Modules

Engine and Transmission Control Modules

Control modules throughout your vehicle are responsible for a variety of functions, including engine performance and efficiency, transmission and drivetrain operation, braking, climate control, and more. The most common control modules on modern vehicles are engine control modules (ECMs) and powertrain control modules (PCMs), which use input from a variety of sensors to adjust the way the vehicle runs and drives. This helps to maximize efficiency and ensure that the vehicle operates at its best. When engine and powertrain control modules begin to fail, you may experience erratic shifting, misfires, rough idle, or other performance issues, and it may require extensive diagnosis to determine whether one or more sensors or the control modules themselves are to blame. O'Reilly Auto Parts carries replacement engine and powertrain control modules, accelerator control modules, and the sensors and parts you might need to keep your vehicle operating at its best.

Brake Control Modules

Another area of your vehicle that requires a working control module is the anti-lock braking system, or ABS. ABS uses input from wheel speed sensors to detect traction loss during braking, and is designed to pulse the brakes appropriately to prevent skidding and minimize braking distance. A failing ABS control module will likely cause poor braking in wet or slippery conditions, and the ABS warning light may turn on to alert you to a problem. Other brake control modules, including the parking brake module, allow you to use additional brake functions to set the parking brake and prevent your vehicle from moving. No matter what type of brake control module you need, shop O'Reilly Auto Parts before you make your repair.

Body and Climate Control Modules

In addition to the performance and safety systems on your vehicle, the various amenities on your vehicle may also use dedicated control modules to keep them working as they should. This can include climate control modules for your heating and A/C system, headlight control modules, airbag control modules, cruise control modules, and more. These components control all of these safety and convenience systems to keep you driving comfortably. When any of these body control modules fail, they can cause significant effects to their respective systems. If you've noticed any issues with your accessory systems, it may be necessary to trace the issue and determine if the module may have failed. If you need to replace any of your body control modules, engine and drivetrain control modules, or brake control modules, O'Reilly Auto Parts has a complete selection of vehicle electronics repair parts to help keep your vehicle driving at its best.
