Laymans terms

This code means that the car's computer has detected a problem with the part that locks the plug when you charge the car. It's like when a toy's battery door doesn't close properly, so the toy won't work right.

Explanation

The P0D93 code indicates a high voltage condition in the control circuit responsible for locking the battery charger coupler. This can prevent the vehicle from charging properly.

Technical description

The Battery Charger Coupler Lock Control Circuit is responsible for ensuring that the charging plug is securely locked into the vehicle's charging port during charging. A 'high' condition suggests that there is an unexpected high voltage reading in this circuit, which could be due to a wiring issue, a faulty lock actuator, or a problem with the control module.

Symptoms
