removing 08 brute engine brake actuator

Actuator Control System Trouble Shooting,
When the actuator fails, the controller enters failure mode and the indicator light illuminates 2WD,4WD alternately.
1. If it alternates really fast at .5 seconds on 2wd and .5 seconds on 4wd then the problem is Selectable 2wd/4wd actuator.
2. If it alternates from 2wd/4wd at 1 second intervals, the problem is the Engine Brake Actuator.
3. If it alternates from 2wd/4wd at 2 second intervals, the problem is both the selectable 2wd/4wd actuator and Engine brake actuator.

Is there a way to reset or determine which one it is, mine is flashing really fast .

There is no reset. You will have to count the seconds each is on and go by the chart to see which one has a problem. I think you said the when you turn off the key you hear nothing from the break actuator, so there is a problem with it or the linkage.

So the actuator on top of the belt cover is what controls 2wd & 4wd and the brake? What bout the actuator in front case? By the way you have been alot of help.

The actuator on the belt case is only the engine brake. The other...on the front diff is the 4wd in & out.

It alternates in 1 second intervals, replace the actuator on the belt cover ?

That's what it says. Check all the connections first. You can also pull it, take it apart and clean it up. Make sure the fork is working correctly and that when you out it back in, the pin on the rotator fits back into the slide bushing it came out of.

Sometimes though....they are just gone and have to be replaced.

I pulled the cover today cleaned the actuator & looked at the forks , on the forks there are like 2 pads made out of plastic , those had some wear on them. Notches where it had been rubbing up against something . Before I had mentioned at times when I turned the bike off the actuator would keep making a noise , that not happening at all now. Do you think a new actuator will fix or will I need actuator & those forks? Do you see any need for me to try to reset the front actuator in the diff , like I did when resetting the the belt light . Once again thanks .

Once the problem is correct, the flashing will quit and they both will go back to working normal.

Thanks for the info. I removed the engine brake actuator and even tho is works dis-assembled it to makes sure all is clean. My indicator blinks about .5 secs so it must be the 4WD actuator on the differential. I will again remove it later and check it better. Going to the camp today and will have to ride 4WD all the time.
I saw somewhere where a guy modified his differential actuator using a choke cable to manually switch from 2WD to 4WD. This may be what I have to do to eliminate more electronic BS on the Brute. In doing so tell me what use is the engine break anyway? Another guy posted somewhere how to eliminate the break actuator as well using a relay but I'll have to find it as well.
