Q: What does code P2C94 mean?

Hybrid/EV Battery Contactor Control Supply Circuit/Low. P2C94 indicates that the hybrid or electric vehicle battery contactor control supply circuit has a low voltage condition, meaning the battery energy control module has detected that the voltage feeding the contactor control circuit is below the expected threshold. This circuit is responsible for supplying power to the relays that connect and disconnect the high-voltage battery from the rest of the vehicle, so a low supply can prevent the contactors from closing or cause them to open unexpectedly.
