Read the chapter summary below:

Summary

■ A security system is designed to help prevent theft of the vehicle and its contents.

■ Security systems designs vary tremendously so thieves are not able to learn about the operation of any one system too well.

■ A transponder key contains an electronic chip that sends a coded signal to a module. If the module recognizes the signal, it allows the engine to be started.

■ Some theft deterrent systems use a resistance key which places a small electrical resistor in the side of the ignition key.

■ Navigation systems use our nation’s satellite global positioning system to display the geographic location of the vehicle.

■ A vehicle tracking system is a security system that can track, or follow, the location of a car or truck if it is stolen.

■ A night vision system uses an infrared camera and monitor system to help the driver view through vision-impairing atmospheric conditions.

■ A voice-activated system uses a microphone and computer data to perform functions by reacting to spoken words.

■ A collision avoidance system uses radar to detect a vehicle or other object in front of the vehicle.

■ An automatic parking system uses computer control to back up, steer, and brake a car into a parking space.

■ Servicing vehicle security and navigation systems usually involves part replacement however, the trouble may be a bad antenna or power feed problem to the unit.
