Mode 0: Service Code Indicator ONService Mode (Mode 2) assists service personnel with the troubleshooting of diagnostic codes. All the recorded diagnostic codes can be cleared from memory while the operator is in Mode 2.Note: Events can not be viewed through the main display module. Events can only be viewed using the CAT ET Service Tool.In order to enter Mode 2, hold down the "CLEAR/MODE" switch until "-2-" appears in the display area. Three identifiers are used to specify each detected diagnostic code. These identifiers are shown on the Display Area. The Display Area alternately shows the Module Identifier (MID). The Component Identifier (CID) and the Failure Mode Identifier (FMI) are then shown on the Display Area. The Display alternates continuously between the MID and the CID FMI. Identifiers include the following items.Module Identifier (MID) - The MID is a three digit code that is shown on the six digit Display Area. The MID is displayed for approximately one second, before the CID FMI is shown in place of the MID. The MID helps the operator to determine the electronic control module that has generated the diagnostic code. Some values that may be seen for the MID are given in the following list.
Main Display Module 030
Primary Engine Control Module 033, 034 or 036
Secondary Engine Control Module 047
De-Nox Control 076
Customer Communication Module 097
Programmable Relay Control Module 099Component Identifier (CID) - The CID is shown on the first four digits or the first three digits of the six digit Display Area. The CID and the FMI are displayed together. The MID is followed by the CID FMI in the Display Area. The CID identifies the component or the subsystem that has generated a diagnostic code. For a listing of the CID codes, see the chart that is attached to the left side of the Electronic Instrument Panel. One example of a detected diagnostic is the "THROTTLE SIGNAL OUTPUT IS ABNORMAL".Note: Earlier models display three digits for the CID. The fourth digit has been added to the CID in order to provide the ability to develop four digit codes.

Failure Mode Identifier (FMI) - The FMI is shown on the last two digits of the six digit Display Area. The FMI begins with the decimal point or an "F". The FMI ends with the two digit code. The CID FMI is displayed immediately after the MID. The diagnostic code that is generated is revealed to the operator through the FMI. A listing of the codes that are used for the FMI may be found on the left side of the Electronic Instrument Panel. The example that follows is for "THROTTLE SIGNAL OUTPUT IS ABNORMAL".Note: "F" is used on the earlier models in order to distinguish between the digits of the CID and the digits of the FMI. The "F" has been removed in order to allow the fourth digit in the CID to be added, and the decimal point is the separation between the CID and the FMI.
