Does anyone here know if there is a way to program the ECU to never show the check engine light? I bought a 2010 Chevy that the CEL never comes on, not even when turning the key to the on position when all the other lights come on. I used a code reader and there were multiple codes that should have turned on the light. I am wondering if the car dealer disabled the CEL instead of fixing all the problems. Thanks.
