P0D94Battery Charger Coupler Lock Control Circuit Performance

P0D94 indicates that the battery charger coupler lock control circuit is not performing as expected, meaning the powertrain control module (PCM) has detected an abnormal voltage or current signature on the lock actuator circuit. The PCM commands the lock to engage or release during charging events, and it monitors the circuit for open, short, or out-of-range conditions that fall outside the manufacturer's calibrated window.
