DC/DC Enable (DCE)

WARNING: This page is about a different variant/trim than selected.

The DCE is an output from the PCM to the DC/DC converter. The PCM enables the DC/DC converter after the PCM receives a contractors closed message and no error messages. The DCE circuit is high (the low side driver is off) when the DC/DC is commanded on. When the DCE low side driver is activated, the DC/DC converter is commanded off. For additional information on DCE, refer to the DC/DC converter description in HYBRID ELECTRIC CONTROL HARDWARE .
