GM Single Wire 33k - cant send packets

[aceycv8]

Hi,

i have started using your code for GMLAN sniffing on the low speed 29bit bus, i have some codes i would like to send back however when i do it never seems to work or my whole car electronics will reset - is there something i'm missing to get this to work to send 29bit packets back to the car?

Thank you

Hello,
The first think I always recommend, is to try out the arduino CAN examples, top make sure that you can send and receive packets. This will also test that your connection and hardware is correctly set up. Just run the Supported PID example and see if it's able to retrieve information.
