3. How to Use a 90705 OBD2 Scanner: A Step-by-Step Guide

Using a 90705 OBD2 scanner involves several straightforward steps that can help you diagnose and address vehicle issues effectively. This process includes connecting the scanner, reading diagnostic trouble codes (DTCs), interpreting the data, and taking appropriate action based on the findings.

3.1. Step 1: Locating the OBD2 Port in Your Vehicle

The first step in using an OBD2 scanner is to locate the OBD2 port in your vehicle. This port is typically found under the dashboard on the driver’s side. According to the EPA, all cars and light trucks manufactured after 1996 are required to have a standardized OBD2 port, making it relatively easy to find.

Common locations for the OBD2 port include:

• Under the dashboard, near the steering column
• Below the center console
• Inside the glove compartment
• Behind an ashtray or other small compartment

Consulting your vehicle’s owner’s manual can also help you locate the OBD2 port if you are having trouble finding it. Once you have located the port, ensure it is clean and free from any obstructions before proceeding.

3.2. Step 2: Connecting the OBD2 Scanner

Once you have located the OBD2 port, the next step is to connect the OBD2 scanner securely. Plug the scanner into the port, ensuring it clicks into place. Most scanners will power on automatically once connected, but some may require you to turn on the vehicle’s ignition to provide power.

It is essential to ensure the connection is stable to avoid any interruptions during the diagnostic process. If the scanner does not power on, check the vehicle’s fuse box for any blown fuses that may be affecting the OBD2 port. A faulty connection can lead to inaccurate readings and incomplete diagnostic information.

3.3. Step 3: Reading Diagnostic Trouble Codes (DTCs)

After connecting the OBD2 scanner and powering it on, the next step is to read the diagnostic trouble codes (DTCs). Navigate the scanner’s menu to the “Read Codes” or “Diagnostic Codes” option and select it. The scanner will then communicate with the vehicle’s computer and display any stored DTCs.

Each DTC corresponds to a specific issue within the vehicle’s systems. For example, a P0300 code indicates a random or multiple cylinder misfire, while a P0171 code suggests that the system is running too lean. Record all DTCs displayed by the scanner, as they will be essential for diagnosing the problem.

3.4. Step 4: Interpreting the OBD2 Data and DTCs

Interpreting the OBD2 data and DTCs is crucial for understanding the nature and severity of the vehicle’s issues.
