Try with OBDII EOBD and post the results. Also try with the last Aveo model on your tool. I hope that the vehicle will be scanned.
You mentioned that MaxiSys cannot connect to it, so check physically the OBDII connector for wiring fault and use WD-40 to clean the contacts if required.
Support at Autel, please shed some light on scanning through different model and the obtained results.
Thanks.
