|
An EVSE using legacy pilot has faulted.
|
The EVSE sets pilot to the faulted state
|
Charging may not start or may be interrupted unexpectedly.

|
|
Charging session not started due to communication failures during the EVSE discovery protocol (SDP) which occurs during CCS charging.
|
The SDP failed an unexpected amount of time
|
Charging may not start
|
|
|
Charging session cannot begin because the EVSE is still in authentication state.

The EVSE spent an unexpected amount of time in the authentication state
|
Charging session may not start
|
|
|
Indicates that communication between the EVSE and the CP timed out.
|
Timer between establishing communications with EVSE and starting charge expires
|
Charging will not start
|
|

Messages from CP are not received within 10x their expected transmit rate.
|
North America PLCRLYs may not allow CCS charging above 370A.
|
|
|
The Power-Line Communication (PLC) relay detected that the Combined Charging System (CCS) Combo 1 Adapter temperature is higher than expected. The charging rate may be reduced.
|
The PLC relay 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 Power Line Communication Relay (PLCRLY) modeled adapter temperature has entered a region where its thermal foldback limits are dynamically changing.
|
The PLCRLY modeled adapter temperature hits its active threshold.
|
DC charge current may be limited.
|
|
|
The Power Line Communication (PLC) modem successfully booted its application but first required the Power Line Communication Relay (PLCRLY) electronic control unit (ECU) to reset.
|
The PLC modem application responds to a request from the PLCRLY ECU, but the PLCRLY ECU had to reset the PLC modem first because the first load attempt was unsuccessful.
|
This alert is primarily informational and is used for logging purposes. No expected impact on vehicle functionality.
|
|
|
The Power Line Communication (PLC) modem application 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.
|
|
|
During a DC fast charging session at a Combined Charging System (CCS) charging station, the Electric Vehicle Supply Equipment (EVSE) detects low isolation resistance.
|
The CCS DC EVSE detects low isolation resistance during a charging session.
|
CCS charging may not start or may be interrupted.
|
|
|
The GTW configuration for PLC support does not match the hardware installed in the vehicle.
|
Configuration of the GTW PLC support type does not match the Charge Port configuration
|
The GTW will not update the PLC modem and PIB during OTA updates
|
|
|
Invalid MAC address written to CP genealogy.
|
MAC address stored in genealogy is invalid
|

|
|
|
The Power Line Communication Relay (PLCRLY) electronic control unit (ECU) does not receive the expected Combined Charging System (CCS) vehicle to grid (V2G) messages within the expected time frame.
|
The PLCRLY ECU does not receive the expected V2G messages.
|
CCS charging may not start or may be interrupted.
|
|
|
The vehicle is unable to communicate with the electric vehicle supply equipment (EVSE).
|
The vehicle is unable to communicate with the EVSE. The PLCRLY ECU is unable to communicate with the EVSE.
|
Combined charging system (CCS) DC charging may not start. DC fast charging may be unavailable at Combined Charging System (CCS) charge stations.

|
|
The Power Line Communication Relay (PLCRLY) electronic control unit (ECU) detects the Combined Charging System (CCS) charge session has ended.
|
The PLCRLY ECU detects the CCS charge session has ended.
|
CCS charging may not start or may be interrupted.
|
|
|
The Power Line Communication Relay (PLCRLY) 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 Power Line Communication Relay (PLCRLY) electronic control unit (ECU) is unable to read the received Combined Charging System (CCS) vehicle to grid (V2G) messages.

The PLCRLY ECU is unable to read the expected V2G messages.
|
CCS charging may not start or may be interrupted.
|
|
|
The Power Line Communication Relay (PLCRLY) detects the control pilot signal remains in state B1, indicating the charge station is connected to the vehicle but is not ready to charge the vehicle, for too long while a charge cable is plugged into the Charge Port (CP).
|
PLCRLY detects charge handle proximity as connected to the CP without pressing the charge handle button, and control pilot signal is detected in state B1 for more than five seconds.
|
