Hey every one, my name is mike and I'm new to this site!
I have an 08 4.8 sport x5 and the park break is malfunctioning so I did some reading on this site and found out that its a pretty common problem and also learned how to take the actuator out, at this point i have the actuator out of the car and i have no issues that i can see (bad connections burnt trace wires on the board ect., I tested the motor and it works great and i tested the pwr at the plug and it is present so im wondering if anyone knows what all the diferent wires do? which one triggers to set, release ect. i would like to test it out of the car to see if its a problem with the board in the actuator box or if the problem is in the wiring of the car? any help would be great thanks
