Antitheft and Alarm Systems: Description and Operation
Power is supplied at all times^ through 3O A fusible link (letter (B), located in the fusible link and fuse box)
^ to ignition switch terminal (1).
With the ignition switch in the START position, power is supplied
^ from terminal (5) of the ignition switch
^ to clutch interlock relay terminal (3) (M/T models) or
^ to theft warning relay-1 terminal (3) (A/T models).
With the ignition switch in the START position, power is supplied
^ from terminal (6) of the ignition switch (M/T models)
^ through 10 A fuse (No. (16), located in the fuse block)
^ to theft warning relay-1 terminal (3).
With the ignition switch in the ON or START position, power is supplied
^ through 10 A fuse (No. (26), located in the fuse block)
^ to theft warning relay-1 terminal (1).
Power is supplied at all times
^ through 10 A fuse (No. (20) located in the fuse block)
^ to theft warning control module terminal (1) and
^ to combination meter terminal (32).
Power is supplied at all times
^ through 10 A fuse (No. (17), located in the fuse block)
^ to trunk room lamp switch terminal (a).
With the ignition switch in the ACC or ON position, power is supplied
^ through 10 A fuse (No. (12), located in the fuse block)
^ to theft warning control module terminal (3).
Ground is supplied
^ to theft warning control module terminal (16)
^ through body grounds (M51), (M76) and (M77).
THEFT WARNING SYSTEM ACTIVATION (Without key used to lock front doors)
The operation of the theft warning system is controlled by the doors, hood and trunk lid.
To activate the theft warning system, the key must be removed from the ignition switch and the theft warning control module must receive signals indicating the doors, hood and trunk are closed and the doors are locked.
When a door is open, theft warning control module terminal (5) receives a ground signal from each door switch.
When a door is unlocked, theft warning control module terminal (9) receives a ground signal
^ from terminal (2) of the door unlock sensor
^ through body grounds (M51), (M76) and (M77) for the front doors and
^ through body grounds (B6) and (B14) for the rear doors.
When the hood is open, theft warning control module terminal (15) receives a ground signal
^ from terminal (1) of the hood switch
^ through body grounds (E12) and (E37).
When the trunk lid is open, theft warning control module terminal (14) receives a ground signal
^ from terminal (1) of the trunk room lamp switch
^ through body ground (T7).
If none of the described conditions exist, the theft warning system will activate automatically.
THEFT WARNING SYSTEM ACTIVATION (With key used to lock doors)
If the rear doors are locked and the key is used to lock either front door, theft warning control module terminal (7) receives a ground signal
^ from terminal (1) of the front LH or RH key cylinder switch
^ through body grounds (M51), (M76) and (M77).
If this signal is received by the theft warning control module, the theft warning system will activate automatically.
Once the theft warning system has been activated, theft warning control module terminal supplies ground to combination meter terminal (39) for the security lamp.
The security lamp will illuminate for approximately 30 seconds and then go out.
THEFT WARNING SYSTEM OPERATION
The theft warning system is triggered by
^ opening a door or the trunk lid without using the key
^ opening the hood
^ tampering with the key cylinder in the door or trunk lid.
Once the theft warning system has been activated, if the theft warning control module receives a ground signal at terminal (5), terminal (14) or terminal (15) (as described under THEFT WARNING SYSTEM ACTIVATION), the theft warning system will be triggered. Also, when one of the following signals is received at the theft warning control module, the system will be triggered. The head lamps flash and the horn sounds intermittently, and the starting system is interrupted.
When a door key cylinder switch has been tampered with, theft warning control module terminal (6) receives a ground signal
^ from terminal (3) of the front LH or RH key cylinder switch
^ through body grounds (M51), (M76) and (M77).
When the trunk key cylinder switch has been tampered with, theft warning control module terminal (6) receives a ground signal
^ from terminal (2) of the trunk key cylinder switch
^ through body ground (T7).
If the theft warning system is triggered, ground is supplied
^ from terminal (4) of the theft warning control module
^ to theft warning relay-1 terminal (2).
With power and ground supplied, power to the clutch interlock relay (M/T models) or inhibitor switch (A/T models) is interrupted. The starter motor will not crank and the engine will not start.
Power is supplied at all times
^ through 75 A fusible link (letter (E), located in fusible link and fuse box), and
^ through 10 A fuse (No. (35), located in fusible link and fuse box)
^ to theft warning relay-2 terminals (1) and (3), and
^ to theft warning relay-3 terminal (1).
Power is supplied at all times
^ through 15 A fuse (No. (37), located in fusible link and fuse box)
^ to theft warning relay-3 terminal (6).
Power is supplied at all times
^ through 15 A fuse (No. (36), located in the fusible link and fuse box)
^ to theft warning relay-3 terminal (3).
When the theft warning system is triggered, ground is supplied intermittently
^ from terminal (12) of the theft warning control module
^ to theft warning relay-2 terminal (2) and
^ to theft warning relay-3 terminal (2).
The headlamps flash and the horn sounds intermittently.
The alarm automatically turns off after 2 or 3 minutes but will reactivate if the vehicle is tampered with again.
THEFT WARNING SYSTEM DEACTIVATION
To deactivate the theft warning system, a door or the trunk lid must be unlocked with the key.
When the key is used to unlock a door, theft warning control module terminal (11) receives a ground signal from terminal (2) of the front LH or RH key cylinder switch.
When the key is used to unlock the trunk lid, theft warning control module terminal (10) receives a ground signal from terminal (1) of the trunk key cylinder switch.
When the theft warning control module receives either one of these signals, the theft warning system is deactivated.
