They operate independently throughout the unit operations, sharing data in case a certain function expects both systems to work in tandem. It also has a great benefit for tuners, because it means they can program one system and leave another unaffected.
In the automotive electronics industry, Control Unit ECU is used as a generic term for any built-in system that controls multiple electrical features in a car. It usually includes:. Sometimes one assembly consolidates several different systems from this module list. Most modern cars have up to 80 different ECU Units. Your engine control module is not something you should take lightly when it comes to your vehicle, repair or replace it as soon as possible.
PCM stands for powertrain control module. A powertrain control module handles the emissions, transmission and charging systems of your vehicle.
As a powertrain module, it is responsible for overseeing the driveline and engine as well. With the sensors in place and data being transferred, it makes quick adjustments to ensure optimal engine efficiency and performance. Over time, it also learns more about the operations to make it even more efficient. Of course, this list could continue on because the PCM acts as the heart and brain of the modern vehicle.
While these two have a different name, the modules are essentially the same thing. These electronic modules control multiple systems of the vehicle, including the ABS, airbags, cruise control and air conditioning. However, the engine is what the module is mainly responsible for. It optimizes performance and ensures efficiency by controlling the ignition, fuel injection and airflow. With the help of various sensors, the ECM interprets data, determining what systems need to be adjusted.
It chooses what response to follow up with to create optimal running conditions. The manufacturer programs it to work with a specific vehicle, so it cannot be swapped with a different ECU.
The ECM works in conjunction with the air-fuel sensors, MAF sensors, oxygen sensors , crankshaft and camshaft position sensors, coolant temperature sensor, throttle position sensor and the EGR valve sensor to ensure everything is running as it should. At startup, the ECM will go through a complete systems check to guarantee proper performance.
