Exhaust brake not working in cruise control after Y78 recall

[Bug Out]

Ever since the Y78 recall was completed, the exhaust brake does not slow the truck down while in cruise control. This applies to either Full exhaust or Auto Exhaust brake. I have been back to the dealer 4-6 times and reflashes done etc to no avail.

Prior to the Y78 recall, it would slow the truck after exceeding the set speed by 2-3mph and increase the braking more up to and including downshifting to slow the truck. Nothing now. Can coast as fast and as long as the downhill is available.

Recently emailed the service guy who was helping me with the issue but received no response. Anyone heard of a fix for this issue ?

If I turn off cruise it will slow the truck etc, but not while cruise is activated...
