Scion 84340-32050 Stop Lamp Switch

The brake light switch is located on a bracket at the top of the brake pedal. For 2009 and earlier models, remove the left front door threshold trim plate, the cowl side trim panel, and the two lower trim panels. For 2010 and later models, remove the two screws and the instrument panel lower cover plate. Disconnect the wiring from the brake light switch, loosen the lock nut if equipped, and then unscrew the switch from its bracket. Installation is the reverse of removal. To adjust, check and, if necessary, adjust the brake pedal height. Loosen the switch locknut and adjust the switch so that the clearance between the switch body and the pedal is appropriate. If unable to measure this distance, adjust the plunger so that it lightly contacts the pedal stop, then tighten the locknut if equipped. Plug the electrical connector into the switch and reconnect the battery, ensuring the brake lights come on when the brake pedal is depressed and go off when released. If not, repeat the adjustment procedure until the brake lights function properly.
