your break engine is dead....

There are two actuators engine break and 2wd/4wd. Time the flashing to determine which one is bad.
If its the 2x4 actuator some here have removed the engine break actuator and used it there. Many don't feel the engine break as necessary because you will still have engine breaking down to around 5 mph. This is determined by stall of the primary clutch spring.

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.

There also is another Problem it can be that I just had on a Customers bike this week,its a 06 BF750 and it to was flashinf 2wd & 4wd and the code said the engine braking was bad so I replaced it and nothing same deal,so wen threw the book and nothing so it leads back to the Control Box and it was Bad,the is the Black Box beside the CDI Box under the seat,see if you can switch with a buddy to make sure yours isnt bad but this one was and this fixxed the Problem.Hope this can help
