Our Services

CATA Electronics specializes in the diagnosis, remanufacturing, and programming of diesel engine control modules for Caterpillar, Cummins, and Detroit truck engines. Our testing machinery are equipped with technology to read Diagnostic Trouble Codes (DTCs) and test operational functionality of various engine components such as injectors, fuel pumps, sensors, and more. Due to our large inventory of units, we can offer delivery in as little as the next business day! We also offer professional programming and reflashing services for features, parameters, and engine power rerates.

All of our remanufactured ECMs come with an unlimited 1-year warranty.


Our proprietary testing equipment was developed and designed for a variety of Caterpilar, Cummins, and Detroit Diesel engine models. Our diagnostics process consists of the following procedures:

  • Evaluating Diagnostic Trouble Codes (DTCs)
  • Testing electrical functionality of injectors, fuel pumps, sensors, and other components.
  • Visually inspecting circuit boards for water damage or burns.


We fully understand how precious time is in the logistics industry which is why stock more ready to ship ECMs than anyone else. If your module is determined to be faulty we offer same day shipping on exchange units if ordered before 3 PM (CST). All of our exchange units have been fully tested and are ready to be programmed to your engine and truck specifications.

Non-Rebuildable Cores

Unfortunately, not all ECMs can be rebuilt due to a number of circumstances that can result in water damage or circuit board burns. If your module has been deemed as non-rebuildable a core fee will be applied. The core fee amount will depend on the make and model of your engine.


Our professional ECM programming services are readily available whether you need calibrations, feature/parameter changes, or rerating your engine's power. Determinability of engine rerates will depend your engine model specifications. Please contact us for availability on your model.
