SERVICE: If a defect is found with the HVCH causing an isolation warning, before replacement of the HVCH perform a test of high voltage battery pre-charge contactor. This is to determine if the pre-charge resistor has been damaged. If the result confirms the pre-charge resistor is damaged, also replace the complete BDU. High voltage battery contactor test found in Vida as follow: Planning & Diagnostics->Components>ECUs->Battery Energy Control Module->Diagnostic Sequences If high voltage battery contactor test result is ok, please remove the MSD to prevent further stress on pre-charge resistor. After HVCH replacement please test the 3-phase AC Charging circuit to determine if the OBC has been damaged. This has to be done on an 11kW and above power charge station to utilize 3-phase charging. If a red indication is present in the EVI Charging Inlet, please follow fault tracing according to VIDA. HVCH = High Voltage Coolant Heater BDU = Battery Disconnect Unit MSD = Manual Service Disconnector OBC = On Board Charger EVI = Electrical Vehicle Inlet Warranty claim info: To get warranty claim accepted for a job described in this TJ, please use following data: VST OP number: 36050-2 VST OP number: 31130-2 36050-2 Calibrating/Identifying with VIDA 31130-2 High Voltage Battery, disconnecting and connecting VEHICLE REPORT: Yes, please submit a Vehicle Report if the service solution described in this TJ has no effect.
