This is a critical tool for shops that are diagnosting & repairing the newer diesel engines using the DEF injection systems.

The DEF injector electronic pulse tester activates the DEF injector to verify the spray pattern.  The DEF injector must be removed fron the exhaust and the DEF pump must be activated using the Isuzu diagnostic software to pressurize the system.  With the harness that is  included with the tester the DEF injector nozzle is aimed into a suitable container.  The tester is then triggered allowing the technician to visually inspect the spray pattern.

This tool can also be used to test injectors many gasoline engines.

The tester has three different pulse ranges:

• 500 milliseconds
• 10 milliseconds
• 5 milliseconds
