What it means

P0D95 is a generic powertrain code meaning the control unit has detected an open circuit in the control circuit for the battery charger coupler unlock function. This relates to the mechanism that releases or locks the charge connector on a plug-in hybrid or electric vehicle. The control unit commanded the unlock actuator or monitored its circuit and saw no current flow or an open-circuit voltage, so it set the fault.

Symptoms

Charging cable will not release from the vehicle charge port
Vehicle will not start charging, or charging stops early
Charge port warning light or charging system message on the dashboard
Malfunction indicator lamp or hybrid system warning on
Charge port lock or unlock does not click or operate when the button or key is used

Possible causes

Open circuit or damaged wiring between the control unit and the charge port unlock actuatorlikely
Corroded, loose or pushed-out pins in the charge port or actuator connectorlikely
Faulty charge coupler lock/unlock actuator with an open internal windinglikely
Blown fuse or loss of supply to the actuator circuitpossible
Water ingress or physical damage at the charge portpossible
Fault in the charging control unit or the driver inside itrare

How to diagnose

Read all stored codes and freeze frame data, noting whether other charging or charge port codes are present and when the fault set
Check for any relevant software updates or service bulletins for the specific model, as the circuit layout varies by manufacturer
Visually inspect the charge port, its seals and the connector for water, debris, corrosion, heat marks or damage
Check the fuse and supply for the actuator circuit using the wiring diagram for the vehicle
Inspect the wiring harness from the charge port to the control unit for chafing, breaks or pin damage, and check connector pin tension
Using a wiring diagram, test the actuator circuit for continuity and resistance with the connector disconnected and the high voltage system made safe
Command the unlock actuator with a diagnostic scan tool function test, if supported, and confirm the actuator responds
Clear the code and retest by cycling the lock and unlock function to confirm the fault does not return

How to fix

Repair or replace damaged wiring and restore the open circuit
Clean, repair or replace corroded or damaged connectors and terminals
Replace the charge port lock actuator or charge port assembly if it has failed
Replace the blown fuse after finding and fixing the cause of the overload or loss of supply
Dry out and reseal the charge port area, replacing damaged seals
Replace or reprogram the control unit only after the wiring and actuator have been proven good

Can I keep driving?

Medium severity

The car can usually still be driven if the charge cable is released, but charging may not work and the fault should be fixed soon. If the cable is stuck in the port, use the manufacturer's manual release procedure and do not force it, as the high voltage system is involved.
