Using an Innova OBD2 scanner is a straightforward process that can empower you to understand your vehicle’s health. This guide provides a step-by-step walkthrough on how to use an Innova OBD2 scanner to read diagnostic trouble codes (DTCs), commonly known as check engine lights.
Establishing Communication with Your Vehicle
First, locate your vehicle’s OBD2 port, typically found under the dashboard on the driver’s side. Connect the Innova OBD2 scanner to the port. Next, turn the ignition key to the “ON” position (do not start the engine). This allows the scanner to establish communication with your vehicle’s onboard computer. The scanner will automatically detect your vehicle’s VIN and connect to its computer system. Note: While some advanced Innova scanners may require a running engine for certain features, it’s generally recommended to start with the ignition “ON.” If you need to run the engine, start the engine before connecting the scanner.
Accessing Diagnostic Trouble Codes
Once the connection is established, the Innova OBD2 scanner will display any detected diagnostic trouble codes. These codes are often prioritized by severity. Each code will have a description outlining the potential issue. If multiple codes are present, use the up and down arrow buttons on the scanner to navigate through them. For a deeper dive, press the “System Status” button.
This menu allows you to select specific systems for diagnosis. Common options include “global OBD2” (for engine-related codes) and “ABS” (for anti-lock brake system codes). Use the arrow keys to highlight your desired system and press “ENTER” to proceed. An Innova OBD2 code reader can help pinpoint the source of various vehicle problems.
Disconnecting the Scanner
After reviewing the diagnostic information, turn the ignition “OFF” before disconnecting the scanner from the OBD2 port. This ensures data is properly saved and prevents potential damage to the vehicle’s computer system. The Innova scanner will store the retrieved vehicle data in its memory for later review. Using an Innova scan tool makes diagnosing car problems accessible for everyone.
