Ok finally back...so I swappednthe modules hoping one (main) was bad not allowing the main brake to pick. To no avail, after swapping, same issue or problem.
Either on insp or auto, e-brake picks but not the main.
I have a video not knowing if will do much help and a picture of the brake. Video may be too large, but I can send via PM or text
As for the sub-codes...I'm getting 0026 2103 and same for if on inspection 0021 2103.
