5-1.11.1 Engine Operation with Intermittent Diagnostic Codes
If the diagnostic lamp illuminates during normal engine operation and the diagnostic lamp shuts off, an intermittent fault may
have occurred. If a fault has occurred, the fault will be logged into the memory of the Electronic Control Module (ECM).
In most cases, it is not necessary to stop the engine because of an intermittent code. However, the operator should retrieve
the logged fault codes and the operator should reference the appropriate information in order to identify the nature of the
event. The operator should log any observation that could have caused the lamp to light.
Low power
Limits of the engine speed
Excessive smoke, etc.
This information can be useful to help troubleshoot the situation. The information can also be used for future reference. For
more information on diagnostic codes, refer to
Troubleshooting Guide
for this engine.
5-1.11.2 Customer Specifi ed Parameters
Customer specifi ed parameters that will enhance the fuel effi ciency and the operator’s convenience can be programmed
into the Electronic Control Module (ECM). Some parameters may affect engine operation. This may lead to complaints from
the operator about power or about performance. Certain engine parameters may be programmed by the customer by using
Caterpillar electronic service tools in order to infl uence the operation of the engine:
The customer specifi ed parameters can be changed as often as needed. Password protection is provided so that the
customer can change the parameters. The customer can authorize someone else to change the parameters. Ensure that a
record of the parameters is kept in this manual in the “
Customer Specifi ed Parameters
” section. For detailed instructions on
programming the engine for optimum performance and for optimum fuel economy, consult your Caterpillar dealer.

5-1.12.1 Under-the-Hood Inspection
Perform the required daily maintenance and other periodic maintenance before the engine is started. Inspect the engine
compartment. This inspection can help prevent major repairs at a later date. Refer to the
“Walk-Around Inspection”
section in
this manual for more information.
For the maximum service life of the engine, make a thorough inspection before starting the engine. Look for the following
items: oil leaks, coolant leaks, loose bolts, and trash buildup. Remove trash buildup and arrange for repairs, as needed.
Inspect the cooling system hoses for cracks and for loose clamps.
Inspect the alternator and accessory drive belts for cracks, breaks, and other damage.
Inspect the wiring for loose connections and for worn wires or frayed wires.
Check the fuel supply. Drain water from the water separator (if equipped). Open the fuel supply valve.
Do not start the engine or move any of the controls if there is a “DO NOT OPERATE” warning tag or similar warning tag
attached to the start switch or to the controls.
Ensure that the areas around the rotating parts are clear.
All of the guards must be put in place. Check for damaged guards or for missing guards. Repair any damaged guards.
Replace damaged guards and/or missing guards.
Disconnect any battery chargers that are not protected against the high current drain that is created when the electric
starting motor (if equipped) is engaged. Check electrical cables and check the battery for poor connections and for
corrosion.
