ROUBLESHOOTING AND

ESTING
Troubleshooting trees are provided for resolving the most common T600 tag tester error messages. Because the T600
is a tag tester, it is normal to receive tag failure messages. However, failures can also occur because of an issue with
the TTU. Review this section to understand which errors are a valid result of an OBU failure and which are a result of
an issue with the T600 tag tester itself.
The error messages in Table 6-1 indicate OBU failures. Ensure the OBU is properly orientated in the TTU cradle before
reporting a failed OBU.
