EDC Light on Iveco [Meaning, Common Causes & Fix]

One of the most common problems with Iveco’s from my personal experience is the EDC light coming on followed by the vehicle going to limp mode, cutting power, and in some cases falling to start.

In this article, I am going to discuss what an EDC light is, why it comes on, and how you can fix the problem.

What Does the EDC light mean on an Iveco?

In short, EDC stands for Electronic Diesel Control and is a system that helps control the fuel injection and ignition of your Iveco.

The EDC light comes on when there is an issue with one or both of these functions. There are a lot of things that can cause the EDC to light on an Iveco, the most common causes are dirty injectors, bad throttle bodies, or faulty injectors.

What is Electronic Diesel Control?

Electronic Diesel Control (EDC) is an electronic system that controls the fuel injection in diesel engines.

It provides precise metering and delivery of fuel into the combustion chamber for improved engine performance, fuel economy, and lower exhaust emissions.

EDC ensures the engine runs within its limit by using a dynamical range set by the accelerator pedal position.

What Causes Iveco EDC light to come on?

As I mentioned above, there are a number of causes for the EDC light to come on. from my experience, here are the most common causes:

1. Bad Engine Immobilizer:

This is also known as an immobilizer or a security system. It keeps your Iveco from being stolen by disabling the engine when someone tries to start it without the right key.

If the Immobilizer is faulty it won’t be able to tell the difference between the right key and a wrong key, as a result, your Iveco may think your key is the wrong one and put your vehicle into limp mode and check EDC light on.

2. Bad Fuel Rail Pressure Sensor:

These sensors are prone to fail on Ivecos, A fuel rail pressure sensor monitors the pressure of the fuel inside the fuel rail.

This sensor is typically cylindrical and located on the fuel rail. It features a sensitive element that is coupled with an integrated electronic circuit.

The sensor is used by the ECM (Engine Control Module) to ensure that the engine cylinders receive the correct amount of fuel at the right pressure.

A bad Fuel rail sensor will give your Iveco inaccurate fuel pressure readings, as a result, the EDC light will come on. I recommend you start by checking this sensor.

3. Dirty Diesel Fuel Injectors:

Over time, the Fuel injectors in your Iveco can get clogged up with deposits and dirt. This is because Diesel fuel is a highly lubricant, so it attracts dirt like debris.

The problem isn’t just that the injectors are dirty; they also begin to stick in their seats, which means they don’t open fully when the ECM tells them to spray fuel into the engine cylinder.

4. Faulty EGR Valve:

Another common cause is a faulty EGR (exhaust gas recirculation) Valve. The EGR valve is an emission control device used in both gasoline and diesel engines.

It works by connecting the exhaust manifold to the intake manifold and allowing a small amount of exhaust gas to be recirculated back into the combustion chamber.

This helps to maintain the combustion chamber temperature and reduce nitrogen oxide emissions. The EGR system is usually controlled by either a vacuum or an electric step motor.

While it helps reduce emissions, a faulty EGR valve can cause engine performance issues such as poor fuel economy and decreased power output, as a result, the EDC light will come on if the EGR Valve is bad.

5. Failing Throttle Body:

A faulty throttle body can cause a whole host of problems including the EDC light coming on. The throttle body is the part of your Iveco’s engine that controls how much air goes into the combustion chamber, so if it’s not working correctly then you may experience poor acceleration and difficulty driving at high speeds.

The throttle body is controlled by a butterfly valve that opens and closes according to fuel demand.

How to Reset the EDC Light on an Iveco?

As an Auto technician, I recommend that you get the vehicle scanned for fault codes using a proper OBD scanner.

Since the EDC light on your Iveco can be caused by the things I mentioned above, there are other rare causes for this problem.

I recommend that you have the vehicle scanned for fault codes and see what comes up. If it’s an issue with the Immobilizer then replacing it is your best option.

    1. My truck displays EDC on the dashboard, and it sometime hard to start, and doesn’t raise power and the sound is not normal

  1. I have the EDC light on when going up hills or acceleration, also have particulate filter come on when under pressure????it’s a 2017 Eurocargo

  2. Good evening all my Iveco Daily put the EDC light on this evening its due an oil change tomorrow would a bad oil cause the light to come on as there seems to be no loss of power and when i let the engine cool and restarted the light was out.Any thought would be useful .

  3. Hi, I recently urchased Iveco daily high matic 2019

    First long distance job I did EDC & big loss of power

    After it had been parked up for 2 hours waiting for AA who didn’t help at all as once started up no edc & was back driving normal

    2nd job next day 3 hours in & id had to slow to 50mph accelerated quite hard to go back up to 70mph quickly & this time orange engine symbol check engine notification & EDC limp mode

    I had recovery to my local Iveco, they had it 2 weeks & say they couldn’t find a fault suggested I had full service this all cost me 1,900.00
    Shocking cost

    Did a couple of 200 mile jobs it’s been fine

    Just now while on way to job similar thing had to slow right down to 40mph again
    accelerated hard to get back up to speed & CHECK ENGINE NOTIFICATION CAME ON (no engine symbol) & limp mode

    I literally don’t know what to do I need to work & I can’t & I can’t afford another 2 grand bill

    Iveco said it hadn’t had much tlc in its life, unfortunately they didn’t say how dirty engine filter was or anything

    I do have read out from RAC & Iveco who says they couldn’t read RAC codes

    There was also another problem not sure if related or not but they also couldn’t fault gear lever but it was not going into park they put a donor one in & tested etc put mine back in & said no faults were found & that has been working fine so far but I’m not holding hope for that issue staying resolved now after what’s just happened

    Any help would be much appreciated

  4. Hi, I’ve an iveco lorry 2005, 180E, EDC light comes on when driving, new fuel filters, had computer put on it and it said fuel pressure sensor, got that changed and still doing the same! Any suggestions? Nearly 170000 kms on the clock (genuine)
