I have a DMC that I do a selector set up selector reads sup. Selector variables read BDL high, dz low, lu high , and ld low. Clear CLC faults. The second I push safe and up, the CLC gets a 020-003 fault, and selector starts blinking. MIND you car hasn't even moved only motor starts. Originally lost CLC & software, Installed dk13 and had CLC, and all boards sent to access electronics the comm chips were all bad, replaced all tested together. Any help is appreciated.
