Direct Current To Direct Current Converter (G2165127): Operation

WARNING: This page is about a different variant/trim than selected.
WARNING: Do not do any work on the High Voltage (HV) electric system until the HV system on the vehicle is powered down.

The Direct Current to Direct Current (DC/DC) converter converts the high voltage Direct Current (DC) from the PHEV battery (more than 300V) to 12V DC. The DC/DC converter supplies all the vehicle 12V systems, the startup battery and the auxiliary battery. The DC/DC converter receives communications from the Body Control Module/Gateway Module (BCM/GWM) via the High Speed (HS) Controller Area Network (CAN) power mode zero systems bus. The BCM/GWM sends charging load requests and the DC/DC converter produces the correct output voltage and current to match the vehicle load requests.
