The cylinder cutout tests are for the engines that are listed above. The cylinder cutout tests have been added to Version 3.2.1 of the Caterpillar Electronic Technician (ET). This is a special upgrade to the regular Version 3.2 release that was delivered in October 2000. The test is not currently able to run on 793 truck engines if the engine is in chassis. Parasitic loads cause the test to abort prematurely. The test may be used if the engine is removed from the truck and the parasitic loads are reduced.The test is useful for troubleshooting low power, rough operation, misfiring, and excessive fuel consumption. The test is designed to provide satisfactory results without externally loading the engine. The test provides a fast method and an effective method in order to diagnose cylinders without the use of a dynamometer. This makes the test well suited for use in the field. Proper use of the tests will reduce troubleshooting time and repair costs. The tests will also improve troubleshooting accuracy.Do not perform any procedure in this Special Instruction until you read this information and you understand this information.Test Overview
The diagnostic tests compare the performance between the cylinders. The tests can determine if the cylinders have a problem. ET will display an "OK" status or "Not OK" status for each cylinder at the end of the test.There are five tests. One test was added for each of the following engines with standard rotation 3508, 3512, and 3516. One test was added for 3512 and 3516 engines with reverse rotation. The 3508 engine with reverse rotation uses the same test as the 3508 engine with standard rotation.Description of the Test
The firing order is divided and the cylinders are put into cylinder groups. There are two cylinder groups for the 8 cylinder engine. The test for the 12 and 16 cylinder engines
