(1) | This table pertains only to diagnostic codes with a MID of 081. |
The "Advisor" displays maintenance events that originate from electronic controls. The events are shown on the message area. Other electronic control modules transfer this diagnostic information through the Cat Data Link to the "Advisor" module.
The electronic control module that has detected a failure is identified by the Module Identifier (MID). Each electronic control module on the machine has a unique MID. Use table 2 to match the MID for each failure to an electronic control module. Refer to the "Module Identifier table" on the machine Electrical System Schematic if the MID that is shown does not appear in table 2. After the electronic control module that detected the failure has been identified, refer to the failed controls Service Manual for troubleshooting information ("CID/FMI"). The Service Manual modules for each control are part of the machine Service Manual.
If the MID is for a "Advisor" module, use the Service Manual, KENR9022 module to troubleshoot the failure. This Service Manual, KENR8393 module contains troubleshooting procedures for the Power Train only. Refer to the Troubleshooting section of this manual for the individual diagnostic code procedures.
Note: Maintenance events that originate in other electronic controls may be automatically cleared from the control when the event is transferred to VIMS. The data events are not affected.

The Component Identifier (CID) is a code that describes the component that may have a failure. The "MID/CID/FMI" can be used to see the whole story.
Each Failure Mode Identifier (FMI) is defined by SAE standards. The Caterpillar definitions that are listed here are applied to Caterpillar products. The relationship between sensors and FMI codes is shown in Illustration 1. The types of sensors are listed here: frequency sensors, analog sensors, and digital sensors.
