Refurb your V-boost controller
I knew something was a little off because when I turned on the ignition the V-boost check whine was only going one way then getting stuck. It would only whine once. So, like someone else above said, when I flexed my controller board I could hear the servo motor ticking and grinding so I knew that I probaby had some bad solders on the V-boost controller circuit board. This is what I did to fix the problem:
Start by pulling off the side cover and revealing some relays as well as the VB controller on the right.
Unhook the plugs and pull it off. Then pop the cover off to reveal the circuit board underneath.
Flex the box and wiggle the circuit board out, it should come out pretty easily. Turn it over and take a look at the solder joints. Looks good right? I though so, but apparently it wasn't. The whole board has been dipped in silicone so we'll have to get that off to get at those solder joints.
Using a utility knife, cut very carefully around the outside of the board.
Then start to peel it back gently...
Little bit more....
Finally all the way off, cleanly exposing the joints. Next, use a low wattage soldering iron and VERY carefully touch up the joints. You don't need to add any solder as we are just trying to fix cracks. If you try and add solder ,unless you are very experienced at it, you will most like short something by crossing some connections somewhere without knowing it. Then plug it all back up and text to see if you are whining correctly.
