What is the Electronic Control Relay all about?

A wide range of electronic systems must work properly in order for the vehicle to operate. That means there is a need for several different controllers to ensure proper operation. One of the most important is the electronic control relay. You might be more familiar with the term “main relay” because of its role in vehicle performance.

The electronic control relay operates the fuel pump and sends power to the engine’s injectors. Without the main relay, fuel will not flow from the tank to the engine, and your injectors will not atomize gasoline into the combustion chamber. In short, your car wouldn’t run. Electronic control relays are subject to failure from a number of different problems, including outright failure, heat damage, cracked solder and more.

Keep in mind:

  • The electronic control relay may not operate, or may operate intermittently depending on the source of the trouble.
  • A number of other problems can masquerade as a main relay failure, so it’s vital that you have one of our expert mechanics diagnose the issue.

How it's done:

  • The electronic control relay is located and accessed then verified it needs replaced
  • The defective relay is removed from the vehicle
  • The new electronic relay is installed
  • The components that the electronic relay operates are checked for proper operation
  • The vehicle is road tested for proper operation

Our recommendation:

Traditional turnkey ignition the relay will click three times during the starting process. If you listen closely, you should hear a single click when you turn the ignition to “on”. You should hear another when the Check Engine light turns off. Finally, there should be a third click when you turn the key to the “start” position. If you do not hear a click at any of these three points, there may be a problem with the electronic control relay. Have one of our expert mechanics diagnose and replace the relay if required.

What common symptoms indicate you may need to replace the Electronic Control Relay?

  • Engine doesn’t start, especially in cold weather
  • Engine may not start a few minutes after turning it off
  • No sound from the fuel pump when the ignition key is turned to “On”

How important is this service?

Given the fact that the electronic control relay powers the fuel pump and your fuel injectors, it is essential to replace a faulty one. However, many other problems can present similar symptoms, so it’s very important to have the issue diagnosed by one of our expert mechanics.

Mercedes-Benz GLC63 AMG V8-4.0L Turbo - Pre-purchase Car Inspection - Sugar Land, Texas
David was selected by Your Mechanic to conduct a re-inspection after the initial inspection failed to disclose obvious cosmetic defects. David was thorough in both his inspection of the areas under concern, as well as re-inspecting the entire vehicle's condition in the event the first inspection failed to reveal less obvious defects. David confirmed the suspect cosmetic defects and I'm now working with Your Mechanic to resolve the disparity from the initial PPI conducted which should have disclosed such defects. As to David, he provided a thorough inspection, commentary via voice memos, and appropriate media for me to fully grasp the nature of the car - what should have occurred the first go around. I appreciate his professionalism and I look forward to resolving the disparity with Your Mechanic's customer response team. Things don't always go to plan, the true measure of a company's worth, credibility, and trust, is how they respond to customer's when things deviate from plan. I'm hopeful that Your Mechanic's leadership team will persevere and remedy this situation in a timely fashion. Thank you.
