The Holset E-tool (pictured below) allows our turbo technicians to carry out function test on Holset electric actuators, identifying faults to either the actuator itself or within the internal turbocharger VGT mechanism. 

The Holset E-Tool also allows our technicians to install and calibrate electric actuators to the corresponding Holset VGT turbocharger, covering all applications including the HE400VG & HE500VG turbochargers fitted to the Cummins ISX CM871 series engines.
