Power Door Lock Switches

The power door lock switches are used to either arm or disarm the CTD system. Pressing the lock position will cause the CTD to arm after all doors are closed and the 30 second delay period has elapsed. Pressing the unlock position with the CTD system in any mode except ARMED will cause the CTD system to enter the disarm mode.

IMPORTANT
The CTD system can be armed with the windows or sunroof open.
