You pull out your trusty Innova Scan Tool 3100, plug it in, and… nothing. The tool shows an error message, “Permanent Failure.” What does it mean? How do you fix it? This guide will help you understand this common problem and provide solutions.
Understanding the “Innova Scan Tool 3100 Permanent” Error
What It Means
The “Innova Scan Tool 3100 Permanent” error indicates a serious problem with the tool’s connection to the vehicle’s ECU. This often signifies a hardware malfunction, software glitch, or incompatibility issues. Let’s delve deeper into the various aspects of this issue:
