FAQ:
Q: What does an ECM wiring relay do?
A: The ECM power relay is the relay responsible for sending power to the ECM. If the relay fails, or has any issues, it can cause the vehicle to have all sorts of problems, and may even render it undriveable. Usually a problem with the ECM power relay will produce a few symptoms that can alert the driver of a problem that should be serviced.
Q: What is an Arduino relay module?
A: Relay module for Arduino is one of the most powerful application for Arduino as it can be used to control both A.C and D.C devices by simply controlling the relay by giving 5V. A relay is basically a switch which is operated electrically by electromagnet.
Q: What is an electrical wiring diagram?
A: A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
Q: What is an electrical relay switch?
A: Electrical relays are electrical switches that open and close under the control of other electrical circuits. While a switch is operated by an electromagnet to open or close one or many sets of contacts, electronic relays are able to control an output circuit of higher power than the input circuit.
