Vehicle Security System Deactivation
WARNING: This page is about a different car, the 2006 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
To deactivate the vehicle security system, a door or trunk lid must be unlocked with the key or keyfob.
When the key is used to unlock the door, smart entrance control unit terminal 30 receives a ground signal:
- from terminal U of front door key cylinder switch LH
- to terminal E of front door key cylinder switch LH
- through body grounds M28 and M54.
When the key is used to open the trunk lid, smart entrance control unit terminal 42 receives a ground signal:
- from terminal + of the trunk lid key cylinder switch (unlock switch)
- to terminal - of the trunk lid key cylinder switch (unlock switch)
- through body grounds B13 and B19.
When the smart entrance control unit receives either one of these signals or unlock signal from keyfob, the vehicle security system is deactivated. (Disarmed phase)
