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 SL600 V12-6.0L - Loud screeching noise when I start the car - Goodyear, Arizona

I have an older Mercedes 600SL and was somewhat concerned about using some one other than a dealer, but my fears were put to rest after my initial conversation with Steve. Steve was on time, knowledgeable, had all of the required tools. diagnose the problem and gave me a stalemate of cost for the repair. He did not try to over sale me on something I didn't need. He made the repairs made sure that everything was correct and assured me that if I needed anything more he was just a phone call awaly. Steve called me the next day just to check that the repair was good.

Mercedes-Benz SL600 V12-5.5L Turbo - Brake Pads Replacement (Front) - Huntington Beach, California

Highly recommend Chris and will request him next time I need service on my Mercedes SL600 V12 Turbo Roadster! Chris is an expert craftsman who really knows about my Mercedes. I was happy about saving money by not going to the dealer for service. Who knew you can have your car serviced at home while getting things done around the house instead of wasting time driving to a dealer and hanging out in their waiting area! I will definitely request Chris next time my car needs service!!
