Tasks
The brake light switch detects the operation of the brake pedal. This signal is read in by the ESP control unit (N30/4) (without code (ZS6) Special protection version FB6 and without code (ZS7) Special protection version FB7) or from the ABS control unit (N47-7) (with code (ZS6) Special protection version FB6 or with code (ZS7) Special protection version FB7).
The detected operation of the brake pedal is redundantly sent over a direct line to the rear signal acquisition and actuation module (SAM) (N10/2).
