When the ECM detects a fault, the corresponding CID and FMI are shown on readout (1) of the display. Service mode (mode 1) allows for troubleshooting and clearing of each detected fault. For detailed information, see Systems Operation, "Diagnostic Operation". Use the following procedure for troubleshooting a detected fault. When a fault is detected, the readout will show the fault.
Enter service mode (mode 1).
The CID and FMI for the first fault are shown on readout (1) and the fault is on-hold at this time. The display shows "---" when no fault has occurred.
To see all detected faults, scroll the faults. To do so, move the "Increment/Clear/Store" switch to the Increment position.
Place the desired fault on-hold (stop the scrolling). To do so, release the Increment/Clear/Store switch when the desired fault is shown.
Observe fault present indicator (2). If the fault present indicator (2) is ON, the fault shown is currently present. If fault present indicator (2) is OFF, the fault shown is not present at this time. The fault has occurred and then went away, sometime in the past (intermittent).
To troubleshoot the fault, go to the procedure with that CID and FMI. Note: A general method to locate intermittent fault is to wiggle the related wiring while a helper watches the status of the fault present indicator (2) .
After a fault is corrected, clear the fault. To do so, press the Increment/Clear/Store switch to the Clear/Store position. After clearing, the display advances to the next fault if there is one.
Repeat Steps 2 through 7 for any remaining fault. Return to normal mode when finished. The CID FMI troubleshooting procedures are only for service codes originating from the 350 Machine Control ECM. Go to the procedure which corresponds to the CID and FMI which is being shown on the display. The CID FMI procedures may cause new faults to be logged. Therefore, before performing any procedures, make a list of all service codes to determine system problems. At the completion of each procedure, clear the faults that were caused by the procedure.
