Charge Status Indicator A Control Circuit/Open
What it means
The charge status indicator A control circuit is open, meaning the module sees a broken or disconnected path. This indicator tells the driver or charger side about charging state, so the fault is usually a signalling problem rather than a drive problem.
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 charge status indicator is a light, often on the dashboard or near the charging socket, that shows the charging state of a plug-in hybrid or electric vehicle. A control module switches it to show states such as plugged in, charging or fault. If it fails, the light may be off or show the wrong state, even when charging works normally.
