What it means

P0D8E is a generic powertrain code meaning the control unit has detected a high voltage or high signal state on control circuit C for the battery charger coupler status indicator. This relates to the indicator that shows the state of the charge inlet or coupler on plug-in hybrid and electric vehicles. The module that drives the indicator saw a circuit reading above the expected range, which suggests a short to voltage or a fault in the driver. Which circuit is designated C and how it is wired depends on the vehicle manufacturer and model.

Symptoms

Charge status indicator at the charge port stays on, stays off or behaves erratically
Charging will not start or stops unexpectedly
Warning light or message about the charging system on the dash
Charge port lock or coupler status not recognised
Plug-in hybrid or EV running in a reduced mode or not showing a charge state

Possible causes

Short to voltage on the indicator control circuit wiringlikely
Damaged, corroded or contaminated connector at the charge port or indicator assemblylikely
Faulty charge port or coupler indicator assembly, such as an internal LED driver or circuit faultpossible
Water ingress or debris in the charge inlet affecting the indicator circuitpossible
Fault in the charger or controlling module driver circuitpossible
Outdated or faulty control unit software where the manufacturer has issued a fixrare

How to diagnose

Read all stored and pending codes and note freeze frame data, including any other charging or high voltage related codes
Check for relevant technical service bulletins and software updates for the specific model
Visually inspect the charge port, indicator and surrounding area for damage, moisture, corrosion or burnt contacts
Inspect the wiring and connectors between the charge port and the controlling module for chafing, pin damage and signs of water
Using the manufacturer's wiring diagram for the model, check the control circuit C for a short to voltage and check the supply and ground
Check the indicator control with a scan tool that supports bidirectional tests, if the vehicle allows it, and see whether the circuit state follows the command
Clear the code and recheck with the charge cable connected and disconnected to see whether the fault returns
Follow the manufacturer's high voltage safety procedures before touching any orange high voltage components, and only work on them if trained

How to fix

Repair or replace the damaged wiring that is shorted to voltage
Clean, repair or replace corroded or damaged connectors and terminals
Replace the faulty charge port or indicator assembly
Dry out and repair the water ingress and replace any parts that are damaged
Replace or update the controlling module only when testing shows a fault in its driver and the manufacturer specifies it, or apply a manufacturer software update if one covers this fault

Can I keep driving?

Low severity

The vehicle can usually be driven, as this is an indicator circuit fault, but charging may be affected so book it in soon. If there are other high voltage or charging warnings, or you see signs of burning or water at the charge port, stop using the charger and have it checked.
