sensor, which are very unlikely for the customer to experience again.

Production Solution
This bulletin will be updated when more information is available. A solution is currently under development.

Service
1. Explain to the customer that a solution is expected by the end of Q3 2022 (subject to change) and that no
repairs are necessary at this point. Do not replace any components for this condition since this will not resolve
the customer’s concern.
