Digital Gauges

ScanGauge-D provides real-time gauges to show you what is going on “under the hood” with more than 15 built-in digital gauges. The gauge screen allows you to select and display 4 gauges at a time, so you can monitor the current operating conditions of your vehicle in real-time.

Exclusive Programmable Gauge System

In addition to the standard set of gauges, the ScanGauge-D features the exclusive X-GAUGE™ programmable gauge system; you can monitor parameters such as transmission temperature, trip data and fuel economy information.
