Function of this part

The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.

Why this part matters

Without a functioning ECM, the engine will not start or will run poorly. A correct, working ECM is essential for performance, diagnostics, emissions control, and protecting the engine from damage.

About the brand

Mack is known for building tough trucks and components for construction, vocational, and highway fleets that need reliable performance day after day.

Fitment & usage

Used OEM parts are a smart choice for controlling repair costs while still using original-equipment components. Always match the OEM part number(s) listed to your existing part, and consult your service manual, dealer, or technician if you are unsure about fitment.

Note: Because this is a used component, normal signs of wear such as scratches, discoloration, or light surface corrosion may be present. Refer to the product photos and information on Second Truck Parts for the best representation of the part you will receive.

Run out of ink quickly
Style: Ink
When you have the Epson work Workforce Pro 3820 it only accepts Epson cartridges none of the cheaper ones Epson cartridges run out of ink really fast I actually had some of the non-epson brand cartridges in there they worked a couple of times but then one day they absolutely refuse to work so they're worthless and then I had to actually buy the Epson brand name

Good value!
Style: Ink
Received in a timely manner. Installed with ease. Only printed a few pages but all is good so far. Price is more than I would like but very competitive and attractive compared to local office supply stores.
