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.
Circuit/System Description
The exterior door handle switch signal circuit provides inputs to their respective door lock/window switch when the exterior door handle switch is activated. This input allows the door lock/window switch to detect a door open request. The door lock/window switch provides voltage to the exterior door handle switch via the front door handle switch signal circuit. When the front door handle is activated, the switch closes and the voltage signals from the door lock/window switch are pulled to ground.
