Fault code library
LIB-DTCThe official definition is one thing; what the code actually means on the bench is another. Every code here is one we genuinely repair — no filler, no codes we have never seen.
A fault code is a starting point, not a diagnosis. The entries below pair the book definition with what we actually find when the unit lands on the bench — drawn from our own job log, going back to 2016. If your code is not listed, call or WhatsApp 07404 487674 and describe the fault: a straight answer costs nothing.
