CAT Fault Codes | Caterpillar Engine Errors And Trouble Codes

Cat Diagnostic codes are used by the electronic system in order to alert the operator that a problem exists. A diagnostic code also indicates the nature of the problem for you, and you can see what is the code meaning with our service.

Cat DTC :

Cat diagnostic code information that follows is utilized by Caterpillar machines that are equipped with Caterpillar electronic controls.Component identifiers, failure mode identifiers, and module identifiers are pieces of information that assist service personnel in diagnosing system problems of the machine.

CAT Engine

A component identifier (CID) is a diagnostic code that informs the service personnel of the specific circuit or system within which a problem was detected.CAT CID Code List

A failure mode identifier (FMI) is a diagnostic code that informs the service personnel of the type of problem that has been detected within a circuit or system.CAT FMI Code List

A module identifier (MID) is a diagnostic code that identifies the electronic control module that has diagnosed a fault.CAT MID Code List

How to check CAT machine&engine code ?

In most cases it is not necessary to stop the engine because of an intermittent code. However, we recommend that the operator retrieve the code(s) and refer to the chart in order to identify the nature of the event. The operator should note or document the circumstances (low power, vehicle/engine speed limits, excessive smoke, etc) involved during the time the lamp was ON. Documentation may be useful for future reference, and in order to help troubleshoot the situation.

The YELLOW lamp will flash to indicate a two digit flash code and the SET/RESUME switch may be released. The sequence of flashes represents the system diagnostic message. Count the first sequence of flashes in order to determine the first digit of the diagnostic code. After a two second pause, the second sequence of flashes will identify the second digit of the diagnostic code.

NOTE:We indicate the potential effect on engine performance with ACTIVE fault codes.
