Charge port (CP) door is expected to be closed but is still open.
|
Charge port (CP) door is not detected as closed, even after it has been commanded to close.
|

|
Charge port (CP) door is not detected as open, even after it has been commanded to open.
|
Charge port door may not open correctly.
|
No
|
|
|
The charge port (CP) door is closed but the CP electronic control unit (ECU) still senses pilot voltage and/or proximity voltage in an unexpected range.
|
