: Open your Delphi software, go to Settings > Hardware Setup , and click the Update Firmware button. Important Safety Tips
It is critical to distinguish between:
Firmware 3201 is a microcode update for the hardware multiplexer used in Delphi and Autocom diagnostic scanners. Unlike the main diagnostic software (e.g., Autocom 2021.11 or Delphi 2017R3), the firmware resides directly on the device's internal chip. Upgrading to version 3201 is typically required to:
Visit the Delphi website ( www.delphi.com ) and navigate to the "Support" or "Downloads" section. delphi firmware 3201 download
The Delphi firmware 3201 is essential for several reasons:
: Supports expanded functions like Intelligent System Scan (ISS) , component activation, and ECU coding for newer vehicle modules. Hardware Compatibility and Prerequisites
Normal during the update. Do not disconnect the cable until the software confirms completion. : Open your Delphi software, go to Settings
Select the correct (or click Test to let the software auto-detect the tool).
Right-click the or Autocom shortcut icon on your desktop. Select Open file location . Find the folder named Firmware inside the main directory. Step 3: Replace the Old Firmware Files
: Navigate to the installation path on your computer (typically C:\Program Files (x86)\Delphi Diagnostics\Firmware ). Upgrading to version 3201 is typically required to:
: Ensure your VCI has a high-quality PCB (usually the "double-board" or "single-board" green PCB with 9241A chips) to handle the 3201 update effectively. Low-quality "black" clones may fail during the flashing process.
Updating clone hardware can occasionally present challenges. Below are the standard error states and their direct fixes. Error: "Device Not Found" or "COM Port Cannot Be Opened"
By upgrading to firmware 3201, you ensure compatibility with newer automotive protocols, minimize connection dropouts, and get the most out of your diagnostic equipment. Always ensure your software and firmware configurations are properly aligned before scanning a vehicle.
Connect the USB cable from the Delphi device to your laptop.
