Frequently Asked Question

Why won't my GS-911 read any of the ECUs?

The GS-911 is not getting any response from the ECU(s).  This could be because of several reasons.

  1. That you are connecting to the wrong (top-box) plug, especially on RT and GT/L models.
  2. That you are choosing the wrong model and is thus talking the wrong protocol (CAN vs KLINE).
  3. The ECU is not powered or not in a condition / able to reply.
    • Immobilizer/Alarm still engaged
    • kill switch NOT in the RUN position
    • Ignition NOT ON
    • Neutral NOT selected.
  4. You are using an extension or adaptor cable with faulty wiring or bent pins.
  5. The diagnostic connection between the connector and the engine controller is severed (highly unlikely, but possible) or short-circuited.

 

The best way to check diagnostic connectivity would be to have the bike in Neutral, and start it... while it's idling connect GS-911 and connect to the Engine controller - If you can connect, then you've had one of the issues in (3) above... if you can't then you might have a (4/5) wiring problem.

If you suspect a wiring problem, also perform the Diagnostic Interface Test to check the connector pins for shorts/open circuits.
