This information can be helpful for troubleshooting
intermittent problems. Logged codes can also be
used to review the performance of the engine.
Clearing Event Codes
A code is cleared from memory when one of the
following conditions occur:
• The code does not recur for 100 hours.
• A new code is logged and there are already ten
codes in memory. In this case, the oldest code is
cleared.
• The service technician manually clears the code.
Always clear logged event codes after investigating
and correcting the problem which generated the
code.
Troubleshooting
For the basic troubleshooting of the engine, perform
the following steps to diagnose a malfunction:
1. Obtain the following information about the
complaint:
• The event and the time of the event
• Determine the conditions for the event. The
conditions will include the engine rpm and the
load.
• Determine if there are any systems that were
installed by the dealer or by the customer that
could cause the event.
• Determine whether any additional events
occurred.
2. Verify that the complaint is not due to normal
engine operation. Verify that the complaint is not
due to error of the operator.
3. Narrow the probable cause. Consider the operator
information, the conditions of operation, and the
history of the engine.
4. Perform a visual inspection. Inspect the following
items:
• Fuel supply
• Oil level
• Oil supply
• Wiring
• Connectors
Be sure to check the connectors. This step is
important for problems that are intermittent. Refer to
Troubleshooting, “Electrical Connectors - Inspect”.
If these steps do not resolve the problem, refer to
Table 11 or Table 10 for the procedure to troubleshoot
the event code.
