4 Types of Vehicle Control Modules

Technological advancements have made computers an essential part of modern life. They power our phones, help us work remotely, and have even begun taking tourists into space! There are also special computers in our vehicles that optimize our driving experience. These are known as control modules and coordinate everything from our vehicles’ braking systems to gears.

Here’s a summary of the four most common vehicle control modules.

1. Engine Control Module

Wondering how your vehicle’s onboard computer can save you money? The answer is the engine control module (ECM)! ECMs are responsible for controlling the fuel efficiency, carbon emissions, and engine performance of a vehicle. Therefore, it’s possible to regulate how much air and fuel is used by your engine through ECM programming.

ECM module problems can cause your vehicle to underperform and use fuel inefficiently. If you feel your fuel bill is too high, then it’s vital to get ECM experts to check whether you need your ECM repaired or replaced.

2. Transmission Control Module

Transmission control modules (TCMs) were first introduced in the 1980s and are used to electronically control gear changes in vehicles. They work in tandem with ECMs to ensure a vehicle can accelerate as quickly and efficiently as possible. If your vehicle isn’t able to shift gears properly, then you must get your TCM checked by professionals.

3. Suspension Control Module

If you’ve ever driven over a pothole without feeling a thing, then you have your vehicle’s suspension control module (SCM) to thank! SCMs control various aspects of your vehicle’s suspension, such as ride height and spring pressure. They can be adjusted to ensure you travel smoothly both on and off-road.

4. Brake Control Module

Did you know computers in your vehicle help you brake optimally? These are known as brake control modules (BCMs) and mainly consist of anti-lock braking systems (ABS) and traction control systems (TCS). ABS prevents vehicles from skidding while braking. On the other hand, TCS uses electrical signals to prevent vehicles from sliding when they turn.

Engine control modules are the most important of all vehicle modules. If you’re looking for an expert in ECM repair and reprogramming, then come see us at CATECM. We have an array of Caterpillar ECMs for sale and are ready to talk to you 24/7 about truck ECM replacements.
