Door Lock Features
The multifunction alarm module has the following door lock features:
All Door Unlock: The multifunction alarm module unlocks all
of the doors when you 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 LOCK on either door lock switch.
Lockout Prevention: The multifunction alarm module does not
lock the doors if you press LOCK on either door lock switch if the key is in the
ignition cylinder and the driver and or the front passenger door is open.
Driver Door All Unlock: The multifunction alarm module unlocks
all of the vehicle doors when you turn the key to the UNLOCK position twice in quick
succession from the driver door key cylinder switch.
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. |
The multifunction alarm module disables the following automatic door lock features:
| • | Last door closed locking |
| • | Keyless entry system lock function |
Anti-Theft Operation
The Anti-theft function disables the door unlock function of the door lock
switches when one of the following actions occur:
| • | The ignition key is removed, and with the driver door open, the LOCK
switch is pressed from either door switch. |
| • | With the ignition key removed and all doors closed, you press the LOCK
button on the keyless entry transmitter. |
To disable the anti-theft function, one of the following actions must occur:
| • | Turn the key to the UNLOCK position from either door key cylinder switches |
| • | Press the UNLOCK button on the keyless entry transmitter |
| • | Cycle the ignition switch. |
