5.5.8.1 Initial Situation
 ControlPilot_ChargeMode is set to mode B.
 Vehicle_IsolationMeasurementRequest is set to activated.
 The VC-EVCC sets the following CAN signals initially and after any end of a V2G
sequence to the specified values:
 VCVCCU_V2G_DateTimeNowFlag to 0 (FALSE)
 VCVCCU_V2G_EVSECurrentRegulationToleranceFlag to 0 (FALSE)
 VCVCCU_V2G_EVSEEnergyToBeDeliveredFlag to 0 (FALSE)
 VCVCCU_V2G_EVSElsolationStatusFlag to 0 (FALSE)
 VCVCCU_V2G_EVSEMaximumCurrentLimitFlag to 0 (FALSE)
 VCVCCU_V2G_EVSEMaximumPowerLimitFlag to 0 (FALSE)
 VCVCCU_V2G_EVSEMaximumVoltageLimitFlag to 0 (FALSE)
 VCVCCU_Vehicle_ContactorRequest to 2 (ForceOpen)
5.5.8.2 Charge Error Detection
The VC-EVCC provides a charge error detection. Therefore, the following Diagnostic
Trouble Codes (DTC) are used to indicate missing information or invalid conditions which
are needed for charging.
