Engine Immobilizer:

The engine immobilizer is a state-of-the-art anti-theft system. After you insert your key into the electrical switch or bring a wise Key fob into the vehicle, the key transmits an electronic code to the vehicle. The engine will only start if the code within the transponder chip inside the key or Smart Key fob matches the code within the vehicle’s immobilizer. The transponder chip is embedded inside the key or Smart Key fob, it becomes costly to interchange it. If you lose a key or Smart Key fob, your dealer can help. Alternatively, you’ll find a certified independent locksmith to perform high-security key services by consulting your local mechanic or by contacting Associated Locksmiths.

Why Engine Immobilizer important?

What if you lose your car’s keyfob? All you’ve got to try and do is visit any authorized dealership to own it deactivated and request a replacement one. They’ll provide you with a replacement one as soon as they verify your credentials and pay a hefty price.

How does Electronic Engine Immobiliser work?

An advanced electronic Engine Immobiliser system within the latest cars uses rolling/changing security codes. this method featuring in BMW cars which consists of Two-Tier security. A permanent personal code and changing the second code. when the key starts the engine, the system changes the second code and stores it within the key. Whenever the motive force switches on the ignition, the immobilizer first reads the private code. Then, it requests for the second rolling code.

After both these codes match, only then the immobilizer sends another coded signal to the Engine Management System to unlock the engine. Without this, the engine doesn’t start. within the absence of the second security code, still, the engine won’t start whether or not someone tries short-circuiting the ignition circuit. Thus, it prevents vehicle theft.

Since the transponder chip is embedded within the key or Smart Key fob, it can not be easily duplicated. just in case of loss of the key or Smart Key fob, only the authorized dealers can deactivate the lost key. They will arrange for a brand new key from the manufacturer after verifying the customer’s credentials.

How does Engine Immobilizer Works?

The engine immobilizer is an anti-theft system in-built the engine ECU. It prevents the engine from starting without using the vehicle’s authorized key. this technique uses a special digitally coded key or a wise Key fob. This key contains a transponder chip. It stores the electronic security code or just the vehicle’s password. The ECU doesn’t activate the equipment and therefore the ignition circuit if the code within the key & that stored within the immobilizer doesn’t match.

When the driver force inserts this digital key into the switch or takes the Smart Key fob inside the vehicle, the key transmits the electronic code to the Engine Management System of the vehicle. The engine can start provided that the code within the transponder chip inside the key or Smart Key fob matches with the code within the engine immobilizer.

What is Automobile Auxiliary Power Outlet?

Automobile Auxiliary Power Outlet:

An automobile auxiliary power outlet in an automobile was initially designed to power an electrically heated ignitor but became a factual standard DC connector to produce power for portable accessories employed in or near an automobile, directly from the vehicle’s electrical system.In most vehicles, a minimum of one car outlet is present. Some vehicles, especially vans, tend to own more power outlets, usually one for the front passengers, another for the rear passengers, and one for the baggage trunk.The voltage of the facility outlet is sometimes near 12 V DC, (14V to 15V while the running engine is popping the alternator, to charge the automobile battery while providing electrical power) because it’s directly powered without regulation from the car’s electrical system.

Accessories:

Examples of devices which will be operated from an automobile power outlet include lights, fans, and little motorized tools like air compressors for inflating tires. Many portable electronic devices use an adapter connected to the car power outlet to recharge their internal batteries or to directly operate from the vehicle electrical system.Devices that need alternating-current mains electricity are often operated with a plug-in inverter, which produces output voltage usable by many electrical energy devices.Automobiles may provide several 12V receptacles that are intended only to control electrical accessories and can’t be used with an ignitor despite having the identical shape and diameter. Car manufacturers may offer an igniter only as an optional extra-cost accessory. Usually, only 1 12V receptacle near the driving force is meant for a cigar lighter, with other receptacles designated as “12 V auxiliary power outlets” not rated to be used with a lighter.Some vehicles provide 24 volts to the outlet, so some accessories carry a 24-volt rating.

Technical details:

The sockets and mating plugs are defined within the ANSI/SAE J563 specification. For the 12 volt systems, the middle contact is that the positive terminal, and therefore the shell is that the negative terminal. Most automobiles connect the negative terminal to the frame of the vehicle (negative ground).12-volt auto connectors are made to accommodate a regular by Underwriters Laboratories for safety. UL2089 was developed to hide the necessities for portable adapters rated 24 V DC or less that are intended to be supplied from the battery-powered electrical system of a vehicle. Products covered by the quality include cord assemblies of a plug that mates with the quality cigarette receptacle found in automobiles.6-volt light receptacle and plug• Receptacle inside diameter: 21.34–21.46 mm (median 21.4 mm)• Plug body diameter: 21.08–21.23 mm (median 21.155 mm)12-volt pocket lighter receptacle and plug, size A• Receptacle inside diameter: 20.93–21.01 mm (median 20.97 mm)• Plug body diameter: 20.73–20.88 mm (median 20.805 mm)12-volt pocket lighter receptacle and plug, size B• Receptacle inside diameter: 21.41–21.51 mm (median 21.455 mm)• Plug body diameter: 21.13–21.33 mm (median 21.18 mm)Plugs often include a pilot light LED indicator to point that electric power is connected. Optionally, the plug is also equipped with an enclosed fuse for electrical safety, usually rated at 10 amps or less. In some designs, the tip of the plug is also unscrewed to reveal a cylindrical glass fuse; other variants may use a blade-type fuse inserted into the side or back of the plug.
