P0D8D Battery Charger Coupler Status Indicator Control Circuit C Low

Drive cycleNot required
Limp modeNo

P0D8D marks channel C of the charge port status indicator as shorted toward ground: when the module switches C on, the line does not reach the expected level and the driver registers overcurrent or a low voltage. As with A and B, the code is defined in the standard but no manufacturer publishes its own conditions for it; GM's Volt logic for P0D2C, which tests a grounded LED line only while the LED is commanded on, shows the usual principle. Because the third channel is often the last LED or segment in a chain, damage tends to sit at the far end of the harness inside the inlet housing. A grounded driver output inside the module is the rarer case. Expect the channel to go dark and possibly the whole indicator to be disabled for protection; charging stays possible. P0D8C and P0D8E complete the C trio.

Likely causes

Short to ground at the far end of the harness inside the inlet housing
Shorted LED or segment of channel C
Grounded driver output inside the control module

Symptoms

  • Colour or segment C stays dark
  • Whole port indicator may switch off
