C1161 Hyundai Description
The brake light switch indicates brake pedal status to the ABS control unit. The switch is turned on when the brake is applied. The brake light switch is a normally-open contact which runs to battery voltage when active (brake operated). When passive (brake not operated), the cable is grounded via the brake light bulbs. The brake light switch is not monitored if the valve relay drops out, or in the event of low voltage or overvoltage.
