Door Lock Cylinder Switch

The front door lock cylinders are equipped with switches. The switches are used in order to disarm the CTD system. When you turn the lock cylinder in order to unlock the door, the following actions occur:
^ The door lock cylinder switch closes.
^ The RFA module detects a ground at terminal E11 (CKT 262, LT GRN).

When the RFA detects a ground condition at terminal E11, the CTD system is armed and the system enters delayed mode.
