Step 7: Test

• Disconnect programmer.
• Plug interface into PC via USB.
• Open VCDS software → Options → Test. Should show “Interface Found” and firmware version.

Reconnect to VCDS, click "Test" in options, and confirm firmware version. VCDS Software Reliability & Expert Verdict vcds atmega162 reflash

Unlike modern CAN-bus interfaces that rely on hardware transceivers for speed, K-Line interfaces rely heavily on the microcontroller’s firmware for timing. When Ross-Tech updates the VCDS software, they often optimize the communication handshaking. If the firmware on the ATmega162 is outdated (e.g., an older revision like 1.9x or 1.8x), the timing discrepancies between the software expectations and the hardware execution can result in communication errors or the cable being flagged as "unlicensed" or "counterfeit." Reflashing updates this logic, essentially teaching the old hardware the new language required by the diagnostic suite. VCDS ATmega162 Reflash — Quick Guide Summary Tips
