Kia 0K2A167740 Relay

Some of the electrical accessories in the vehicle include the fuel injection system; horns; starter; and fog lamps Relays are used to transfer electrical signals to the parts by using a low current control circuit to handle a high current power circuit. A bad relay will cause a related component not to work correctly and a majority of them are placed in the engine compartment and interior fuse or relay boxes. If there is an indication of a faulty relay, it may be pulled and checked possibly from a certain procedure or from a specialist. Power circuits of most relays in these kinds of vehicles are ISO relays that can be easily distinguished by the presence of numbers on the terminals showing their Ci/Co/ai positions and roles, optimizing the layouts of which come in two main types of terminal planning. The control circuit is used to connect to the relay coil as the other terminals are in the power circuit where the power is energized by creating the magnetic field as made by the coil. Usually terminals 85 and 86 are for the control circuit and provided thereof since the configurations for the diode or resistor may require additional connection. Terminal 30 is the connection point to the battery positive terminal and terminal of 87 connects to the ground end of the circuit. For checking relay, ohmmeter can be used to measure the continuity through the control coil and should show proper resistance values and characteristics with respect to the presence of resistor or diode. Furthermore, continuity should be examined concerning the power circuit terminals when the relay is at a standby state, and with the energizing of the relay, continuity should be determined as to pin number 30 and 87. If any tests reveal a failure, the relay should be replaced.

Most of the electrical accessories in the vehicle use relays to supply the current for the certain component, and if the relay is faulty, then the particular component will not function as expected. Bulk of the relays are located in the engine compartment fuse and relay box; however, others can be found in the different wiring looms positioned beneath the instrument cluster. If a faulty relay is believed to exist, the part can be pulled and either taken through a set series of steps or brought to a dealer service department or repair shop, as bad relays are replaced as an assembly. Most of the relays employed in these vehicles are referred to as "ISO" relays, labeled with the terminal numbers to represent the common circuit configurations and applications. Two of the terminals are applicable to the relay control circuit and connecting to the relay coil, while the other is for the power supply. When energized, the coil produces a magnetic field that will close the larger contacts of the power circuit to supply power to the loads. Terminals 85 and 86 are generally the control circuit while other connections are expected if the relay contains a diode or resistor. Terminal 30 is typically connected to the battery voltage supply for the circuit loads, whereas terminal 87 connects to the ground side of the circuit. To check continuity through the relay control coil, we use the ohmmeter and be sure to check it both ways. If there is a resistor within the relay, the resistance should be the same in either direction but a diode is different because it will present high resistance in one direction than in the other. Any chance of resistance in both directions means that the relay must be changed. After the relay has been removed, there should be no continuity between the power circuit post when the switch is off and the post 30 and 87. Next, bringing a fused jumper wire to terminal 86 from positive battery terminal and another jumper wire connecting terminal 85 and ground should cause the relay to click and there should be continuity between the terminals 30 and 87. If the relay does not pass any of these tests, it should be replaced.
