P0D88Battery Charger Coupler Status Indicator Control Circuit A High
- Generic OBD-II code · Powertrain
- How the car detects it
- P0D88 is stored when channel A of the charge port status indicator sits at a high level although the driver is holding it off, typically because the line touches a voltage-carrying wire or the driver stage leaks. The fault is therefore seen in the switched-off state; GM's Volt evaluated its own charge-status LED (P0D2C) for short to battery only while the LED was meant to be dark. No manufacturer documents P0D88 publicly. The visible result is often the reverse of P0D87: channel A glows constantly or faintly, so the port may suggest a charging state that does not exist. A pinched harness at the flap hinge, a bridged connector or a defective output in the control module are the causes to check. Charging works normally; P0D86 and P0D87 cover open and grounded faults of the same channel.
