1. Unlocking switch, which indicates that the handle has been pulled out
2. The switch in the quick lock which enables the keyless vehicle module (KVM) to activate the motor in the quick lock.

When the quick lock switch is activated, a timer starts. The counter stops and is reset when the handle is released. The diagnostic trouble code (DTC) is stored if the keyless vehicle module (KVM) registers that the right front quick lock switch has been activated for more than 5 minutes.
