Article C5.17.5
Car Operating Safety Status Signals
Chapter: C5
In Simple Terms
Every F1 car must constantly report its electrical power system (ERS) health status to the FIA's control systems. This information—covering battery insulation, voltage, temperature, and safety switches—helps officials monitor the ERS status lights and ensure the car is operating safely.
- Cars must continuously send safety status data to FIA ADR (technical control system)
- Status signals must monitor: insulation levels, battery cell voltage, battery temperature, contactors, and other defined systems
- These signals control the ERS status lights that indicate car electrical safety to officials
- Ensures real-time monitoring of the hybrid power system's operating condition
Official FIA Text
All cars must provide signals regarding the current car operating safety status to the FIA ADR in order to facilitate control of the ERS status lights. The status of the car must be based at least on the insulation measurement, cells voltage, cells temperature, contactors and the systems defined in C5.23.4.
