Use the following procedure when a diagnostic code is detected. When a diagnostic code is detected, the Display Area shows the "SERV CODE" indicator while the Main Display Module is in Normal Mode.
Enter Service Mode (Mode 2).
A single diagnostic code is shown and the code is on hold at this time. The display toggles between the MID and the CID FMI. When the diagnostic code is not active, nothing is shown for the MID. The Display Area does not toggle showing information on the diagnostic codes.
In order to see all of the detected diagnostic codes, use the "SCROLL" switch to scroll through the diagnostic codes. The Display Area momentarily shows the MID. Then, the Display Area shows the CID FMI in place of the MID. Toggle the "SCROLL" switch in order to see each diagnostic code in succession. The MID shows "End" after the last diagnostic code has been shown.
Place the desired diagnostic code on hold by releasing the "SCROLL" switch.
Make sure that the MID "030" is displayed.
Observe the "SERV CODE" indicator.
If the "SERV CODE" indicator is ON, then the diagnostic code that is shown is active.
If the SERV CODE indicator is OFF, then the diagnostic code that is shown is logged. The diagnostic code was active. Then, the diagnostic code became inactive. The diagnostic code was logged in memory. This may or may not indicate an intermittent condition.
In order to troubleshoot the diagnostic code, go to the procedure with the CID FMI.
After a diagnostic code is corrected or the diagnostic code is not needed, clear the diagnostic code by using the "CLEAR" switch. After clearing the diagnostic code, the Display Area advances to the next available diagnostic code.
Repeat Step 2 through Step 8 for the remaining diagnostic codes. The operator should return to Normal Mode when the operator is finished.Troubleshooting Procedures
Go to the procedure which corresponds to the CID FMI that is shown in the Display Area.Note: The procedures for the CID FMI that are found in Testing And Adjusting may cause some diagnostic codes to be logged by the Main Display Module. Therefore before performing any procedures, record the diagnostic codes in order to determine the problems that are in the system. At the completion of each procedure, clear the diagnostic codes that were caused by the test procedure.
