Vehicle Security System Deactivation

To deactivate the vehicle security system, a door must be unlocked with the key or keyfob.

When the key is used to unlock the door, smart entrance control unit terminal 10 receives a ground signal:

• Through front door key cylinder switch LH terminal 3
• Through front door key cylinder switch LH terminal 2
• Through body grounds M14 and M68.

When the smart entrance control unit receives this signal or an unlock signal from keyfob, the vehicle security system is deactivated (disarmed phase).
