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.
Switches Affected By The External Door Handles
Two inner contact breakers are in each handle in the outer door handles. There is also a lock button in each handle. One of the contact breakers is connected to the handle. It is acted on by a linkage system if the handle is pulled out. The other switch is acted on if the lock button is pressed in. There is also a control arm between the door handle and the quick lock. The control arm acts on a third switch inside the quick lock if the handle is pulled out fully.
The first contact breaker is closed when the handle is pulled out by 2 - 4 mm. When a contact breaker is closed, an input on the keyless vehicle module (KVM) is grounded. The keyless vehicle module (KVM) wakes and activates the external antennas to scans for a valid remote key. This switch is closed for as long as the handles is pulled out.
Just before the handle is pulled out to its limit position, the switch in the quick lock is closed by the control arm from the door handle. When the switch closes, one of the inputs in the keyless vehicle module (KVM) is grounded.
This mechanical affect on the switch in the quick lock is one of the conditions for the keyless vehicle module (KVM) to activate the quick lock.
The switch connected to the lock button is closed when the lock button is pressed in. The switch instructs the keyless vehicle module (KVM) that the vehicle should be locked.
