Is my PSdZData file too old? Something else I did wrong? Currently getting trailer hitch electrical/bulb fault. Any ideas?

Should I post this question elsewhere
To retrofit "trailer lighting module" (which I assume you to mean the trailer hitch), you need to program it with ISTA or pay the dealer.
