This comprehensive guide will walk you through everything you need to know about the Innova 3120e, from understanding its basic functions to using its advanced features.

What is an OBD2 Scanner and Why Do I Need One?

Before we dive into the specifics of the Innova 3120e, let’s first understand what an OBD2 scanner is and why it’s an essential tool for any car owner. OBD stands for On-Board Diagnostics, and it refers to your vehicle’s self-diagnostic system. Since 1996, all cars and light trucks sold in the United States have been equipped with an OBD2 port, typically located under the driver’s side dashboard.

An OBD2 scanner, like the Innova 3120e, connects to this port and allows you to communicate with your car’s computer. This connection allows you to:

Read and Clear Diagnostic Trouble Codes (DTCs): When your car’s Check Engine light turns on, it means the OBD2 system has detected a problem. The scanner retrieves these codes, providing insight into the issue’s nature.
View Live Data Stream: This feature lets you monitor various engine parameters in real-time, such as engine speed, coolant temperature, oxygen sensor readings, and more.
Perform Emissions Tests: The Innova 3120e can determine if your vehicle is ready for an emissions test and identify potential issues that might cause it to fail.
