#Purpose

The Cylinder Cutout Test is used to perform a test to verify that the Injectors are working. The process involves "cutting out" and subsequently restoring power to a selected cylinder. Other cylinders are then monitored for expected increases in fuel position, delivered fuel volume, or injection duration, depending upon the application. If the value does not increase, then the selected cylinder was not working prior to being "cut out" for the test.

#Accessing

To run the Cylinder Cutout Test:

1). Select Diagnostic Tests from the Diagnostics menu.

Figure 1.2 - Diagnostic Tests (Diagnostics)

2). Then select Cylinder Cutout Test from the submenu. The Cylinder Cutout screen appears.
