Choosing the right diagnostic tool for your vehicle can be confusing, especially with the variety of options available on the market. Launch Tech, a leading manufacturer in automotive diagnostics, offers tools like the iCarScan and Easydiag, alongside basic OBDII scanners. Understanding the differences between these options is crucial for making an informed decision. This article will break down the key distinctions between iCarScan, Easydiag, and standard OBDII scanners, helping you determine which tool best suits your needs.
What is an OBDII Scanner?
OBDII (On-Board Diagnostics II) scanners are the most basic type of automotive diagnostic tools. Mandated in most cars manufactured after 1996, OBDII is a standardized system that allows you to access basic vehicle information related to emissions.
Key Features of OBDII Scanners:
- Basic Diagnostics: Primarily focused on reading and clearing generic OBDII fault codes related to the engine and emissions system.
- Limited System Access: Typically only accesses the Powertrain Control Module (PCM) and related systems.
- Generic Codes: Provides standardized fault codes (P-codes) that offer a general indication of the problem area.
- Affordable: OBDII scanners are generally the most budget-friendly diagnostic tools.
- User-Friendly: Simple to use, often plug-and-play devices.
Limitations of OBDII Scanners:
- Limited Functionality: Cannot perform advanced functions like actuation tests, special resets, or ECU coding.
- Engine and Emissions Focus: Limited or no access to other vehicle systems like ABS, SRS, Transmission, Chassis, etc.
- Generic Information: Provides basic fault codes but often lacks detailed diagnostic information.
- No Manufacturer-Specific Codes: Does not read manufacturer-specific diagnostic trouble codes (DTCs).

What is Launch Easydiag?
Launch Easydiag (also known as Diagun) is a step up from basic OBDII scanners. It expands diagnostic capabilities beyond the generic OBDII protocol and provides access to more vehicle systems and functions. Easydiag typically works with a smartphone app via Bluetooth.
Key Features of Launch Easydiag:
- Enhanced System Diagnostics: Diagnoses systems beyond engine and emissions, such as ABS, SRS, Transmission, and more, depending on vehicle and software.
- Manufacturer-Specific Codes: Reads manufacturer-specific fault codes for deeper diagnostics.
- Live Data Streaming: Displays real-time vehicle data parameters.
- Special Functions (Limited): May offer some basic special functions like oil reset or electronic parking brake reset, depending on the vehicle and software package.
- Wider Vehicle Coverage: Supports a broader range of car makes and models compared to generic OBDII scanners.
Limitations of Launch Easydiag:
- Limited Software Coverage: Typically comes with limited free software; additional vehicle brand software often needs to be purchased separately.
- Functionality Restrictions: Compared to more advanced tools, Easydiag may have limitations in actuation tests, ECU coding, and advanced special functions.
- Software Updates: Software updates and access to newer vehicle models may require subscriptions.
- Targeted at DIY Enthusiasts and Entry-Level Techs: While more capable than OBDII, it may not meet the demands of professional workshops for complex diagnostics and programming.

What is Launch iCarScan?
The Launch iCarScan is positioned as a more advanced and professional-grade diagnostic tool compared to Easydiag and basic OBDII scanners. It aims to bridge the gap between entry-level tools and professional workshop scanners, offering comprehensive diagnostics and a wider range of functions. Like Easydiag, iCarScan also connects to smartphones via Bluetooth.
Key Features of Launch iCarScan:
- Full System Diagnostics: Accesses and diagnoses all available vehicle systems, including Engine, Transmission, ABS, SRS, Chassis, Body systems, and more.
- Extensive Functions: Includes reading and clearing fault codes, live data streaming, actuation tests, adaptations, ECU coding (depending on vehicle and software), and a wider array of special reset functions.
- Wide Vehicle Coverage: Supports over 115 car manufacturers and thousands of vehicle models, offering broad compatibility.
- Special Function Software: Offers 15+ special reset functions to cover common maintenance and service requirements, such as Oil Reset, EPB Reset, SAS Reset, BMS Reset, DPF Regen, and more.
- Professional Features: Designed to meet the needs of vehicle maintenance technicians and offers more in-depth diagnostic capabilities.
- Free Software Inclusions: Typically comes with DEMO, EOBD2, and 5 free car software selections upon activation, offering immediate value.
- Report Generation: Can generate vehicle diagnostic reports for better understanding and communication.
Advantages of iCarScan over Easydiag and OBDII:
- Wider System Coverage: Diagnoses significantly more vehicle systems compared to OBDII and generally more than Easydiag.
- More Functions: Offers a broader range of diagnostic and service functions, including actuation tests and more special resets.
- Enhanced Vehicle Compatibility: Supports a larger number of car brands and models.
- Professional-Grade Capabilities: Closer to professional workshop tools in terms of functionality and diagnostic depth.
