Q: Failure to connect to scan tool

asked by on August 19, 2016

So I had to fix some stuff did a mod but I need to get my obc off limp mode by ckearing check engine light. My cluster is bad though I think, I'm guessing because my instrument display doesn't work any more besides my gas gauge. The scan tool at AutoZone said failure to connect. Is there anyway to get the codes or check to see if my check engine light went out
