2012 etec knock code

[Darrell etec]

Can someone tell me what the knock code means? Never seen it on the hills but coming down the trail two days in a row it gave two beeps and knock came across the dash. Not sure what that means

Needs higher octane or fresher fuel would be my guess

Two etecs and I have never seen that code. Sorry, I can add something more informative.

where did you purchase your last tank of fuel from? what elevation were you riding?

It was new fuel from fast gas in Drayton. I asked a guy up at mcbride he said low octane so i put a bottle of boost in for the second day. Will have to drain it out a try fresh fuel
Thanks for the input
