    Check Engine Light Never Illuminates

    Hello,

    My check engine light does not illuminate when turning the ignition to on or at any other time. I have checked the bulb itself and swapped with a bulb that I know is working but the light will still not illuminate. When I purchased the vehicle in November, I adjusted the idle per instructions and when unplugging the IACV, the light illuminated as it should. After resetting the ECU fuse, it has never again come on. I've checked all fuses and they are all okay as well. I have also bridged the service connector and no luck there either. Any thoughts?

    Could this be an ECU issue?
