Alright.
During rides, if the RPM exceeds 2.5k for about 10 seconds, the FI light will appear and stay lit. After I stop and put the bike on side stand with the engine running. The FI will blink for 2 long blinks, and 5 fast blinks. Indicating error 25 on the service manual. Which is the knock sensor problem.
The mech did checks for me, he checked for loose or poor connections on the knock sensor, its OK. He checked for continuity from the ECM grey connector blue wire to the knock sensor, its OK. The knock sensor wasn't replaced with a new one to test again. That's where he determined the ECM was faulty.
Heard from many BB owners locally they said 99 FI model have this infamous problem with the ECM. It tends to go about 4 yrs from the date it was rolled out from the production line. I wonder how true can that be, thought such things are made to last?
I'll be doing a self diagnosis or maybe a "self diagnosis reset"
Any of you guys done it before? Is there any pros and cons for doing that?
I'll be following what the manual teach.
