Navistar NavKal + NEXIQ USB-Link 3 Diagnostic Laptop Kit
The Navistar NavKal Diagnostic Laptop Kit is a complete, ready-to-use calibration and programming solution for technicians servicing supported International and MaxxForce engine applications.
Every EngineDiag laptop kit is professionally configured before shipment. NavKal is installed and activated, the NEXIQ USB-Link 3 Wireless interface and communication drivers are configured, and the complete system is tested so it arrives plug-and-play and ready to use.
NavKal is primarily an ECM calibration-update tool. It can identify vehicle and engine information, display installed ECM software versions, determine whether supported calibration updates are available, install applicable updates, and read or clear active and previously active diagnostic trouble codes.
