Safety Circuit

The safety circuit recognizes faulty signals inside and outside electronic control unit. Safety circuit intervenes in control sequence during extreme driving conditions, such as hydroplaning. When fault is recognized, system is switched off. The condition is indicated to driver by illumination of the warning light.

The safety circuit continuously monitors battery voltage. If voltage is less than specified requirements, system is switched off until voltage is within specified range. In addition to the monitoring function, safety circuit also includes active test cycle section or BITE (Built In Test Equipment).
