|
|
An electric vehicle supply equipment (EVSE) using pulse width modulation (PWM) pilot reports that it has encountered an issue.
|
The EVSE sets the legacy pilot to the faulted state.
|
Charging does not start or is interrupted.
|
|
|
AC electric vehicle supply equipment (EVSE) communicating over single wire controller area network (SWCAN) reports that it has encountered an issue.
|
The EVSE reports via SWCAN that it has entered the faulted state.
|
Charging does not start or is interrupted.
|
|
|
The combined charging system (CCS) charging session is not started due to communication failures during the electric vehicle supply equipment (EVSE) discovery protocol (SDP).
|
The CP ECU detects that the SDP failed an unexpected number of times.
|
Charging does not start.
|
|
|
The power line communication (PLC) modem establishes communication successfully when it is expected to be depopulated.
|
The PLC modem responded when verifying that it is not populated.
|
Combined charging system (CCS) charging does not work.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the charge cable proximity did not latch within the expected timeframe.
|
The CP ECU detects that the charge cable proximity remains unlatched for longer than expected.
|
Charging does not start.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the electric vehicle supply equipment (EVSE) is still in an authentication state.
|
The EVSE spends longer than expected in the authentication state.
|
Charging does not start.
|
|
|
Communication times out between the charge port (CP) electronic control unit (ECU) and the electric vehicle supply equipment (EVSE).
|
The EVSE and the CP ECU cannot establish communication within the set timeframe between being connected and starting to charge.
|
Charging does not start.

|
|
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 power line communication relay (PLCRLY) is no longer receiving messages from the charge port (CP) electronic control unit (ECU). This alert is used only by PLCRLY.
|
PLCRLY does not receive messages from the CP ECU within 10 times their expected rate of transmission.
|
PLCRLYs on single-phase CP vehicles will not allow combined charging system (CCS) charging above 370A.
|
|
|
The charge port (CP) electronic control unit (ECU) detected that the Combined Charging System (CCS) Combo 1 Adapter temperature is higher than expected. The charging rate may be reduced.
|
The CP ECU detects that the CCS Combo 1 Adapter temperature is higher than acceptable operational range.
|
The charging rate may be reduced or charging may be unexpectedly interrupted.
|
|
|
The charge port (CP) electronic control unit (ECU) detects an unexpected rapid rise in temperature.
|
The CP ECU detects that thermal velocity, which is calculated each minute, exceeds the expected increase rate of temperature.
|
DC charging is terminated and is blocked until the charge cable is disconnected.
|
|
|
Thermistor input is open or short circuit.
|
The thermistor reports a voltage less than the open circuit threshold and, if short circuit detection is supported, greater than the short circuit threshold for at least one second.
|
Charging and heating functions do not work as expected.
|
|
|
The CHAdeMO adapter reports a temperature at which charging should stop.
|
The CHAdeMO adapter reports a temperature that is too high to continue charging.
|
Charging is unavailable.
|
|
|
The CHAdeMO adapter reports a temperature at which charging should begin to fold back.
|
The CHAdeMO adapter reports a temperature above the limit for steady state operation.
|
Charging speed is reduced.
|
|
|
The charge port (CP) electronic control unit (ECU) detects that the protective earth connection may be missing.
|
The CP ECU detects proximity voltage greater than 4.75V for more than 100ms.
|
Charging does not start.
|
|
|
The Gen 2 Wall Connector reports a temperature high enough that AC charging should begin to fold back.
|
The Gen 2 Wall Connector reports a temperature greater than 80 degrees C.
|
AC charging speed is reduced.
|
|
|
The charge port (CP) electronic control unit (ECU) detects unexpected voltage at the inlet harness identifier pins or is unable to identify the type of inlet harness.
|
The CP ECU detects unexpected voltage at the inlet harness identifier pins or is unable identify the type of inlet harness.
|
No expected impact on vehicle functionality. Other alert(s) indicating a specific condition affecting charging functionality may be present.
|
|
|
The charge port (CP) electronic control unit (ECU) is unable to confirm the state of the charging cable.
|
The CP ECU is unable to determine the state of the charge cable based on proximity and pilot circuits.
|
Charging may not start or may be interrupted. Before entering drive, confirm the charge cable is not connected to the vehicle.
