Q: What does code P2C92 mean?

Hybrid/EV Battery Contactor Control Supply Circuit/Open. P2C92 indicates that the hybrid or electric vehicle battery pack's main contactor control supply circuit has an open circuit, meaning the battery energy control module cannot detect the expected voltage or continuity on that control path. The computer sets this code when the contactor control supply circuit fails to provide the necessary power or ground to the contactor coil driver, preventing the high-voltage contactors from closing and isolating the battery pack.
