How Do You Read the Caterpillar Engine Fault Codes?

Caterpillar engine fault codes can be read with diagnostic software. This software is available at all reputable mechanics, or it can be purchased for use at home or on the road.

Besides identifying fault codes, the software gives the user the ability to change the Caterpillar engine’s parameters, perform diagnostic tests on the engine, and calibrate sensors and controls. The software can be purchased on its own, or as part of a kit containing a laptop and a diagnostic adapter.

There are several types of Caterpillar engine fault codes. The CID, or component identifier, indicates that there is a problem with a specific component. FMI stands for failure mode identifier, and it shows what kind of failure occurred. The module identifier, or MID, shows which electronic control module has failed. The electronic control module keeps track of what happened during the malfunction, providing a detailed history to help diagnose and fix the problem.

Caterpillar engines have been in production worldwide for over 85 years. They power tractors, industrial machines and boats. Caterpillar engines are responsible for machinery used in forestry, mining, agriculture, oil drilling and well servicing. They are also used in gas compression, construction sites, and power production in businesses, hospitals and ships.
