Troubleshooting

2206D-E13TA Industrial Engine

Level 3 – Level 3 requires an immediate safe

shutdown of the engine to avoid damage to the

engine or injury to personnel around the engine. The

problem that caused the event must be corrected

before engine operation can resume.

Active Event Codes

An active event code represents a problem with

engine operation. Correct the problem as soon as

possible.

Active event codes are listed in ascending numerical

order. The code with the lowest number is listed first.

Illustration 21 is an example of the operating range of

a sensor.

Illustration 21

g01365757

Example of the typical operating range of a sensor

(1) This area represents the normal operating range of the engine

parameter.

(2) In these areas, the engine is operating in an unsafe operating

range of the monitored parameter. An event code will be

generated for the monitored parameter. The sensor circuit

does not have an electronic problem.

(3) In these areas, the signal from the sensor is outside of the

operating range of the sensor. The sensor circuit has an

electronic problem. A diagnostic code will be generated for the

sensor circuit. Refer to Troubleshooting, “Diagnostic Trouble

Codes” for additional information on diagnostic codes.

Logged Event Codes

When the Electronic Control Module (ECM)

generates an event code, the ECM logs the code in

permanent memory. The ECM has an internal

diagnostic clock. The ECM will record the following

information when an event code is generated:

•   The hour of the first occurrence of the code

•   The hour of the last occurrence of the code

•   The number of occurrences of the code

Logged events are listed in chronological order. The

most recent event code is listed first.

Event Codes

This information can be helpful for troubleshooting

intermittent problems. Logged codes can also be

used to review the performance of the engine.

Be sure to check the connectors. This step is

important for problems that are intermittent. Refer to

Troubleshooting, “Electrical Connectors - Inspect”.

Clearing Event Codes

If these steps do not resolve the problem, refer to

Table 10 or Table 9 for the procedure to troubleshoot

the event code.

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

Use the following guidelines as you troubleshoot an

engine symptom:

Gather Information

Download the “Warranty Report” from the engine

ECM before performing any troubleshooting or

clearing diagnostic trouble codes.

Interview the operator about the problem before you

begin troubleshooting, when possible.

•   Air Inlet and Exhaust System

•   Fuel System

Diagnostic Codes

Check for any logged diagnostic codes.

•   Determine if the logged diagnostic codes correlate

to probable causes.

•   Engine Load

•   Determine if the logged diagnostic codes occur at

the same time as the symptoms.

•   Valve Lash

Recommended Actions

probability. Complete the procedures in order.

Note: If the problem only occurs under certain

conditions, test the engine under those conditions.

Examples of certain conditions are high engine

speed, full load, and engine operating temperature.

Troubleshooting the symptoms under other

conditions can give misleading results.

Connectors and Wiring

Check the wiring and the connectors for the following

problems:

•   Damage

•   Abrasion

•   Corrosion

•   Incorrect attachment

Repair: Remove the injector sleeve that is leaking. Carefully

inspect the sleeve for damage. If there are visible signs of

damage to the injector sleeve, replace the sleeve. Replace the

O-ring seals for the injector sleeve and reinstall the sleeve. Re-

place any damaged components.

B. Remove the fuel injectors from the cylinder head.

Refer to the Disassembly and Assembly manual for details.

Do not allow the pressure on the cooling system to exceed

103 kPa (15 psi) during the test. Damage to the cooling

system may result from applying excessive pressure.

Coolant may also be contaminating the fuel system. After the

engine is shut down, the retention of pressure in the cooling

system may cause the transfer of coolant into the fuel system.

Visually inspect the fuel tank for coolant. The contamination of

coolant in the fuel system may damage injectors and other fuel

system components. Ensure that all of the fuel system compo-

nents are in good repair prior to returning the engine to

service.

C. Pressurize the cooling system in order to identify the injector

sleeve that is leaking. Closely inspect the sealing joint around

the top of the injector sleeve. Small amounts of coolant will be

dripping from the injector sleeve that is leaking.

Coolant may also be contaminating the fuel system. After the

engine is shut down, the retention of pressure in the cooling

system may cause the transfer of coolant into the fuel system.

Visually inspect the fuel tank for coolant. The contamination of

coolant in the fuel system may damage injectors and other fuel

system components. Ensure that all of the fuel system compo-

2. Contaminated Engine Oil

Contamination

Result: The oil is contaminated.

A. Check the engine oil for contamination.

B. Check the oil filter bypass valve.

Repair: Determine the reason for any contamination of

the engine oil and make the necessary repairs. Drain the

crankcase and refill the crankcase with clean engine oil.

Install new engine oil filters. Refer to the engines Opera-

tion and Maintenance Manual.

If the oil filter bypass valve is open, the oil will not be filtered.

Check the oil filter bypass valve for a weak spring or for a broken

spring. If the spring is broken, replace the spring. Verify that the oil

bypass valve is operating correctly. Refer to the Disassembly and

Assembly manual.

Result: The oil is not contaminated.

Proceed to Test Step 3.

3. Low Oil Pressure

Restriction

Result: The inlet tube has a restriction.

Repair: Clear the obstruction. Verify the repair.

Result: The inlet tube does not have a restriction.

Proceed to Test Step 4.

A. Engine oil that is contaminated with another liquid can cause

low engine oil pressure. High engine oil level can be an indication

of contamination. Obtain an analysis of the engine oil.

B. The inlet screen of the suction tube for the engine oil pump can

have a restriction. This restriction will cause cavitation and a loss

of engine oil pressure. Check the inlet screen on the suction tube

and remove any material that may be restricting engine oil flow.

When some components of the engine show wear in a short time,

the cause can be a restriction in a passage for engine oil. An indi-

cator for the engine oil pressure may indicate sufficient pressure,

but a component is worn due to a lack of lubrication. In such a

case, look at the passage for the engine oil supply to the compo-

nent. Refer to Systems Operation/Testing and Adjusting, “Lubrica-
