BrianC13 Posted April 5, 2024 Report Posted April 5, 2024 So when I connect to my ecu with my laptop everything seems to be fine as soon as I crank the car the laptop disconnects and shows connection error 1019 any suggestions or ideas to fix this Quote
Adamw Posted April 6, 2024 Report Posted April 6, 2024 This error just means the ecu was unplugged or powered off while the PC was connected. It most likely means you have a power supply issue so the ecu is not staying powered up while cranking. What car/ecu? Quote
