SITUATION
The customer states that after setting a radio station preset with RDS (Radio Data System) active, and then deactivating RDS, the audio mutes briefly while the customer is driving. CCC-ANT FC "DACA watchdog reset" is stored. Note: With the release of DIS V44 this fault is no longer displayed for this problem when performing a short test.

CAUSE
(New) CCC (Car Communication Computer) software error. The problem only occurred after the vehicles software was updated using CIP V19.1, V19.2 or V20.x

PROCEDURE 1
(New) Perform the following procedure using DIS V44 or higher. This test plan will only be successful if the vehicle has CIP software V19.1, V19.2 or V20.x installed.

Perform a short test on the vehicle and diagnose and repair any other faults related to the CCC or the sound system.

Select "Function Selection" from the bottom left menu bar.

Select "Service functions".

Select "Car Communication Computer".

Select "- Add tuner profiles S6512_50003" under "Own test plan" and page right.

In the "Identification" screen is displayed 2 reminders. Read and then page right:

"This service function may only be used for the Car Communication Computer"

"The CCC must be recoded before this service function is executed". This means that CIP 19.1 or 19.2 must be loaded in order for this test plan to operate correctly. If you have a similar customer complaint and CIP 19.1 or 19.2 are not loaded then this test plan will not fix the problem. Troubleshoot accordingly.

In the "Message" screen is displayed the following. Read and page right:

"The coding of the tuner is being corrected. 2 diagnosis jobs are carried out for this purpose"

In the "Message" screen is displayed the following:

"The tuner coding has been corrected"

End test module and perform quick delete of all faults.

Turn key off for 5 minutes or until driver's switch-block LED goes out.

Check functionality of system for proper operation.

(New) PROCEDURE 2
Perform the following procedure only while updating the vehicle software using Progman V20.x. For all other vehicles use Procedure 1.

After the vehicle software has been updated and the "Final Report" is displayed, select the "Finish" button.

Select "Change" and then "Vehicle".

Select "Service Functions".

Select "CCC-ANT" and then "Continue".

Continue in the test plan until the "Final Report" is displayed and select "Finish".

End the Progman session and turn the key off for 5 minutes or until the driver's switch-block LED goes out.

Check functionality of the system for proper operation.

This procedure needs to be performed after any programming/coding until the release of Progman V21 (expected March 2006).
