Modern vehicles are heavily tied into computer systems that connect the many components that make things run smoothly. The need for module programming services is now more relevant in the aftermarket than it ever has been, but there are still many auto repair shops that do not perform this service. Bradley’s Auto Service in Red Bank, NJ provides module programming for a handful of brands including Audi, Volkswagen, and BMW.
What is Module Programming (ECM Flashing)?
Module programming, also known as module flashing, module reflashing, ECM flashing, and ECM reflashing, is a tuning technique for your vehicle’s computer. Reflashing an engine computer is the process of replacing the existing software in a vehicle controller with new software. Just like with a personal computer, sometimes it is necessary to perform a software update to fix issues and provide new functions. This is a service that allows the engine to be tuned in the same way that the factory calibration engineers perform the task. Module programming can fix issues but can also be done to help with fuel economy and performance. Companies with fleets of vehicles often hire technicians to perform module programming to save money on gas over time.
What is an ECM?
ECM refers to the engine control module which is one of the primary computer systems found in almost all vehicles. Sometimes the programming in this system can be out of date, and new software needs to be applied. Reprogramming the module can also eliminate false “check engine” lights or other maintenance indicators. A faulty engine control module can also cause issues with the engine and transmission that have nothing to do with mechanical problems.
When Is Module Programming Necessary?
These days there are many more instances where programming is necessary when a component in your vehicle is replaced. Many modern vehicles require programming even after traditionally normal service repairs, such as a battery replacement.
Programming a module is necessary when the module has been replaced. First of all, a module typically is built to fit many different applications and the variations between vehicle models and options usually use different software programs to function properly. This is why certain auto shops will typically provide module programming services for a few vehicle brands because the tools required to perform the software changes are different depending on the vehicle’s make and model.
Reprogramming modules is usually performed in order to correct emission issues or resolve issues affecting the operation of a specific system. Usually, vehicle manufacturers will put out bulletins that indicate what updates are needed.
How Can You Tell If Your Vehicle’s ECM is Bad?
The ECM is one of the most important systems in your vehicle, and it can cause all sorts of problems with the vehicle, and in some cases even render it undrivable if the ECM is not functioning properly. A failing ECM may produce any of the following symptoms to alert the driver of a potential problem.
- Check engine light turns on
- Stalling or misfiring engine
- Engine performance problems
- Car won’t start
- Poor fuel economy
All of these symptoms can be caused by problems outside the ECM, but because the computer is connected to many of the vehicle’s functions, it is generally worth considering that the problem could originate from there.
Should Your ECM Be Repaired or Replaced?
Whenever an ECM is programmed or reprogrammed, it is necessary to diagnose the system completely and properly. In cases where the module needs to be replaced, it is necessary to determine why the module failed. Was it simply a faulty module, or was there a short in the wiring or some other component that damaged the module?
In many cases, the problem with your ECM is on a software level, which means that the software simply needs to be updated. There are no parts that need to be replaced and nothing that physically needs to be repaired. In a case where an ECM needs to be physically repaired, it is often better to simply replace the module altogether. Engine control modules are not designed to be worked on by the average vehicle owner, so having an experienced technician take a look is always a good idea.
