Hello,
The codes
U0038 PT-CAN Malfunction (TCM ECU BUS-OFF)
U0100-00 : F-CAN Malfunction (EPS Control Unit-PCM)
These can get triggered due to any number of components. It can also be due to a wiring issue.
I have attached the troubleshooting guide for both of these codes below.
Follow those steps as it can help you determine the issue.
Let me know of any questions.
Thank you.
