How to perform Cylinder Cutout Test using CAT Caterpillar ET Software?

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.
Test Operation:
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.

-Connect to CAT ET Software,
-Open Menu: Diagnostics – Diagnostic Tests – Cylinder Cutout Test

-Click Start, then Select Cylinder Cutout Test
for Example: choose 1-Cylinder Cutout Test

-Click Continue, then OK

-Wait until All Cycle Test (Cylinder 1-6) finished, and look at the Results on Fuel Position tab, the smallest value than the others, indicates that could be damaged on Injector (for Example: Cylinder 1).

NOTE:
1-Cylinder Cutout Test Conditions,
The following conditions must be met for the Automatic Cylinder Cutout Test
1) Engine Speed must be between 980 RPM and 1020 RPM (Engine Speed will automatically adjusted)
2) Engine Coolant Temperature must be 170 Deg F or higher
3) No Engine Performance related active diagnostic codes are allowed
4) No default Injector Serial Number (000000000000) allowed
5) Throttle position must not vary by +/- 5%

If at any time any of these conditions are not met, the test will automatically aborted.
-Ensure Transmission is in Neutral or Electrical Load is removed from Generator.
-Fan cycling, A/C compressor cycling, or changes in Engine Load will invalidate this test.
-If the fan is not controlled by the Engine ECM, please Enable the fan if possible.
-WARNING: If the ECM controls the fan, the fan will be turned ON automatically upon starting this test.
-WARNING: Please make sure the Compression Brake is in the OFF position. During the test, Compression Brake operation will cause the Engine to surge.
for Example: 1-Cylinder Cutout Test Aborted

Manual Cylinder Cutout Test
-Click on Change – Start – Stop tab, and look at Fuel Position value.

Being a Heavy duty mechanic I found it quite frustrating to buy a reasonably priced CAT SIS ? diagnostics software and CAT III 317-7485 adapter for CATERPILLAR? equipment. I also prefer to have everything installed on a laptop since I do not want to have to deal with installation, drivers, setup, activation, updates, etc… I just want something to PLUG and PLAY out of the box!

I service mostly HEAVY DUTY equipment like CAT Caterpillar ET? Trucks, HIGHWAY and OFF HIGHWAY equipment and needed a DEALER version to service our CAT equipment since my local dealer was gouging the living hell out of me! It was like have a 2nd ex-wife leeching me! (One Ex is enough!)

We have done work on CAT? Excavators, truck engines, tractors, loaders, dump trucks, backhoes, combines, asphalt pavers, compactors, graders and more. I wanted to share a good experience I had with buying this CAT ET SIS 3 III USB adapter 317-7485 TOUGHBOOK package from the folks at cnautotool.com

The Heavy Duty Diagnostic CAT ET SIS unit they sell came ready to go out of the box with a refurbished Panasonic Toughbook CF-30 (NEW adapters) which I think are the toughest laptops ever made! No wonder the police and military guys use these… I sure would not do this with my slim little Lenovo! (I dropped it once and had to replace the shattered screen)

Other software that was also included as a bonus was

Allison
Bendix 6.3.8.0
CAT Caterpillar? Dealer Version SIS ET? Highway + Off-Highway equipment
Detroit Diesel DDDL 7.05 + Detroit Diesel DDCT + Detroit Diesel Calibration Tool
International ICAP, IPTS, NETS, IPC + – International Master Diagnostic
V Macks 2.6.12 + – V Macks Dealer Pro
Meritor and Wabco Diagnostics
Eaton Service Ranger 3.2
Cummins Insite
Perkins EST 2010B
Volvo VCADS 2.35.10
Nissan – Toyota
Hino 2.0.3.

If you are working on equipment that is not CAT then you will probably need a package with the NEXIQ 2 USB adapter, that can work with Cummins engines, etc… I also like the fact that you could choose a MUCH FASTER SSD hard drive! If you have never used an SSD, welcome to the future! These hard drives are FASTER, more reliable (no moving parts), lighter and even use less battery power.

I had bought another package like this previously from some other Chinese seller because it was so cheap, but I kept running into CAT ET SIS Expired license error then CAT ERROR 142 baud rate, CAT ERROR 231, CAT ERROR 275 and CAT ERROR 434. It was one nightmare after another.. so keep in mind the cheapest price can also ending costing you more in your pocketbook in the long run, plus lost billing time and I think I lost some hair as well on that one! I almost took a hammer to my poor Lenovo like this guy!

Bottom line is I recommend a Toughbook since it designed to be used outdoors in the bright sun (most laptop screens will wash out competely in bright sunlight, but not his one) Can handle sand, dirt, rain, being dropped is no problem as well. I will never use a Lenovo or Dell for my expensive mechanic software again due to the cost and hassle of reinstalling and licensing if the hardware fails.

Do it right and do it once. I hope this helped someone else from losing their hair from frustration

How to perform: Injector Solenoid Test using ET Software (CAT Engine)?
The purpose of the injector solenoid test is to diagnose injector wiring and injector solenoid functionality.

-Connect Caterpillar ET to your Laptop,
-Open Menu: “Diagnostics – Diagnostic Test – Injector Solenoid Test”
Example: CAT Engine – C11

NOTE: Injector Solenoid Test cannot be performed while the engine is running.

-Click “Power All” and wait the process until complete (Mode: powered), from Cylinder 1 to Cylinder 6.
-On Menu “Test Results”, all the results are OK, indicates that Solenoid Injector still on good condition.

NOTE:
-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. Heavy Duty Diagnostic Cat ET indicates the status of the solenoid as “OK”, “Open”, or “Short”.

Diagnostic Capabilities

Diagnostic Codes
The engine’s Electronic Control Module (ECM) has the ability to monitor the circuitry between the ECM and the engine’s components. The ECM also has the ability to monitor the engine’s operating conditions. If the ECM detects a problem, a code is generated.

There are three categories of codes:
-Diagnostic Code
-Event Code
-Flash Code

-Diagnostic Code - A diagnostic code indicates an electrical problem such as a short or an open in the engine’s wiring or in an electrical component.
-Event Code – An event code is generated by the detection of an abnormal engine operating condition. For example, an event code will be generated if the oil pressure is too low. In this case, the event code indicates the symptom of a problem. Event codes indicate mechanical problems rather than electrical problems.
-Flash Code – Diagnostics and events are reported via flash codes. When a diagnostic code or an event code becomes active, the specific condition is immediately reported to the operator through a series of flashes on the CAT ET Diagnostic Software . By counting the flashes, a numeric representation of the diagnostic code or event code is revealed.

Codes can have two different states:
-Active
-Logged

-Active Codes
An active code indicates that a problem is present. Service the active code first. For the appropriate
troubleshooting procedure for a particular code, refer to the following troubleshooting procedure:
a. Troubleshooting, “Diagnostic Trouble Codes”
b. Troubleshooting, “Event Codes”
Refer to the Troubleshooting, “Diagnostic Code Cross Reference” for information that relates to converting flash codes to the equivalent diagnostic code or to the equivalent event code.

-Logged Codes
The codes are logged and stored in the ECM memory. The problem may have been repaired and/or the problem may no longer exist. If the system is powered, it is possible to generate an active diagnostic code whenever a component is disconnected. If the component is reconnected, the code is no longer active but the code may become logged.
Logged codes may not indicate that a repair is needed. The problem may have been temporary. Logged codes may be useful to help troubleshoot intermittent problems. Logged codes can also be used to review the performance of the engine and of the electronic system.
