Summary
"SERVICE BULLETIN - THE VEHICLE MONITORS THE TEMPERATURE OF THE TWO POWER PINS ON THE CHARGING INLET OF THE VEHICLE. IF THE TEMPERATURE OF THE PINS IS EXCESSIVE OR THERE IS AN UNUSUAL TEMPERATURE DIFFERENCE BETWEEN THE PINS, THE VEHICLE WILL SET DTC P0D9A (CHARGE INLET TEMPERATURE SENSOR 1 RANGE/PERFORMANCE PROBLEM) AND OUTPUT THE PLUG-IN CHARGING SYSTEM PROBLEM MESSAGE ON THE MID. THE LATEST SOFTWARE HAS RAISED THE TEMPERATURE SPECIFICATION FOR CHARGE INLET HEATING DUE TO POOR CONTACTS ON THE EVSE. IF THE TEMPERATURE OF THE INLET RISES TO AN UNACCEPTABLE LEVEL, THE NEW SOFTWARE WILL ALLOW THE VEHICLE TO FINISH CHARGING AT A REDUCED CURRENT, WHICH WILL INCREASE THE CHARGING TIME. THE VEHICLE WILL STILL PROTECT ITSELF AGAINST EXCESSIVE HEAT THAT MIGHT DAMAGE THE CONNECTOR AND, IN EXTREME CASES, WILL SHUT DOWN THE CHARGING EVENT AND SET A DTC. IF THE VEHICLE ALREADY HAS THE LATEST SOFTWARE UPDATE AND STILL SETS THE DTC, THE CHARGE INLET CABLE ASSEMBLY MAY NEED TO BE REPLACED."
