ECO button not wrk'g, engine light on
Asked by PeteH27 Aug 01, 2019 at 09:12 AM about the 2014 Cadillac SRX Luxury FWD
Question type: Maintenance & Repair
I saw my check engine light was on, had it checked by a certified cadi repair
tech, was told the error was ECO is not wrk'g causing the check engine light
to stay on. We press the ECO button nothing happens, meaning the dash
indicator ECO light doesn't come on.
Does anyone know how to fix or what i need to do to fix it. Car is out of
warranty, hoping i can fix myself.
