Battery Charger A Coupler Lock Position Sensor Circuit Range/Performance
What it means
The battery charger A coupler lock position sensor circuit is reading outside the range the module expects or not matching what it should. The sensor reports whether the charge plug latch is locked or released, which the charger needs before it starts charging.
Can I keep driving? Usually yes, as this mostly affects charging; get it read if charging fails. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.
What this part does
This sensor reports whether the lock holding the charging plug in the vehicle's charging socket is locked or released. The charger control module uses it to make sure the plug is secure before charging starts, and to release it when charging ends. The socket connects to high voltage, so service is for trained people. A fault may prevent charging or release of the plug.
