Delphi's patent-pending Buzz Tool, also known as the Electronic Injector Test Kit, combines multiple tools into one to test the electrical integrity of all-makes solenoid Common Rail injectors.
The Delphi Difference
Measures resistance and inductance of the coil in the injector
Tests for coil open/short circuits
Checks the insulation of coil to injector body
Drives the valve to make it BUZZ, proving the valve is not stuck
Significant time and cost savings
