Sorry, just got back to this project and this problem

I managed to get a proper CAN reader/interface that supports SavvyCAN and I still can not receive any messages I configured the Tesla Small drive unit to transmit. I tried to take your advice and transmit messages back to the drive unit, but I am lost as to what message to send the drive unit to test whether it receives messages. I would appreciate a guide on which messages to use for the test and how to format them.

I really need help getting this issue fixed,, as I can not complete the project without CAN messages from the Drive unit. I will appreciate any guidance towards this.
