Brake Lamp Switch Circuit

BRAKE LAMP SWITCH CIRCUIT
An input from this switch prepares the CAB for a possible antilock stop.

The antilock system uses an input signal from the brake pedal activated switch. With the brake pedal not applied, a ground is fed through the brake lamp switch to the CAB on the Brake Lamp Switch Sense Circuit. When the driver applies the brake pedal the ground signal is interrupted, alerting the CAB of a possible ABS event.
