*ZDC (Target data container) – The ZDC of the control unit is updated to a new version within the ID.S 5.4.3

KD compound update. If the SW-version is already current, then only the ZDC is updated via the update

procedure without a SW-version change.
17. Support
The possible remedies listed below should only be applied when necessary for the specific errors listed if

such errors are encountered in the course of the software update given in this technical bulletin. Any other

use of these remedies is inappropriate and can lead to unexpected results or additional errors.
1.
ERP8064: Should ERP8064 occur during function restore in the function enabling system (FES), then

there is a connection problem with the backend license server.

Possible remedy: For the purpose of this remedy only, repeat function restore using code

0019S421014 and then repeat action code F543.
2.
ERP8065: During software flashing, should ERP8065 occur, then an action code was used that cannot

be used for the current vehicle and its current software compound / baseline.

Possible remedy: Check the action code used for validity.
3.
ERP8075: Should ERP8075 occur during software flashing, a repair suggestion cannot be determined,

as several identifiers are missing from identification of certain control units or entire diagnosis

addresses.

Possible remedy: Perform a terminal 30 reset (see in GFF test plan list: Important note when

disconnecting the 12V battery) then start a new diagnostic session, and reattempt software flashing.
4.
ERP8088: During software flashing, should ERP8088 occur, the software update or the online

reporting of the updated vehicle build status documentation failed.

Possible remedy: Carry out “5.2 ICAS1 factory reset” again and repeat action code F543.

Alternatively: Carry out a bus sleep with test program 0019 – Establish bus sleep mode. Then repeat

the action code used.
5.
ERP8113: During software flashing, if ERP8113 should occur, then not every update has yet been

successfully carried out.

Possible remedy: Switch off the ignition for 30 seconds. Then switch the ignition on again, wait 30

seconds and then repeat the action code used.
6.
ERP8118: Should tester error message ERP8118 occur during software flashing, then one or several

diagnosis addresses were not recognized during diagnosis entrance. The diagnostic tester generally

shows the affected diagnostic addresses. If no diagnostic addresses are shown, pay special attention

to diagnostic addresses 0075 and 8107, and sub-bus addresses (for example: 0601, 0602, 0616,

0618, 0631, 0637).

Possible remedy: Manually identify the missing control units in the control unit list or perform a

software configuration on the respective diagnostic addresses. In the case of an unrecognized sub-bus

address, perform the software configuration on the corresponding diagnostic address to which the subbus address reports and then repeat the action code used.

Hint: An earlier GFF log, when downloaded from GFF Paperless in HTML format, can be referenced to

compare installed diagnostic addresses and respective sub-bus addresses at an earlier time point

before the start of software flashing.

Should this procedure not resolve the problem, perform a terminal 30 reset (see in GFF test plan list:

Important note when disconnecting the 12V battery) then start a new diagnostic session, and reattempt

software flashing with the action code used.
7.
ERP9999: Should tester error message ERP9999 occur during software flashing, then there are

problems with the connection to the D3 Edge Box dealer workshop server.

Possible remedy: Check the that the control units to be updated are identified in the control unit list,

then contact your IT support to check the URL configuration and software version of your D3 Edge Box.
8.
After the software update the OCU (diagnostic address 0075) is offline, the globe symbol (online

status) is not shown, or is grayed-out in the center display.

Perform GFF: Guided Functions > 0075 – Activating control module

After about 2 minutes the globe appears and is shown in white (online).
9.
Error message: “The CAN-FD/ DoIP communication path could not be set” – If this error message

occurs during the software update process (SVM) there may be several causes.
Possible remedies:

Check and adjust firewall settings with dealer IT network support (see under: “2. Review prerequisites

and perform preliminary work”).

Update Windows operating system of the diagnostic tester.

Ensure that only diagnostic interface VAS 6154A or 6154B is used and ensure the software of the

diagnostic interface VAS 6154A or 6154B is current.

For the purpose of this remedy only, temporarily reconfigure the diagnostic tester for DoIP-only

communication under “Admin > General > GFF Process > Communication path selection” and then

reattempt the action code used. Afterwards, restore setting for automatic detection.

If DoIP communication is still not possible, then check wiring at the diagnostic connection (U31) and

the ICAS1/Gateway (J533) according to the attached supplemental information

“tb_2080124_attachment_can_doip_checks.pdf”.

10. No terminal 15 / ignition cannot be switched on anymore after performing action code S4210F543. This

occurs when ICAS1 freezes in the bootloader. In the identification data of the diagnostic address 0019

the software version 9246 is shown.
Possible remedy:
PR number V7B: Pull fuse SC41 for 1 minute and, after insertion, carry out action code S4210521D.

PR numbers V7C or V7G: Pull fuse SC41 for 1 minute and, after insertion, repeat action code

S4210F543.

11. 0019: DSDL2 incorrect: The DSDL2 cannot be successfully written during the software configuration

(incorrect).
Possible remedy: Pull fuse SC41 for 1 minute and, after insertion, carry out the previously used action

code again.

12. 0051: Error message: Safe condition not created.
Possible remedy: Switch off the ignition, select 1. Create requirements and press Continue.

13. 0602: Adapting/calibration incorrect: The software configuration cannot be successfully carried out

(incorrect). The SFD (vehicle diagnostic protection) at the master (SAM/ diagnostic address 0009)

could not be activated.
Possible remedy: Carry out SFD authorization via Self-diagnosis (OBD) > 0009 > Access authorization

> Authorization manually online and repeat action code F543. A bus sleep may need to be carried out

in advance.

14. 8128: Error message: Active function not completed. The new instances from ICAS3 were not

completely loaded; the ID light is white on the ends.
Possible remedy: Carry out a bus sleep with test program 0019 – Establish bus sleep mode. The ID

light no longer lights white at both ends (the bus sleep mode may have to be carried out twice). Then

carry out action code F543 again.
NOTICE

In case of ERP errors during software flashing that cannot be resolved:

– Press the help / support button on the diagnostic tester to send ODIS feedback.

– If the help / support button cannot be pressed because of a crash of the diagnostic tester, restart the

tester and press the help / support button immediately upon restart. The data of the previous session is

then still available and can be transmitted.
