Been away for a while with work. Got codes C0265 and C0227 so it looks like I will be pulling the control module when the weather warms up. I will try to just remove the module from the motor, but the amount of rust I am finding underneath is not good. Does a replacement module have to be reflashed? How hard is it to replace the brake lines connected to this thing? I am thinking I may have to drop the motor replace the module, and if I go to that much trouble I should replace the rusty brake lines. Thank you to all that are responding.
