THEFT DETERRENT SYSTEM (w/o Intrusion Sensor) - SYSTEM DESCRIPTION
| THEFT DETERRENT SYSTEM |
The theft deterrent system will operate when somebody attempts to forcibly enter the vehicle, unlock any door or luggage compartment door or open the engine hood or the luggage compartment door without using the key. This system causes the interior light to light up, hazard warning lights, headlights and taillights to blink and the vehicle horn and security horn to sound in order to deter break-in and theft.
The security indicator comes on or blinks to inform the driver that the alarm is set or not set.
The system locks all doors if any door is unlocked during the time that the alarm is activated.
The main body ECU RH controls this system.
