P0D2C is set for a fault in the driver circuit of charge status indicator A, the light that tells the driver whether the car is charging. On the Chevrolet Volt that light is part of the diagnosis itself: bulletin PIP4905E has technicians watch whether the charge indicator on the instrument panel stays steady green. GM tests the driver for a ground short while the LED is commanded on and for a short to battery or an open circuit while it is off, needing 40 bad readings out of 50 at 100 ms. Volt 2011 and 2012 set the code as Type B, with the MIL on the second trip; the 2016 ELR tables use One Trip Type A. A broken wire, a failed LED or a corroded plug are typical. Charging still works, but the owner loses the visual confirmation. A second indicator B uses P0DE5.
Medium severity. Can I keep driving?If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
