Service
The root cause responsible for this defect is currently still under analysis. This PSS will be updated as soon as
further information is available.
1. Do not replace any components for this condition since this will not resolve the customer’s concern.
2. Create a PSS record in the PSS application through the Pending Service Solutions (PSS) link in AccessAudi
(under Related Links >> Service).
3. Our current observations suggest that functionality is usually recovered temporarily by:
a. Accessing the ConBox via the ODIS diagnostic tool.
