The following list contains some of the functions of the display module:
- The diagnostic codes of the ECM systems are displayed.
- The settings for the ECM are displayed.
- The machine status parameters are shown in real time.
- The number of occurrences and the clock hour of the first and last occurrence are displayed for each of the events, active codes, and logged codes.
- The definition for each logged diagnostic code and each event is displayed.
Note: Refer to "Service Menu" for more information.
The diagnostic codes can be viewed with the Display Module or Cat® Electronic Technician (Cat ET) Service Tool.
The following procedures may cause new diagnostic codes to be logged. Therefore, before any procedures are performed, make a list of all the active diagnostic codes to determine the system problems. When each procedure is complete, clear the diagnostic codes that were caused by the procedure.
Note: Before performing a procedure, always check all the circuit breakers. Repair the cause of any circuit breaker that has tripped.
An Event indicates a reading that is outside of normal operating ranges but within component limits. An example might be a high oil temperature reading. The event will be identified by the ECM, the EID, and a time stamp.
The Component Identifier is a four-digit number that represents a particular component on the machine. For example, each solenoid that is connected to the Machine ECM has an assigned number.
The codes for the Failure Mode Identifier are defined by SAE standards. The following list contains a AVSpare version of definitions.
| Failure Mode Identifier | |
|---|---|
| FMI | Description of Failure |
| 00 | Data valid but above normal operating range |
| 01 | Data valid but below normal operating range |
| 02 | Data erratic, intermittent, or incorrect |
| 03 | Voltage above normal or shorted high |
| 04 | Voltage below normal or shorted low |
| 05 | Current below normal or open circuit |
| 06 | Current above normal or grounded circuit |
| 07 | Mechanical system not responding properly |
| 08 | Abnormal frequency, pulse, or period |
| 09 | Abnormal update |
| 10 | Abnormal rate of change |
| 11 | Failure mode not identifiable |
| 12 | Bad device or component |
| 13 | Out of calibration |
| 14 | Not used |
| 15 | Not used |
| 16 | Parameter not available |
| 17 | Module not responding |

Subpage (1) Information Message Banner | |
An Information Message Banner (1) is used to inform the operator on various incidents that do not have a warning or a fault code.
In Illustration 6, the Information Message Banner (1) is informing the Master Operator that the addition of another operator has been added successfully. A similar message would appear to inform the operator that the procedure was not successful.
This banner will be visible for 3 seconds.
