P0D32
DC/DC Converter A Over Temperature
Generic OBD-II
What it means
DC/DC converter A is running hotter than its limit. The DC/DC converter steps high-voltage battery power down to charge the 12-volt system and run accessories.
Can I keep driving? Usually yes for a short, gentle trip, but heat can damage the battery or drive parts; if power drops or a warning shows, stop and get it checked. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.
