What is the ECM-Power Relay all about?

Vehicle development has evolved over the past several decades to a point where it seems every vehicle function is controlled by a computer, right down to the engine itself. This is actually the case for the engine and its related functions as it is controlled by the engine control module, or ECM. The ECM monitors and adjusts operation and power distribution to the fuel supply and injection systems, engine timing, exhaust gas recirculation, emissions, ignition system, and several other systems. In order to dispense power to operate these other systems, the engine control module requires power itself.

The power distribution center, or fuse block, located under the hood houses most or all of the vehicle’s fuses and relays. It contains a relay for the ECM that is powered up when the ignition key is turned to the on position. This ECM power relay acts as a switch that supplies power to the ECM. When the ignition is turned off, power switches inside the ECM relay and it no longer receives battery power. If the ECM power relay stops switching as it should, you will experience vehicle problems. When the relay is stuck open, no power will be delivered to the engine control module and the vehicle won’t start. If the relay is stuck closed, constant power will be sent to the ECM even with the engine turned off and the battery will drain.

Keep in mind:

  • The battery should be disconnected any time the electrical system is being serviced.
  • There are several problems which can cause your vehicle not to start, with the ECM power relay being one of them. Have the problem diagnosed by one of our expert technicians.

How it's done:

  • The ECM-power relay is verified that it needs to be replaced. The relay is located in the engine main fuse relay control box.

  • The defective ECM-power relay is removed from the control box by pulling it straight up and out of socket.

  • The new ECM-power relay is installed into the socket and the engine scanned for codes.

  • The engine is started and the ECM-power relay is tested for proper operation.

  • The vehicle is road tested for proper operation of the ECM-power relay and is then checked for codes.

Our recommendation:

The ECM power relay should last the lifetime of your vehicle unless there is a power distribution problem or moisture that causes it to fail. If your vehicle won’t start, have one of our expert technicians diagnose the problem and replace the ECM power relay if necessary.

What common symptoms indicate you may need to replace the ECM-Power Relay?

  • Engine will not start when the key is turned.
  • Engine doesn’t turn over when ignition is on.
  • Check Engine light is on.
  • Battery drain which may leave it weak or dead.

How important is this service?

Although it is extremely unlikely the ECM relay will cause your vehicle to stall or create a safety concern, your vehicle may not start or the battery may die while the ignition is off. In either case, you will need to replace the ECM relay.

BMW M6 V10-5.0L - Electric Problems Inspection - Phoenix, Arizona
Benji arrived about 15 minutes early, which was a nice surprise. He asked me to describe the car's issues and it was immediately clear that he was an expert and was very experienced with high-end cars and electrical problems. Even though he quickly diagnosed the crux of the problem(s), he still took the time to check and rule out (or in) other potential sources and related system failures. This type of analysis never seems to occur at dealerships--instead, they jump to a conclusion (usually the most expensive) you are stuck with. The problem isn't solved or fully solved or some new problem crops up, and they explain why you now need to get more things done as well even though they supposedly weren't wrong with what they "fixed" first. Benji's approach was nothing like that. He was straightforward, logical, honest and smart. I also like knowing who is working on my car--which dealerships don't usually do. Instead, they put a "service advisor" buffer (and BS-er) between the car owner and the person actually doing the work--which leads to miscommunication and dissatisfaction. Customers don't need some bogus translator as though the techs can only speak in russian or some obscure language. Benji also showed me some of the read-outs he got as he tested things--which was helpful too. He understood the car's computer system and coding too--which is not simple in an M6. I would trust Benji with anything from a beloved 20yr old family volvo or pick-up truck to a Bugatti.
