P0D87Battery Charger Coupler Status Indicator Control Circuit A Low
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D87 flags channel A of the charge port status indicator as pulled low, which in practice means a short to ground somewhere between driver and lamp. Such a fault only shows when the channel is switched on: the driver tries to raise the line and current flows straight to ground. GM's Volt checked its comparable charge-status LED (P0D2C) exactly that way, with 40 failed samples out of 50 taken every 100 ms while the LED was commanded on. No maker publishes thresholds for P0D87 itself. Chafed insulation on a body edge, water that has entered the inlet lighting or a shorted LED module are the usual suspects. Most drivers protect themselves by switching off, so the light stays dark; charging is not affected. An open circuit on the same channel is P0D86, a short to voltage P0D88.
