Reason for change
Reason for block
Complaint:
Fault profile 1/2: The display of the COMAND unit (A40/3) or Audio 50 APS (A2/56) shows the message "Theft protection active".
Fault profile 3/4/5: Initial startup of the COMAND unit (A40/3) or Audio 50 APS (A2/56) cannot be performed with DAS/Xentry Diagnostics or is
aborted prematurely.
Cause:
Re. 1. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". In DAS/Xentry Diagnostics go to Actual values/Theft protection
and check the status of the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with
DAS/Xentry Diagnostics was not performed during the last installation. The PIN is still stored in the COMAND (A40/3) or Audio 50 APS (A2/56). The
COMAND (A40/3) or Audio 50 APS (A2/56) locks after approx. 50 activation sequences.
Re. 2. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". Initial startup was performed approx. 2-4 weeks ago and the PIN
has already been redocumented in VeDoc. However, the initial startup was not completed properly due to a procedural error in DAS/Xentry Diagnostics.
Re. 3. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state" and is new from the warehouse. Initial startup cannot be
performed with DAS/Xentry Diagnostics because the PIN cannot be read from the COMAND (A40/3) or Audio 50 APS (A2/56). During initial startup,
the PIN was erased with DAS/Xentry Diagnostics too early to allow initial startup to be completed successfully.
Re. 4. In model series 164 and 251 the EZS/EIS control unit (N73) A164 545 15 08 or A164 545 16 08 is installed. The EZS/EIS control unit (N73) and
the COMAND (A40/3) or Audio 50 APS (A2/56) are not compatible with the "Theft protection" function.
Re. 5. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "CAN signal disrupted" state. The fault code DA00 is stored in the fault memory of
the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup is not possible because there is a CAN fault. CAN communication to the EZS/EIS
control unit (N73) is disrupted or faulty.
Remedy:
Use at least DAS/Xentry Diagnostics version 11/09 with add-on 1352 or DAS/Xentry Diagnostics version 01/10 with add-on 1354!
Re. 1. Perform initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 2. Perform another initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 3. Report the case to your market coordinator with a control unit log of the telematics control unit. He will forward the case to Daimler AG
headquarters. They may be able to determine the PIN again. When the PIN has been determined, perform initial startup of the COMAND (A40/3) or
Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 4. Replace the EIS (N73). To do this, determine the part number in the EPC system. Perform initial startup of the EIS (N73) and transfer the chassis
number to the EIS (N73). Be sure to use the correct upper and lower case letters. Perform another initial startup of the COMAND (A40/3) or Audio 50
APS (A2/56) with DAS/Xentry Diagnostics.
