press UNLOCK on either door lock switch or turn the key to the unlock position from the
passenger door key cylinder switch.
All Door Lock: The multifunction alarm module locks all of the doors when you press

All Door Unlock
The multifunction alarm module unlocks all of the doors when you press UNLOCK once
on either the door lock switch or on the keyless remote.
Pressing UNLOCK once on either door lock switch connects ground to the multifunction
alarm module. When the circuit is grounded it cycles the door lock actuator control
circuit from a normally grounded circuit to battery positive voltage. This supplies power
to the door lock actuators and receives ground from the multifunction alarm module.
All Door Lock
The multifunction alarm module locks all of the doors when you press LOCK once from
either door lock switch with both front doors closed, or turn the key to the LOCK
position from either door key cylinder switches.
Lockout Prevention
The multifunction alarm module does not lock the vehicle doors when you press LOCK
on either door lock switch with the lockout prevention feature active. The multifunction
alarm module activates the lockout prevention feature when the following conditions
exist:
• Either front door is open.
• The key is inserted in the ignition switch cylinder.

• All door lock
