This test is used to verify the aftertreatment fuel injector is operating properly by inspecting the nozzle spray and measuring the amount of fuel dispensed.
Before running this test, you must:
o Remove the Aftertreatment Fuel Injector from the exhaust system.
o Cap the injector’s mounting hold to prevent exhaust leaks.
o Perform an Aftertreatment Maintenance Reset using the ‘All’ option.

Performing an Aftertreatment Injector Flow Test without removing the Aftertreatment Fuel Injector could result in vehicle damage.
