Security Alarm System
System Description
The security alarm system is armed automatically after the doors, hood, and hatch are closed and locked. For the
system to arm, the ignition switch must be off and the key removed, and the security control unit must receive signals
that the doors, hood, and hatch are closed and locked. The alarm can be disarmed at any time by unlocking either door
with the key or the remote transmitter.
When everything is closed and locked, none of the control unit inputs are grounded (switches open). 15 seconds after
the doors are locked with the key or the lock knob, or immediately after locking the doors with the remote transmitter,
the system arms and the security indicator on the gauge assembly flashes.
If one of the switches is misadjusted or there is a short in the system, the system will not arm. As long as the control
unit continues to receive a ground signal, it senses that the vehicle is not closed and locked, and it will not arm.
Conversely, a switch that is slightly misadjusted can sound an alarm for no apparent reason. In this case, it may only
take a significant change in outside temperature, the vibration of a passing truck, or someone bumping into the
vehicle to make the alarm sound.
If anything is opened or improperly unlocked after the system is armed, the control unit receives a ground signal from
that switch. The system sounds the alarm when any of these things occur:
• The ignition switch is turned ON (II)
• A door is forced open
• A door or hatch is unlocked without using the key or the remote transmitter
• The hood is opened
• The hatch is opened
• The audio unit is removed
When the system sounds the alarm because of one of these violations, the security horn sounds and the headlight
(low beam), parking lights, taillights, and side marker lights flash for 120 seconds. The alarm then shuts off and the
system rearms. The alarm can be stopped by unlocking either door with the key or the remote transmitter.
When the panic button is pressed on the remote transmitter, the security horn sounds and the headlights (low beam),
parking lights, taillights, and side marker lights flash for 30 seconds. The alarm then shuts off, locks the doors, and
arms the system.

1. Remove the driver’s dashboard lower cover (see page 20-63).
2. Disconnect the 20P connector (A) and 16P connector (B) from the control unit (C).
3. Inspect all the connector and socket terminals to be sure they are all making good contact.
• If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
• If the terminals look OK, go to step 4.
