What are the functions and testing procedures for relays on Chevrolet Impala?

Some of the electrical accessories found in a car include the fuel injection system horn-starter fog lamps and much more that use relays to pass electrical signals to them. Relays are devices which have a low current control circuit to switch a high current power circuit. A defective relay will cause the associated component not to work as it is supposed to work. Almost all the relays are fixed in the engine compartment fuse/relay box, but a few select relays are in the interior fuse box well above the dashboard. If a faulty relay is believed to exist, it must be removed, and tested by following some procedure or taken directly to a dealer service department or a repair shop and any faulty relay must be replaced in its entirety. In these vehicles, most relays are ISO relays; they have numbered terminals, giving information about typically used circuits and their functions, and two terminal configurations. The wiring diagram of the circuit might assist in pointing the right connections that have to be made for testing purposes. Two terminals of the relay are used in the control side of the coil while the other two terminals are found in the power side of the relay. Whenever it is energised, the coil produces a magnetic field to make the larger contacts of the power circuit close to supply power to the loads. The control circuit is usually formed by the terminals 85 and 86; if a diode is provided, the terminal 86 goes to the battery positive voltage, and the terminal 85 - to the ground, and the resistor enables the terminals 85 and 86 are interchangeable. There is also another terminal to handle the rest of battery voltage for circuit loads identified as terminal 30 while terminal 87 is to where a component that is to be energized is to be connected while the other terminals that may be 87A, 87B and so on are the backup terminals. To confirm continuity through the relay control coil there is always the use of an ohmmeter which should ideally be checked with both polarities. But if a resistor is used, the resistance should be the same in each direction of operation while a diode Normally a diode will offer higher resistance in the forward polarity direction. Coil resistance of both first and second relays to zero and infinite indicating the relays should be replaced. When the relay is unscrewed and disconnected, continuity should be found between the power circuit terminals and at the same time, there should be no continuity found between terminal 30 and 87 when the circuit power connection is disconnected. By connecting a fused jumper wire to terminal 86 and the positive battery terminal, and another jumper wire between terminal 85 and the negative terminal of the battery the relay should make a clicking sound. With these connections, it should now be possible to establish continuity between terminals '30 and '87. In the case that the relay does not pass any of these tests, it is advised that it is replaced.
