Battery Charger Coupler Status Indicator Control Circuit B High
What it means
The battery charger coupler status indicator control circuit B is reading higher than the module expects. The charge port status indicator shows the state of the plug and charging, and the charger controls it through this circuit.
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
The coupler status indicator is a light at the charging socket that shows charging state, for example connected, charging or fault. The charger control module switches it to give the driver a visual cue. The socket connects to high voltage, so service is for trained people. A fault may leave the light dark or incorrect even if charging works normally.
