Confirming a CAT C15 ACERT Fuel Injector Failure
There are several reasons for fuel injector failure, including an electronic failure caused by a bad solenoid. It could also be a mechanical failure brought on by contamination. Debris, water, air, or other contaminants could have gotten inside. Expanded clearances might also be to blame if you have gone long periods without fuel injector service.
Look back at our list of symptoms, and if you notice any of them, you can refer to these common causes of fuel injector failure to quickly diagnose your problem. Test your fuel injectors, and if tests confirm a failure, you’ll need a new set of Caterpillar C15 ACERT fuel injectors.
What About the Trim Codes for My CAT C15 ACERT?
Trim codes, AKA trim files, are codes your Electronic Control Module (ECM) uses to determine how long an injector will inject fuel. Trim codes keep fuel injection consistent despite differences in machine tolerances, friction, and magnetic forces between injectors. This helps keep your engine at its best performance.

Newly purchased C15 ACERT diesel fuel injectors come with a disc. This disc allows you to download new trim codes for your ECM. The trim codes on CAT 3406E or C15 injectors are completely different, so you can’t use them. If you want your engine to function well, your ECM needs the new codes supplied with the fuel injectors you bought.
