How do electrical circuits utilize relays to transmit signals and what steps should be taken if a relay is suspected to be faulty on Cadillac Escalade?

Many electric circuits in the vehicle apply the use of relays to provide electrical signals to components, using a low-amp control circuit to regulate a high-amp power circuit. A defective relay will serve as an impediment to the optimum performance of the linked component; most of these relays are in the engine part fuse/relay container, while others are in the specialized interior fusable link override encompassing the fuse box in the dash. If a faulty relay is suspected, it can pulled out and examined using a particular method, or by a dealer service department or a repair shop, and a faulty relay must be in its entirety. Most of the relays used in the vehicles under analysis are ISO relays and they are numbered to illustrate the connections and the functions of the respective circuit; two typical configurations of terminals are present. The other terminals of the control circuit makes contact with the relay coil The power circuit makes contact with the other part of the coil making it provide magnetic field to close the larger contacts which supplies power to the circuits load. Speakers Terminal 85 and 86 are normally utilized for control circuit though additional connection is stipulated depending on the presence of diode or resistor. Terminal 30 is linked to the battery voltage supply while terminal 87 is linked to the device that is being supplied power with other terminals available as links for other connections. For checking the relay the continuity through the control coil can be checked using an ohmmeter and appropriately low resistance in one direction and high resistance in the other direction should be indicated if the latter is found to be of infinite resistance then it should be replaced. When the relay is unsoldered, there is no continuity between the terminals of the power circuit while there is continuity between terminals 30 and - when the circuit is energized and no continuity between these two terminals when the circuit is de-energized. Putting an end to this discussion, applying a fused jumper wire from the terminal number 86 and the positive terminal of Battery and another from number 85 to any ground point should make the relay click; the continuity between terminals number 30 and 87 should further be checked. Any testing would show that the relay had failed and it should then be changed.
