I was trying out the latest of Ecuflash this morning, as it was a hot day I left the engine running with the aircon on. Took out my laptop, hook it up and tried reading the ecu while the engine is running. It immediately killed the engine, and CEL came on with CC blinking. Afterwards, I reset the ECU but the CEL didn't go off. So I removing the battery terminals and the CEL doesn't go off either.
Did i fry something or can any expert tell me how can I get rid of the CEL?
Thanks.
