I just recently installed a used Professional Radio to replace my broken unit. All the features were the same except the newly installed one had a CD changer feature built in which I do not have currenlty. Surprisingly, the new radio worked with sound without any additonal programming.

When I recently scanned the radio with my BT scan tool under the MOST/CAN gateway CD73 module I received a few faults as follows:

E18D
Wake Up Device tried to wake up network 3-times without success (Error_WakeUp_Failed)
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

E18F
Central registry does not match with debit configuration (Error_Registry_New)
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

E190
Ring diagnosis check done (Error_Ring_Diagnose)
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

E191
Too long and/or too many unlocks (Error_Unlock_Long)
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

I have a few activation functions available that I can use with BT tool:
-Set Production date
-Set Transport date
-Set Service mode
-Set Wake up mode ON
-RAD_ON to supply
-Reset CCC Control Unit

Would one of the functions on my BT Tool clear these faults? Is the car computer not recognizing my new Radio? Any suggestions would be apprecaited.

cd-changer is communicated over MOST bus
you radio have multiple errors about MOST bus ring
until you code out cd-changer option there errors will come up after every car sleep

Is there any harm to the modules or control units if I don't code out the CD changer?

Read out the 2rad or 2urad file to see what's enabled.
You can turn of the Most Bus by setting ring status to nicht activ.
I am not sure if I spelled activ right but you should only have
to add of subtract nicht.

This is from my pro radio with Most but I have Most
Change RING_STATUS to nicht aktiv to turn off the Most
Bus. CDC should say nicht aktiv to if you don't have it.
I would think your default coding the VO should have established
your original code but I would hand code it to be sure.
