Toyota 84340-09070 Switch Assy, Stop Lamp

Removal and installation note, The lock nut of the brake pedal adjustment is located at the top of the brake pedal, not the switch. A bracket at the top of the brake pedal holds the brake light switch. Loosen the locknut then unscrew the switch from its bracket. Remove the lower panel fastener on driver's side before unclipping and removing it. Disconnect a wiring harness at a brake light switch. In 2013 and earlier models, loosen the locknut and unscrew the switch from the pedal bracket. In 2014 and later models, rotate this counterclockwise and remove it from a bracket. Insert stoplight switch until threaded end contacts pedal stop. For 2013 or older models, plug in electrical connector then move on to next procedure. On 2014 and later models, rotate clockwise to connect electrical connector then clockwise to connect electrical connector To reverse remainder installation for removal use below information provided above for direction. Adjustment for 2013 and earlier models, Check for proper height of brake pedal one should do this by loosing up locknut of switch so that it plunger protrusion falls within desired range as provided by manufacturer. Where unable to measure this distance adjust plunger so that it lightly engages with pedal stop Tighten up on locknut once done Hereafter, plug in an electric connector into your switches Ensure that when you press on your brake pedals, they show lights "ON" but are "OFF" when you release them; otherwise adjust again until bulbs function satisfactorily Check free play of your brake pedals if need be.

The brake light switch is situated on a bracket near the top of the brake pedal and activates the rear brake lights when the pedal is pressed. To check its functionality, observe if the brake lights illuminate when the pedal is pressed and turn off when released; if they do not, first check the fuse. If the lights remain unresponsive, the issue may lie with the switch not receiving voltage, a defective switch, or a faulty circuit between the switch and the lights, though it's unlikely that all brake light bulbs are burned out. Use a voltmeter or test light to confirm voltage at one side of the switch connector; if absent, troubleshoot the circuit from the switch to the fuse box. If voltage is present, check the other terminal while the brake pedal is pressed; if absent, replace the switch, and if present, troubleshoot the circuit leading to the brake lights. To replace the brake light switch, unplug the electrical connector, rotate the switch counterclockwise about a quarter turn to detach it from the bracket, and reinstall by reversing the removal steps, ensuring proper self-adjustment upon installation. For the brake light switch adjuster bracket, remove the switch from the bracket, press the two plastic adjuster clips inward, and pull the adjuster out of the metal bracket, with installation following the reverse of removal.

The brake light switch is on the brake pedal bracket, under the steering column panel. It controls the brake light circuit. If brake lights fail, check the fuse and bulbs first. If they're okay, check the switch's voltage. No voltage indicates an open circuit between the fuse block and switch. To replace, remove the panel, unplug the connector, rotate the switch counterclockwise, and remove. Install in reverse order.

First of all, pedal height refers to the brake pedal's distance from the floor. If it's not within the specified range, inspect the brake pedal, pedal arm, mounting bracket, and dash panel for damage. Adjust the brake light switch if necessary. To measure pedal height, start the engine, press the accelerator, and measure with the carpet pulled back and the pedal pad removed. Pedal free-play is the slack before the brake system is engaged. If incorrect, adjust the brake light switch or check the brake system. Pedal reserve height is the pedal's distance from the floor when fully depressed.

Disconnect the connector, rotate the switch 90° counterclockwise, and remove it. Install the new switch by pushing it in until it touches the rubber stop, then rotate to lock and reconnect the connector.

The brake light switch is located on the brake pedal bracket.
