Test Operation

Engine Exhaust Manifold Bank #1 Flow Balance Valve Solenoid Override

This override will energize the exhaust balance valve solenoid to on or off. This override will be used when
troubleshooting the exhaust balance valve.

Aftertreatment #1 Fuel Injector Heater Override

This override activates the output for the heated nozzle in order to clean the nozzle. The output remains
activated for approximately 1 hour. The engine coolant temperature must be greater than 60° C (140° F).
The heat cycle will wait for an active regeneration to complete before starting. Once the override has been
activated, the heat cycle will automatically start as soon as conditions have been met and cannot be
deactivated. It could take up to 8 minutes for conditions to be met for the heat cycle to turn on after being
activated by the override. The heat cycle stops if the engine is stopped. The heat cycle continues when the
engine is started. Active regenerations will not occur until the heat cycle is complete. This override will be
used if a system malfunction was not allowing current to flow to ARD nozzle heater. Lack of current flow
could be caused by a blown fuse, broken heater wire, and other damaged components.

Diagnostic Tests
Cat ET diagnostic tests are listed below.

ARD Fuel Line Purge Test

This is a diagnostic test to initiate an ARD fuel system air purge sequence to remove any air trapped in the
system after assembly or repair/service in the field that can introduce air into the system.

The test allows a quantity of fuel to flow through the ARD fuel supply lines by enabling the electric
priming/ARD fuel pump, and activating the pilot and main fuel valves until it senses that there is consistent
and adequate fuel pressure on the main and pilot fuel control pressure signals.

Injector Solenoid Test

Purpose

The purpose of the injector solenoid test is to diagnose injector wiring and injector solenoid functionality.

Cat ET Location

1. Connect to Cat ET.

2. Select the Diagnostics tab.

3. Select the Diagnostic Tests tab.

https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisweb/sisweb/... 8/22/2017
D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 11 of 57

Illustration 7 g03146818

4. Select the Injector Solenoid Test tab.

Test Operation

This test identifies an open circuit or a short circuit in the circuit for the injector solenoids. The test
activates the injector solenoids one at a time while the engine is not running. A good solenoid will create an
audible click when the solenoid is activated. Cat ET indicates the status of the solenoid as "OK", "Open", or
"Short".

Cylinder Cutout Test

Purpose

The cylinder cutout test allows one cylinder or multiple cylinders to be cut out. The cylinder cutout test is
useful when troubleshooting poor engine performance or a suspected injector failure

Cat ET Location

1. Connect to Cat ET.

2. Select the Diagnostics tab.

3. Select the Diagnostic Tests tab.

4. Select the Cylinder Cutout Test tab.

Test Operation

https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisweb/sisweb/... 8/22/2017
D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 12 of 57

The cylinder cutout test disables the injector by not providing the injector pulse to the solenoid. The
cylinder cutout test can be performed on one injector or multiple injectors at once.

Wiggle Test
Purpose

The purpose of the Wiggle Test is to detect intermittent electrical faults in electronic control systems. The
Wiggle Test function allows the user to determine if there is an intermittent wiring problem. The test will
indicate (by changing the value reading) which parameter moved beyond a predetermined range while
wiggling the wiring harness, sensor, or connector.

Cat ET Location

1. Connect to Cat ET.

2. Select the Diagnostics tab.

3. Select the Diagnostic Tests tab.

D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 13 of 57

4. Select the Wiggle Test tab.

Test Operation

This test requires that the engine is OFF and the key switch is in the ON position (or ECM energized and 0
engine speed). If the engine is started with the wiggle test active, the wiggle test will abort.

The Wiggle Test will reduce all ECM requirements to trip fault codes, making the diagnostics sensitive.
Under normal operation some fault codes need multiple occurrences before the code will log. But during
this test the fault codes will trip the first time.

The mechanic wiggles and shakes the wiring to see if codes go active. An audible alarm is also activated if
the ECM sees any parameter change state electrically. Once the test has ended, the ECM returns to normal
diagnostic state.

Fuel Rail Pump Solenoid Test

Purpose

The high-pressure fuel pump contains two assemblies for pressurizing fuel. Each assembly contains a
solenoid. This test checks each solenoid to make sure that the solenoids are working properly.

Cat ET Location

1. Connect to Cat ET.

2. Select the Diagnostics tab.

3. Select the Diagnostic Tests tab.

Illustration 9 g03146848

4. Select the Fuel Rail Pump Solenoid Test tab.

Test Operation

During the Fuel Rail Pump Solenoid Test, the ECM pulses 105-volt to each solenoid. The pulses are sent at
the proper time and for the correct duration for a given engine load and speed. The ECM monitors the
current flow through the circuit for each solenoid. If the current flow is too high or too low, the ECM
activates one of the following diagnostic codes:

• 1779-5 Fuel Rail Pump #1 Output Current Below Normal

• 1779-6 Fuel Rail Pump #1 Output Current Above Normal

• 1780-5 Fuel Rail Pump #2 Output Current Below Normal

• 1780-6 Fuel Rail Pump #2 Output Current Above Normal

Fuel System Verification Test

Purpose

https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisweb/sisweb/... 8/22/2017
D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 15 of 57

The Fuel System Verification Test compensates for wear of the internal components of each injector over a
time. Internal component wear contributes to lower volumes of fuel being delivered into the cylinder.
Injector wear also increases the amount of leakage past each injector back to the fuel tank. This test
evaluates the health of each injector.

Cat ET Location

1. Connect to Cat ET.

2. Select the Diagnostics tab.

3. Select the Diagnostic Tests tab.

Illustration 10 g03146891

4. Select the Fuel System Verification Test tab.

Test Operation

The engine ECM determines whether the injector is delivering the correct volume of fuel into the cylinder.
Also the engine ECM determines if the injector is delivering a low volume of fuel into the cylinder based
on Valve Closing Time. Valve Closing Time is the difference between the time the engine ECM stops

https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisweb/sisweb/... 8/22/2017
D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 16 of 57

sending current to the injector solenoid and the time the valve takes to return to the valve seat. When the
test is performed, Cat ET indicates the status of each injector as "Success" or "Failed".

Note: Perform the Fuel System Verification Test after an injector is replaced. Also perform when a -2 or -7
code is active.

ARD Ignition Test

4. Select the ARD Ignition Test tab.

Test Operation

The technician can initiate an ARD Ignition Test below 80 percent soot level. The test is a shortened
regeneration (approx. 4 minutes). The test checks all the components of ARD system. The ARD ignition
test checks the functionality of the system to verify that ignition has occurred and combustion is
maintained. The ARD Ignition test also actuates the Main Fuel Solenoid (If Equipped).

Fuel System Functional Test

Purpose

The Fuel System Functional Test contains four separate tests that evaluate various aspects of the common
rail fuel system. The test is a self-guided test that will advance to the next test in the series if the current test
passes. If a test in series fails, the test will abort.

Illustration 12 g03147340

4. Select the Fuel System Functional Test tab.

Test Operation

• The Fuel Pump Gear Installation Test evaluates if the high-pressure fuel pump was installed
correctly.

• The Fuel Rail Low Pressure Test checks for leaks at low rail pressure. The test momentarily cuts out
pumping and injection and measures the resulting rail pressure drop. The test then calculates the fuel
quantity leaving the rail and compares to the expected results.

• The Fuel Rail High Pressure Test checks for fuel leaks at high rail pressure. The test momentarily
cuts out pumping and injection and measures the resulting rail pressure drop. The test then calculates
the fuel quantity leaving the rail and compares to the expected results.

• The Fuel Pump Flow Pump Test assesses adequate fuel pump flow. The test measures rail pressure
response during a single pump event while fuel injection is disabled.

Possible Test Results

• Fuel Pump Not Timed Correctly

• Fuel Pump Flow Too Low

4. Select the EGR System Test tab.

Test Operation

The test is conducted with the engine running at a constant speed and load with machine/vehicle speed
zero.

There are two phases to the test:

• EGR Response Test: Known conditions are established for the engine. The EGR valve is commanded
from open to closed. The response is checked for the EGR Delta Pressure Sensor, EGR Absolute
Pressure Sensor, and fuel quantity. Each input has a unique response time, which will be compared to
a threshold. The commanded EGR valve positions are held for a fixed amount of time to allow the
inputs to stabilize. This procedure is repeated several times to increase accuracy and repeatability.

• EGR Valve Sweep: Known conditions will be established for the engine. The EGR valve is swept
from open to closed repeatedly to check for satisfactory response of the EGR flow.

ARD Air System Service Test

Purpose

The purpose of the ARD air system service test is to determine if the ARD air valve is controlling the
airflow as commanded by the controller. This test will determine if the ARD air valve is functioning
properly.

D6T TRACK-TYPE TRACTOR XL, XW, LGP, Differential Steering GMK00001-UP ... Page 23 of 57

4. Select the ARD Nozzle Heater Circuit Test tab.

Test Operation

The test cycles the ARD fuel nozzle heater on for 3 minutes, or until the test is aborted by the technician.
The 3 minutes will give the technician time to perform an electrical check on the heater. Perform the
electrical test by hooking a current probe around the heater wire to verify that the heater is getting the
proper current. Engine speed must be present while this test is running to allow coolant to circulate through
the ARD head. Once the current has been measured, the test can be aborted.

Calibrations
Cat ET calibrations are listed below.

Injector Trim Calibration

Purpose

Injector trim files calibrate each injector. The injectors are calibrated so the injectors will deliver a precise
amount of fuel at the exact time needed.

Cat ET Location

1. Connect to Cat ET.

2. Select the Service tab.

3. Select the Calibrations tab.

4. Select the Injector Trim Calibration tab.

Calibration Operation

Caterpillar tests each injector to verify the accuracy of the injector duration and timing. If the injectors do
not pass, the injectors are not used. If the injectors do pass, trim files are created and the injectors are
installed. The trim file adjusts the duration and timing of each injector, so the injectors all function the
same. When new injectors are installed, the technician records the serial numbers of each injector and
searches for the injectors in SIS Web. The trim files can be downloaded and stored on a pc. The technician
loads the trim file for each injector into the ECM.

In Illustration 16 you can see each injector that falls in the box is a good injector that passed the tests.

Service Procedures
Cat ET service procedures are listed below.

Dyno Mode
Purpose

Dyno Mode is used to run an engine on a dyno without derates or diagnostic trouble codes tripping from
missing machine components. Normally, while in chassis an ECM is looking for inputs from various
machine components, like the transmission ECM or body ECM. Dyno Mode does not require the CEM to
be installed. If the ECM does not see the inputs, the ECM assumes that something is wrong and sets a
diagnostic trouble code.

Illustration 29 g03137152

4. Select the Ash Service Regeneration tab.

Service Procedure Operation

This regeneration has a fixed length of time that the regeneration heats up the DPF and burns out soot that
has built up during operation. This service procedure is done before an ash servicing has taken place, and
the regeneration makes the ash cleaning more effective.

Manual DPF Regeneration

Purpose

Manual Regenerations are used by the technician to regenerate the DPF and troubleshoot the aftertreatment
system.

Cat ET Location

1. Connect to Cat ET.

2. Select the Service tab.

4. Select the Manual DPF Regeneration tab.

Service Procedure Operation

This type of regeneration lasts a minimum of 10 minutes, and soot loading is at 0 percent. If a problem is
encountered during the regeneration, the diagnostics are tuned to alert the technician. This regeneration also
tests the ARD nozzle for plugging by comparing desired and actual DPF inlet temperature.

DPF Ash Service

Purpose

The engine ash model must be reset whenever the filter is cleaned or replaced. Reseting the ash model
places the DPF ash volume back to the "Clean State". The resetting will allow the regeneration of the DPF
to function properly.

This histogram is populated when the engine system has calculated a condition in which high exhaust temperatures are present.
A fault code will not be logged when the system calculates a high exhaust temperature condition, but will activate a derate to
the engine in order to protect the engine system. This is normal under most circumstances and no additional troubleshooting is
necessary. Refer to Troubleshooting, "Exhaust Temperature is High" for additional information.

Illustration 57 g03137079

There are certain engine conditions that put the engine in danger of turbocharger overspeed. The engines are calibrated and
certified up to a certain altitude and ambient temperature limit. If the engine is operated outside this limit, the engine is more
likely to experience overspeed of the turbo. In other words, the turbo has to work harder to maintain the desired boost pressure.
This is normal under most circumstances and no additional troubleshooting is necessary.
