Brake-light switch
Brake-light switch |
When the brake pedal is depressed, current is fed via the brake-light switch to pin 14 on the control module.
Information on the status of the brake-light switch (ON/OFF) is used by the electronic brake-force distribution function (EBD) during pump-motor testing and ABS modulation.
Each time the brake pedal is depressed, i.e. the control module receives current from the brake-light switch, ABS control reverts to the default mode.
