Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Switch
The brake switch is located under the instrument panel, at the brake pedal arm. See Fig 1 . The brake switch has 3 internal switches controlling various functions of the vehicle. Its main function is to control operation of the vehicle's brakelights. Other functions include speed control deactivation, brake sense for the anti-lock brake system and brake sense for the brake transmission shift interlock. The switch can only be adjusted once. That is during the initial installation of the switch. If the switch is not adjusted properly or has been removed for some service, a new switch must be installed and adjusted.
