What does engine control relay do?
What does engine control relay do?
The Engine Control Relay function allows the Nexus ECU to control the 12V+ power supply to certain parts of the engine management, such as injectors and ignition coils. This function should remain enabled when a Haltech supplied universal wiring loom with the integral fuse/relay box has been installed in the vehicle.
How does the main relay work in a car?
Main Relay Function Your vehicle’s main relay gives power to your car’s most electric components, like the engine control unit and other control modules. When you turn your vehicle on, it shifts the relay to a new position, which allows you to start your vehicle by sending power to the necessary components.
Why is the electronic control relay so important?
The electronic control relay is particularly important, as it is one of the main relays that feeds power to the computer, which controls a vast majority of the vehicle’s functions. As the electronic control relay powers the computer, when it fails it can cause all sorts…
What happens when the ignition relay goes out?
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
What are the pins on an engine relay?
Pin 85 and 86 are the coil. So we will hook one up to 12v, and one to ground. This way when the relay receives either voltage or is grounded the relay will jump into action. So when it does “jump into action” what will it do? Well in this case it will take whatever voltage is on input 30 and switch it from outputting on pin 87A to pin 87.

How does the EEC power relay work in a car?
The EEC Power Relay not only supplies battery voltage to the fuel injection computer (also known as the E.E.C. Electronic Control Assembly), but also supplies power to the fuel injectors, the fuel pump relay, and a few other emissions related solenoids. The EEC Power Relay is easy to recognize…
