ABS/TCC Switch and Stoplamp/BTSI Switch

The ABS/TCC switch (cruise release switch) and stoplamp switch are provided in order to disengage the cruise control. The switches are mounted on the brake pedal bracket assembly. Each switch consists of two switch contacts. The normally-closed TCC switch (part of the ABS/TCC switch) opens when the brake pedal is pressed, and closes when the pedal is released. The normally-open stoplamp switch (part of the stoplamp/BTSI switch) closes when the brake pedal is pressed, and opens when the pedal is released.

Pressing the brake pedal disengages the cruise control, causing the throttle to return to the idle position.
