HISS and engine light coming on

at the same time and bike cuts out... it is a 2004 Blade with 20.000miles and did my last 10mile trip home yesterday with the bike constantly cutting out for one or two seconds while HISS and engine light came on at the same time... managed to get home but what now I´m wondering what might be the issue...

 

At the risk of stating the obvious I'm guessing it could be an immobiliser issue with regards to the bike cutting out and the HISS light coming on ??

Maybe worth trying this reset procedure I found
HISS and Oil light on... - CBR Forum - Enthusiast forums for Honda CBR Owners

 

Or does it think its being switched on/off?...............spray the contacts of the on/off switch, check your side stand switch and clutch lever switch (if there is one?)

 

go to the dealers and get them to read the errors stored ,i work on trucks which use a computer to read the errors, what we do is take a note of the errors and clear them down , then run the truck to see what errors come back .
sometimes all it needs is clearing the errors due to daft things like low battery voltage, or it will point us in the direction of a faulty component.

 

may sound trivial but did you check the battery contacts
are secure and clean.does the hiss/engine light flash as in showing
you a fault code?

 

hiss/engine light is not flashing but what i have noticed now the bike is back in my garage engine will not start at all and when i turn on the ignition the fuel pump does not power up

 

maybe a faulty or dirty kill switch or a fuse has blown with something shorting

 

Check ecu connections and clock connection also

 

been unable to start the bike all day only turning over pump not priming checked relays wiring etc no joy about an hour ago went to the bike in the garage turned on pump primed started up its the worst type of fault intermittent oh well see what tomorrow brings

 

and the kill switch was okay, clean inside it?

also the bank sensor can cause this too.

 

just thinking as well there is a fuel cut off relay under the
mid section fairing.it can be playing up too.

 

i finally found the fault a wiring fault behind the mid fairing on the right side about a foot back from the ecu is a yellow wiring block this has one live feed in and about six out that feed the fuel pump relay the fuel cut off relay the cooling fan etc the feed in had become loose over time and causing intermittent lose of the fuel pump feed added in a second feed now problem solved
