No, the 2/4WD actuator failure has nothing to do with the EBC actuator function. They have 2 different circuits. However, they are controlled by the same brain (black box, aka Controller). It's strange that you see the 1-sec flashing FULL cycle interval and the EBC is acting up. Counting exact flashing interval can be confusing.... The bottom line is your EBC is not working and that needs to be checked out.

 

i'm still having the ebc actuator problem with the brute, been doing some reading and have heard of some talking about a speed sensor which controls this as well, does anyone know where it is located and how to test it?

 

Any update on this? I am having the same exact issue with the EBC and the 2wd/4wd flashing but on a 05 750.

 

no luck yet still hoping for a response.
