Hybrid/EV Battery System Current High
What it means
The current flowing in or out of the hybrid/EV battery system is higher than the control module allows. The control module watches the current flowing in and out of the high-voltage battery to protect it and limit power.
Can I keep driving? Usually yes for a short trip, but power may be reduced or the car may stop without warning; get it read soon. Do not open high-voltage (orange) cables or covers yourself; leave that to a trained technician.
What this part does
The high-voltage battery pack is the large assembly of cells, wiring and sensors that stores the energy used to drive a hybrid or electric vehicle. The battery control system monitors it continuously and tells the rest of the vehicle how much power it can supply or accept. It carries dangerous voltage, so work on it is for trained people. Problems may cause a warning, reduced range or power, or a car that will not start.
