Vehicle Security System Activation (With Key or Electronic Key)

VEHICLE SECURITY SYSTEM ACTIVATION (WITH KEY OR ELECTRONIC KEY USED TO LOCK DOORS)
If the emergency key is used to lock doors, LCU01 terminal No.10 receives a ground signal
- from terminal No.3 of the driver door key cylinder switch.
- through body grounds No.M24 and No.M114

If this signal or lock signal from electronic key is received by BCM, the vehicle security system will activate automatically.

Once the vehicle security system has been activated, BCM terminal No.65 supplies ground to terminal No.19 of the security indicator lamp.

The security lamp will illuminate for approximately 30 seconds and then blink. Now the vehicle security system is in armed phase.

VEHICLE SECURITY SYSTEM ALARM OPERATION
The vehicle security system is triggered by
- opening a door
- opening the trunk lid
- opening the hood
- unlocking door without using the electronic key.

The vehicle security system will be triggered once the system is in armed phase,
- when BCM receives a ground signal at terminal No.33, No.37, No.142, No.143 (door switch), No.146 (trunk room lamp switch) or No.122 (hood switch)
- when driver door LCU receives a ground signal at terminal No.6 (driver door unlock sensor)
- when passenger, rear LH, RH door control unit receives a ground signal at terminal No.13 (passenger, rear LH, RH door unlock sensor) Power is supplied at all times
- to head lamp relay-1 terminal No.2 and
- through 15A fuse (No. 56, located in fuse block (J/B) No.1)
- to horn relay terminal No.2.

When the vehicle security system is triggered, ground is supplied intermittently
- from BCM terminal No.5 (lamp relay) and No.127 (horn relay)
- to head lamp relay terminal No.1 and
- to horn relay terminal No.1.

The head lamps 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.
