All 650Rs Check Engine Light on (2019 CB650R) DTC 6-7 error code

[lancewong12]

I'm using a 2019 Honda CB650R (with Akrapovic exhaust), after about 3000km mileage the check engine light is on. I've shorted the wires (brown with green/white) to check on the DTC (Diagnostic Trouble Code). It showed 6 long flashes and 7 short flashes. I do not have the Honda DTC manual book, means that I do not have any idea what 6-7 error code means. If anybody could help me out, kindly please let me know what the 6-7 error code means.

I have never tuned the bike after installing the Akrapovic full system exhaust, could this be the problem? Should I just reset the ECU, so it'll learn that it's using the Akrapovic exhaust? Or should it be tuned to fulfill the requirements of the exhaust? Could the 6-7 error code mean that the engine is running too hot, which needs to be tuned, so it would not damage the engine?

Please help.

Grab the service manual from the resources section. The dtc codes (and how to test/resolve them) are in there.

The bike will not need a tune if the exhaust has been properly installed.

Please describe how you counted the 6-7 code. 6 long blinks then 7 short?

Or a video would be great.

6-7 isn't a valid code according to the 650R service manual.

^ agreed, my USA model service manual lists no such code. Perhaps differences in OP's Asian market model?
Further research needed.
