A: Yes. In C:\Alientech\KSuite\System\ProtocolOverride.ini , you can manually assign a protocol. Use this only if you know the exact protocol (e.g., ISO15765-4, 11bit ID, 500kbps).

Allow Windows to install the official Alientech/FTDI drivers. 4. Token Limitation and Device Lockouts

If OBD reading fails with "Protocol Not Found," search your ECU type to see if it requires K-Tag, Bench Mode, or Boot Mode to unlock or read the microprocessor. Summary Troubleshooting Flowchart kess v2 protocol not found

If you are utilizing an aftermarket or clone KESS V2 tool, always disconnect your PC from Wi-Fi before launching KSuite. Internet access can force the tool to communicate with official servers, which instantly locks out or erases the protocol licensing on your device.

If you are using a Kess V2 clone, the software can be extremely sensitive.

Inside every KESS V2 hardware unit is a small micro SD card. This card stores the actual protocol files, encryption keys, and token information. Over time, vibration, heat, or data corruption can cause this card to fail, leading directly to the "Protocol Not Found" error. : Uninstall your current software and drivers

Follow these troubleshooting steps in order, moving from the simplest software fixes to more advanced hardware solutions. 1. Software and Firmware Mismatch (The Clone Trap)

Are you using an or a red/green PCB clone ?

Turn off your Wi-Fi or unplug your ethernet cable. Some versions of KSuite try to "call home" to validate protocols; if they reach the Alientech servers with a clone ID, the protocols may be disabled. Step 2: Replace or Rewrite the MicroSD Card A: Yes

Physical connection issues are the most common trigger for protocol errors.

Hardware Connection IssuesThe most frequent culprit is a physical connection problem. If the OBD-II cable is loose, or if the USB cable connecting the KESS V2 unit to your laptop is faulty, the software will fail to identify the necessary communication protocol.
