What it means

P0D8C is a generic powertrain code meaning the control unit has detected an open circuit in the control circuit for the battery charger coupler status indicator. This is the indicator on or near the charge port that shows the plug or charging state on a plug-in hybrid or electric vehicle. The module commands the indicator but sees no expected current or voltage response, so it sets the code. The exact circuit layout and which module controls it depend on the model.

Symptoms

Charge port status light does not illuminate or stays off during charging
Warning light on the dashboard, such as a powertrain or charging system warning
Charging may be interrupted, refused or behave erratically
Charge status not shown correctly on the dash or app
Fault stored with no obvious change in driveability

Possible causes

Open circuit, broken wire or high resistance in the wiring to the charge port indicatorlikely
Corroded, loose or damaged connector at the charge port or control modulelikely
Failed charge port indicator LED or lamp assemblylikely
Damaged or water-ingress-affected charge port or coupler assemblypossible
Blown fuse or loss of supply or earth to the indicator circuitpossible
Fault within the charger control module or driver circuitrare
Outdated control module software where the manufacturer has issued a correctionrare

How to diagnose

Read all stored codes and freeze frame data, noting whether other charging or high voltage codes are present
Visually inspect the charge port, its seals and the surrounding area for damage, moisture, debris or corrosion
Check the relevant fuse and the supply and earth to the indicator circuit using the wiring diagram for the model
Inspect the connectors at the charge port and control module for bent pins, green corrosion or poor terminal tension
Command the indicator on using the scan tool's active tests, if supported, and observe whether it responds
Check the wiring for continuity and short to earth or supply, with the connectors disconnected and the vehicle in a safe, de-energised state
Check the indicator or port assembly resistance or operation against the manufacturer's specification
Check for software updates or technical bulletins for the model, then clear the code and retest while charging

How to fix

Repair or replace the damaged wiring section and secure it properly
Clean, repair or replace faulty connectors and terminals
Replace the charge port indicator or coupler assembly if it has failed
Replace a blown fuse after finding and correcting the cause
Update the control module software only if a known fault applies to this model
Replace the control module only after the wiring and indicator are proven good

Can I keep driving?

Low severity

The car can normally be driven as the fault affects the charge indicator rather than propulsion. Book it in soon, as charging may be affected and any high voltage work must be done by a suitably trained technician.
