An automotive electronic control module has many of the same features as a computer at your office or home. It has a microprocessor for receiving, interpreting and reacting to sensor inputs and is composed of a standard circuit board hardware encoded with software. The software contains instructions that tell a car how to run. Just a few original equipment manufacturers make ECM systems for cars. Each type and brand needs to be custom made to fit the specifications of the automotive manufacturer specifications. ECMs also need to be configured by manufacturers to perform optimally, taking specifications and other aspects into account. The OEM suppliers offer wide and varied engine computer products with different features and benefits. The system can work with a range of cars, but ECMs vary based on fuel type, engine size and more.

ECM: The Essential Ingredient for Better Rides

Automotive electronic control modules provide fuel and regulate emissions. ECM is responsible for monitoring and regulating the throttle position sensor which tells the engine how much air and fuel to mix to make power. The ECM can malfunction just like any other car part.

The Difference between Replacing and Repairing

Replacing an ECM is not the same as repairing it. Engine control modules do go bad but ECM repair is not a matter of going to an average mechanic. It takes special tools and specific knowledge to repair an ECM. Repairing an ECM requires disassembling the unit and carrying out precise and accurate electronics work. It is much like removing and opening the unit and looking around to see if there is electrical damage. If corrosion from acid or moisture results, it will be easily visible.

When to Replace or Repair

Replacement is also a costly process. Troubleshooting and eliminating problems before pulling out the ECM and installing a new one is important. Replacement can be complicated and costly if the ECM has been modified to accommodate security systems, immobilizers, smart keys or any electronic configured to the car. Many ECM repair services can prevent your automotive electronic control modules from becoming damaged further. Just like a bad ECM can cause electrical problems, the opposite also holds true. Faulty or malfunctioning sensors can damage the ECM. A thorough troubleshooting procedure before understanding the source of the problem is important. Only a skilled professional can help you in this respect.
