Brake light switch
Brake light switch |
The control module receives current on pin 23 via the brake light switch if the brakes are activated.
The brake light switch is also used if the road surface is extremely slippery and the driver chooses to pump the brakes.
Each time the driver depresses the brake pedal, i.e. when the control module receives current from the brake light switch, the ABS is reactivated from the starting position.
