As technology continues to evolve and change, the way we operate and operate our vehicles is evolving. It appears that more and more components rely on computers, sensors, and capacitors. Examples of these technological advances are ECM or electronic control modules (engine control modules) or power train control modules. Many factors affect life expectancy.
Build Quality-
As with the vehicle itself, the quality of manufacture of electronic control modules varies greatly, which in turn affects the useful life of the part. Some manufacturers use inferior components and install the circuit board into plastic housings. This is done to save costs and reduce the weight of the module. As a result, the life of the control module may be shortened.
External Factors That Affect the Lifespan-
Placement-
Electronic Control Module when exposed to components in the engine compartment, the module is placed in the vehicle to extend the life of the ECM; extreme heat, corrosive moisture, and moisture can adversely affect the electronic control module. Exposed wires, plugs and adapters also appetize mice and other rodents! Automotive Electronic Control Modules in the trunk are also exposed to overheating, exposing leads, plugs, and adapters several times.
The BCM or Body Control Module (also known as GEM Module (General Electric Module) and Multi-Function Module) are usually located inside the vehicle; they can be under the dashboard, under the seat, or inside the floor. On the surface, all the components are safe except for heat, which is usually made of cheap plastic and is not very durable. However, similar components, the front control module is located in the engine compartment. Compared to other types of modules, low-quality houses and combinations exposed to high temperatures can result in an increase in the number of these types of Automotive Electronic Control Modules that require repair or replacement.
The TCM or transmission control module is almost always exposed, sometimes inside the PCM of the engine compartment or connected to the transmission.
