Honda HDS HIM LED initialization issues solved by COM1

Helped my Japanese friend to solve his Honda HDS HIM LED issues and HDS v3.101.015 “Interface initialization timed out”. Share experience of it and wish the solutions help others.

 

Connected Honda HIM diagnostic interface to the car, then turned on ignition with the key. HONDA & INTERFACE LED flashed for 5 times at the same time. And then the HONDA LED and INTERFACE LED flashed alternately.

Error message popped up:

Interface initialization timed out. Once, remove all of the cables from the interface device, please, and then re-execute the re-connection. In that case, please make sure that the cable is properly connected. Do you want to retry?

(インターフェイス初期化は時間切れになりました。一旦、すべてのケーブルをインターフェースデバイスから外し、再接続してから再実行してください。その際、ケーブルが正しく接続されていることを確認してください。再実行しますか?)

Professional suggestion from obdii365.com engineers:

– Check the RS232 – USB cable to PC

– Check the driver software installation

– Make sure of the PC with com port

– Setup COM1 in the computer management

 

Then i did solve with COM1 setup.

Honda hds Honda diagnostic system software works ok without any issue.
