The fuel injection system, horns, starter, and fog lams along with many other features passing electricity in the vehicle come with relays. Relays work in such a way that a low current control circuit is used to open and close a high current power circuit. Malfunctioning relays will render a linked component useless and while most relays are in the engine box fuse and relay compartment, some are near the passenger box fuse that can only be seen after moving the knee bolster. If it is assumed that the relay is faulty then it can be pulled out forPossible tests or taken to a dealer service department because relay cannot be rebuilt and it has to be substituted. Relay that is commonly used in these vehicles is normally an NO relay. By tracing the schematic of the obtained apparatus and comparing it to the intended circuit, the correct connections for testing can be made. There are two terminals reading the relay control circuit and the other two joining the relay coil; the other two form the power circuit. When energized the coil creates a magnetic field heavy enough to close the extra large contacts of the power circuit supplying powers to the loads of the circuit. To inspect the relay that is normally open, it is necessary to make a measurement with the ohmmeter without connection and with connection of the terminals No. 3 and No. 4 to the power and the ground, respectively, with the check on the terminals No. 1 and No. 2. However, if the relay will not jump this test, then it will have to be replaced.

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.

The installation is the reverse of the removal process.
