2 FAQs On How To Use OBD2 Scanner

Here are some common OBD II scanner related questions and their answers.

1. What’s the Difference Between an OBD1 and OBD2 Scanner?

The OBD2 device or scan tool uses OBD2 technology and is more advanced than the OBD1 (OBD I) scanner. 
Note: OBD stands for “on-board diagnostic”.

The main differences include:

· An OBD1 scanner needs a cable to connect. An OBD2 device can be connected via Bluetooth or WiFi with diagnostic information displayed through an OBD2 app.

· An OBD2 scan tool supports cars built in 1996 and after (with the OBD II system), whereas an OBD1 scan tool is compatible with cars only made in and before 1995. That’s why an OBD 2 scanner is more standardized than an OBD1 scanner. 

2. What Are the Different OBD II Scanner Types?

There are multiple OBD2 diagnostic code reader types available. However, they’re mainly categorized into two kinds:

1. Code Reader

An OBD2 code reader is affordable and readily available. It lets you read every fault code and clear them. However, the OBD2 code reader isn’t the most advanced diagnostic tool for the OBD2 vehicle, so it can’t fully support manufacturer-specific OBD codes.

2. Scan Tool

A professional scan tool is an advanced car diagnostic tool that’s usually more expensive than a code reader and has advanced features compared to a diagnostic code reader. For example, a scan tool provides access to recorded data that you can playback live.

Unlike a code reader, the professional scan tool reads the vehicle manufacturer and enhanced diagnostics codes. Some car scanner tools may even have diagnostic equipment like multimeters or scopes.
