What is the purpose of relays in a Subaru Impreza's electrical system?

There are several electrical accessories in the car including relays that relay electrical signal to the component like fuel injection system, horns, starter and fog lamps. Relays use control circuit (low-current circuit) to open and close power circuit (high-current circuit). If there is something wrong with such relay, the part will not work properly. Most of the relays are located in an engine compartment fuse and relay box. Besides, some relays may be found on or near a passenger's compartment fuse box but they are hidden behind knee bolster which can only be removed. Simply remove it if you suspect a faulty relay and test it using procedure below. Or have the dealer service department test it for you. They cannot repair defective relays; therefore; they must be replaced with new ones. The majority of these vehicles' relays are normally open type of relays. The relay coil connects two terminals which are also called as the control circuit for relay while other ones form its power circuit. When the relay is energized, it causes generation of magnetic field by a coil that would close its larger contacts through which power flows to loads located across circuits. In order to test a normally-open type of relay, turn off any source of power at terminal No 1 and then check if there is no continuity between terminal No 2 at this time using an ohmmeter device make sure that there is continuity between terminal No 1 when terminals No 3 & 4 connected with sources of power and ground respectively. Replace this particular one should it fail such examination as described above.

Subaru Impreza Relay

The primary function of the Subaru Impreza Relay is to act as an electrically controlled switch that allows low power signals to control the higher current components of the climate system. In the A/C circuit, this Relay is placed between control modules and devices such as the fan or blower motor so that if it fails, the connected device loses power immediately rather than becoming an intermittent fault. The Subaru engineers applied the familiar electromechanical Relay that works using an internal electromagnet that snaps contacts open or shut to effectuate the Relay switch. However, later versions also include solid state Relay versions that use semiconductors and have no moving parts, which cuts noise and wear. The latching Relay locks in after one pulse and remains in that position when the voltage drops, making sure that the Impreza will not be affected by climatic surprises during brief power interruptions. All styles have the same simple structure for control and output to load, two signals in every case. The manner in which the contacts are moved or held differs among styles. By pinpointing the root cause, because one little part is responsible for stopping the airflow and preventing Subaru owners from spending money on unnecessary motors, the air-conditioning of the Impreza will be comfortable all year round.
