Switches Affected By The External Door Handles
The external door handles have two inner switches and a lock button as well as an antenna. One switch 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 switch is closed when the handle is pulled out by 2 - 4 mm. When a switch 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 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.
