3 Signs That Your Car’s ECM System Is Failing

An ECM is the engine control unit of a vehicle. It controls and monitors car functions, from dictating engine functions to troubleshooting electrical problems. Suffice to say, an electric control module works like a vehicle’s brain. It’s an onboard computer unit containing preprogrammed software that dictates all the electric functions, including the engine function and workload.

But sometimes, an ECM system can malfunction and stop working. As a result, your car won’t start. Or even if it starts, it will not be working correctly. However, the good part is that an ECM doesn’t stop functioning without warning signs. It’s designed to be highly efficient in identifying the smallest of trouble in a vehicle’s system and generating a notification.

Here are some signs of a failing ECM system.

Keep an Eye on the Check Engine Light

The Check Engine Light feature is responsible for identifying a possible malfunction. If you see the light on, it indicates a problem that needs to be addressed. A convenient feature about ECM units is that they generate codes for issues that can be translated using a trouble code scanner.

Engine Misfiring

As mentioned above, an ECM determines the function of an engine, so in case of failure, the engine shows clear signs—the engine stalling for instance. This means that the car engine can stop abruptly and won’t accelerate. It can also misfire because the wrong input from a faulty ECM system doesn’t align with the engine function. Therefore, if you notice these signs, seek an ECM repair service.  

Ignition Problems

If you notice that your car is not starting, it is a significant indication of a failing ECM system. When an ECM system fails, there are no instructions for car functions. Hence the vehicle completely shuts off and stops functioning. Most people confuse ECM failure with a low battery, and that’s understandable. You can rule out the latter by injecting fuel and giving it power if it doesn’t respond even after that.

If any of the above signs resonate, then it’s a clear indication of an ECM problem. CATECM provides reliable ECM repair services in Fort Worth, Texas, including ECM replacement and reprogramming.
