P254FEngine Hood Switch Circuit
General electrical fault on the engine hood (bonnet) switch circuit. The hood switch tells the body controller and (on hybrids) the high-voltage system that the hood is open — used for security, alarm and HV-safety interlock. With the input invalid, alarm logic and HV interlock fall back to a safe state.
