Brake Switch - TCC: Description and Operation
CIRCUIT DESCRIPTION
This signal is used to detect when the brakes have been applied. The BK signal voltage is the same as the voltage supplied to the stop lights.
The BK signal is used mainly to control the fuel cut-off engine speed. (The fuel cut-off engine speed is reduced slightly when the vehicle is
braking.)
