Nexiq Pro-Link IQ Frequently Asked Questions

What is Pro-Link iQ and why should I buy it?

The Pro-Link iQ is the new standard in hand-held diagnostic scanning tools for commercial vehicles. NEXIQTM product management personnel partnered with service technicians who use diagnostic tools, listened to their suggestions and requests, and designed the iQ as an easy-to-use, advanced, efficient and accurate instrument.
