DESCRIPTION




1. Operation Flow

2. Setting the Theft Warning System
Initial condition
1. Close all doors.
2. Close hood.

Disarmed phase
The theft warning system is in the disarmed phase when any door(s) or hood is opened. The security indicator lamp blinks every second.

Pre-armed phase and armed phase
The theft warning system turns into the "pre-armed" phase when hood and all doors are closed and the doors are locked by key or multi-remote controller. (The security indicator lamp illuminates.)
After about 30 seconds, the system automatically shifts into the "armed" phase (the system is set). (The security indicator lamp blinks every 2.6 seconds.)

3. Canceling the Set Theft Warning System
When the doors are unlocked with the key or multi-remote controller, the armed phase is canceled.

4. Activating the Alarm Operation of the Theft Warning System
Make sure the system is in the armed phase. (The security indicator lamp blinks every 2.6 seconds.)
When the following operation 1) or 2) is performed, the horn, theft warning horn and head lamps operate intermittently for about 2.5 minutes. (At the same time, the system disconnects the starting system circuit.)
1. Engine hood or any door is opened before unlocking door with key or multi-remote controller.
2. Door is opened without first using key or multi-remote controller.

POWER SUPPLY AND GROUND
Power is supplied at all times
- through 7.5 A fuse [No.28, located in the fuse block (J/B)]
- to security indicator lamp terminal 1.
Power is supplied at all times
- through 30 A fusible link [letter f, located in the fuse and fusible link box (with KA24DE engine)] or
- through 40 A fusible link [letter f, located in the fuse and fusible link box (with VG33E engine)]
- to circuit breaker terminal +
- through circuit breaker terminal -
- to smart entrance control unit terminal 1.
With the ignition switch in the ACC or ON position, power is supplied
- through 7.5 A fuse [No.20, located in the fuse block (J/B)]
- to smart entrance control unit terminal 17.
With the ignition switch in the ON or START position, power is supplied
- through 7.5 A fuse [No.5, located in the fuse block (J/B)]
- to smart entrance control unit terminal 11.
Ground is supplied
- to smart entrance control unit terminal 10
- through body grounds M14 and M68.

INITIAL CONDITION TO ACTIVATE THE SYSTEM
To activate the theft warning system, the smart entrance control unit must receive signals indicating the doors and hood are closed and the doors are locked.
When a door is open, smart entrance control unit terminal 15, 16 (crew cab) or 35 receives a ground signal from the corresponding door switch.
When the front door LH is unlocked, smart entrance control unit terminal 12 receives a ground signal from the front door lock actuator LH (door unlock sensor).
When the front door RH is unlocked, smart entrance control unit terminal 13 (2 door early production models) receives a ground signal from the front door lock actuator RH (door unlock sensor).
When the hood is open, ground is supplied
- to smart entrance control unit terminal 29
- through hood switch terminal +
- through hood switch terminal -
- through body grounds E12 and E54.
When the doors are locked with key or multi-remote controller and none of the described conditions exist, the theft warning system will automatically shift to armed phase.

THEFT WARNING SYSTEM ACTIVATION (WITH KEY OR REMOTE CONTROLLER USED TO LOCK DOORS)
If the key is used to lock doors, ground is supplied to smart entrance control unit terminal 30
- through front door key cylinder switch LH terminal 1 or
- through front door key cylinder switch RH terminal 3
- through front door key cylinder switch LH or RH terminal 2
- through body grounds M14 and M68.
If this signal or lock signal from remote controller is received by the smart entrance control unit, the theft warning system will activate automatically.
Once the theft warning system has been activated, smart entrance control unit terminal 33 supplies ground to security indicator lamp terminal 2.
The security lamp will illuminate for approximately 30 seconds and then blink. The theft warning system is now in armed phase.

THEFT WARNING SYSTEM ALARM OPERATION
The theft warning system is triggered by
- opening a door
- opening the hood
Once the theft warning system is in armed phase, if the smart entrance control unit receives a ground signal at terminal 12 (door unlock sensor) 13 (door unlock sensor, 2 door early production models) 15, 16 (crew cab),
35 (door switch) or 29 (hood switch), the theft warning system will be triggered. The horn, theft warning horn and headlamps operate intermittently and the starting system is interrupted.
With the ignition switch in the ON or START position, power is supplied
- through 7.5 A fuse [No.5, located in the fuse block (J/B)].
- to theft warning relay terminal 2.
If the theft warning system is triggered, ground is supplied
- to theft warning relay terminal 1
- through smart entrance control unit terminal 32.
With power and ground supplied, starter motor circuit is interrupted. The starter motor will not crank and the engine will not start.
Power is supplied at all times
- through 7.5 A fuse (No.31, located in fuse and fusible link box)
- to theft warning lamp relay terminal 2 and
- to theft warning horn relay terminals 2 and 7.
When the theft warning system is triggered, ground is supplied intermittently
- to theft warning lamp relay terminal 1 and
- to theft warning horn relay terminal 1
- through smart entrance control unit terminal 8.
The horn, theft warning horn and headlamps operate 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 must be unlocked with the key or remote controller.
When the key is used to unlock the door, smart entrance control unit terminal 31 receives a ground signal
- through front door key cylinder switch LH terminal 3 or
- through front door key cylinder switch RH terminal 1
- through front door key cylinder switch LH or RH terminal 2
- through body grounds M14 and M68.
When the smart entrance control unit receives this signal or an unlock signal from remote controller, the theft warning system is deactivated (disarmed phase).

PANIC ALARM OPERATION
Multi-remote control system may or may not operate theft warning system (horn, theft warning horn and headlamps) as required.
When the multi-remote control system is triggered, ground is supplied intermittently
- to theft warning lamp relay terminal 1 and
- to theft warning horn relay terminal 1
- through smart entrance control unit terminal 8.
The horn, theft warning horn and headlamps operate intermittently.
The alarm automatically turns off after 30 seconds or when smart entrance control unit receives any signal from multi-remote controller.
