Hi,
When I try to revert back the settings for Traffic Sign Detection (to default no detection, the ACC gets disabled.
There is Byte 24, Bit 6 that is Traffic Sign Detection value in A5 long coding. When I change it back to not activated the system de-activates the ACC at the same time.
Any idea what is causing my ACC to not available ?

Hey mate,Originally Posted by Aus_fas
Did you end up finding a fix for this? I think I am having the same issue.
Cheers

Yes, I did, as I found out there was one bit I shouldn't have touch. Will post the details by this weekend

Okay, here are my notes for that fix.
Now going through the detail:
The issue turned out to be in ACC- 13 module
13 radar:
320047C358FF8428749C8065303085
While I was going through the entire history last night I found out that last month when I first tried to revert the changes. I also changed bytes 1, 4, and 6 of this module. One of the bits in Byte 1 was for traffic sign and that is why ACC was interfering when I have been trying to default Byte 16 /bit 4 of A5.
I defaulted 4 and 6 of the above module this morning but after receiving your email and checked and changed the byte 1 as well. I'm not sure why I changed these one in July. There are possible reason, I may have accidentally entered into the module instead of A5 and then looking at Emergency Assist, Traffic Sign values end up enabling them. Otherwise I see no logical reason to it.
