Problems and Error Messages
Notes:
When troubleshooting the following problems, make sure that the UDS is
powered up and the Link LED is lit solid green. If the Link LED is not lit, then
the physical network connection is bad. Confirm that you are using a good
network connection.
We recommend that you use a serial connection so you can view any
diagnostic information sent out the serial port.
