Closing codes
The system contains four types of closing codes: action codes, cause codes, failure
codes, and problem codes.
Action codes describe the steps necessary to correct the problem, such as adding lubricant to a pump. Cause codes identify what caused the component or type of component to fail. Failure codes identify the reason the equipment failed. Finally, problem codes identify the observed equipment failure, such as a leak from a faucet or the overheating of a pump.
