Service
1. Explain to the customer that a solution is expected to be available by the end of the second quarter of 2024
(subject to change). 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

To temporarily resolve the customer’s concern, perform a terminal 30 reset on the Comfort System Control

manual and remove all three fuses for at least 10 minutes. Once complete, perform the component protection test
