ECM Symptoms You Should Never Ignore to Ensure Your Semi Truck Engine Functions Effectively

The engine control module (ECM) is a brilliant innovation that has been helping semi truck owners to run their vehicles smoothly and cover long distances. It’s a sophisticated piece of technology that optimizes the performance of your truck.

However, like any other mechanical component, it can malfunction and require repairs, reprogramming, or replacement. Here are three ECM symptoms you should never ignore to ensure your semi truck engine functions effectively:

Semi truck won’t start

If your semi truck doesn’t start, you should start diagnosing the problem. First, check if the vehicle has run out of gas. After that, test the battery by trying to jumpstart the vehicle. If it doesn’t work, check ignition switch by turning on the headlights.

If these problems don’t solve the problem, the chances are that the ECM isn’t working, especially if the vehicle cranks but won’t start. It shows that the engine of your truck isn’t getting the vital inputs from the computer which are important to power your vehicle.

Poor fuel economy

If your semi truck isn’t offering good mileage, it’s also a symptom of a faulty ECM. A malfunctioning ECM is unable to calculate the optimal amount to fuel required to burn in the combustion process, and as a result, lead to poor fuel economy.

As a result, your semi truck consumes more fuel than it needs to function effectively. If you have a commercial transportation business, it can add up to hundreds of dollars each month; hence you must get your ECM repaired or reprogrammed.

Check engine light is on

Check engine light, as the name suggests, shows if there’s a problem in the engine. If it doesn’t go off after your get your truck inspected for potential issues, it’s a clear sign that something’s wrong with the ECM of your vehicle.

Particularly, if you get a particular error code and get it fixed, but the check engine right remains on, then it’s likely that your ECM is to blame. Get the ECM diagnosed from a professional service provider to avoid problems later on.

Final words

If you observe any of these symptoms and suspect that your ECM is malfunctioning, it’s critical to get it checked from an experienced ECM service provider to confirm that if it’s functioning properly.
