Summary
"CHANGE TO PHEV HV BATTERY CELL MODULES. INFORMATION There has been a change to all Generation 3 PHEV high-voltage (HV) battery cell modules. The number of temperatures sensors on the cell modules has decreased from 4 sensors to 3 sensors. This change has to be taken into account when replacing a component within the HV battery that requires the charging or discharging of a cell module with the Deutronic DBL1200HV-60 cell module charger. When connecting the cell module to the charger the number of temperature sensors (NTC's) will need to be changed to 3 for the charger to charge the module correctly. Refer to the DBL1200HV-60 manual for more information (Attached). To verify how many temperature sensors are on the cell module use the ""Diagnosis"" function of the DBL1200HV-60 cell module charger. The example to the right shows 3 temperature sensors. The message ""ZKS not connected"" will be displayed if the incorrect amount of temperature sensors (NTC's) is selected."
