Why is the OBD2 Port Important?

Your Lexus RX 350’s OBD2 port is the communication hub for its onboard computer system. It allows you to connect an OBD2 scanner, a handheld device that acts as an interpreter between you and your car. This connection unlocks a wealth of information about your vehicle’s engine, transmission, emissions, and other critical systems.

“Understanding the data from your OBD2 port empowers you to diagnose problems early, potentially saving you costly repairs down the line,” says automotive diagnostics expert, John Miller. “It’s like having a window into your car’s brain.”
