This comprehensive guide dives deep into every aspect of the Esys Plus 402 Top, providing you with the technical insights, practical use cases, and buying advice you need.

Step 1: Driver Installation

• Do not plug the device in yet.
• Download the latest FTDI or OEM-supplied drivers for the J2534 chipset.
• Install the drivers as Administrator.
• Disable Windows Driver Signature Enforcement (for older Windows 7/8 systems).
