P0D8E Battery Charger Coupler Status Indicator Control Circuit C High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P0D8E is recorded when channel C of the charge port status indicator shows a high level that the driver did not command, a short to a supply voltage or a driver that no longer turns off. Following the pattern GM published for the Volt's charge-status LED, this is checked while the output is meant to be inactive. No manufacturer documents P0D8E publicly. What the owner sees depends on what C signals on that vehicle: in multi-colour designs, where each LED colour carries a meaning such as fault, charging or complete, a constantly lit C channel can display a fault or a finished charge that is not real. Look for chafing where the harness passes the flap mechanism, a connector bridged by water or a stuck output stage. Charging is unaffected. P0D8C and P0D8D are the open and low faults of channel C.

Likely causes

Chafed channel C wire touching a supply wire at the flap mechanism
Connector bridged by water
Output stage in the control module stuck on

Symptoms

  • Colour or segment C lit permanently
  • Port shows a fault or complete status that is not real
