Recode or Long Coding Screen
Corresponds to VAG 1551/1552 function 07
Recode is used to set various options
in a Control Module.
Warning!
You should refer to the Factory Repair Manual for your
particular car (or some other documented procedure) before attempting to
Recode a Control Module. At the very least, write down the original
values, saving an AutoScan is a great way to
do that. There is no other way to "undo" or restore the original values
if what you're trying to do doesn't work out.
Notes:
-
Some Modules require a valid Login before you can re-code them.
-
A feature unique to VCDS:
You can leave the Work Shop Code
unchanged, or enter any workshop code you desire. Certain other programs
always leave a tell-tale WSC when you re-code a module.
-
The Importer Number is only relevant
for recoding controllers that use KWP-2000. By default, this will remain
unchanged unless you have set up an Importer Number in the Options screen.
-
Up to 20 lines of coding chart data can be included in a Label File.
This data is shown in a balloon on the coding screen.
VCDS can show coding "charts" when appropriate information is available
in a Label File for the control module in question. A balloon will
appear after a few seconds if the Label File contains the appropriate
information:
Airbag Coding: When coding new Airbag Modules in many VW
models, VCDS can "Suggest" an appropriate Coding value
based on the Index number of the airbag controller. This
feature is available only when VCDS is used with one of our
Professional Grade (HEX) interfaces. Disclaimer: We cannot guarantee
that the coding which VCDS may suggest will be correct, but
there should be no harm in trying it. If it's not correct, the
control module should refuse to accept it and the coding
will remain at 00000. To access this function, click on the
[Coding Helper]
button. See the
Aibag Coding
page for more information.
Follow the instructions on the screen
to locate the index number for the airbag controller:
As long as the Index entered is valid and documentation
exists in the appropriate label file, the new Coding (either
short coding or Long Coding) should be entered into the Soft
Coding field:
Coding of Slave Modules.
On the latest cars, many "slave" modules are codeable. The
coding screens (both regular and "long") will present a
drop-list of available modules which can be selected for
coding:
Battery Coding Assistant
For cars that require a replacement battery to be coded in the
61-Battery Regulation module use this function. Note that the 10
digit serial number may be preceded by the battery vendor code, for
instance VAO for Varta. If the code is VAO25402160104 then drop the VAO and just
enter 25402160104:
On some new vehicles like the 8T0 (Audi B8 platform), the
Gateway Installation is not accessible via Long Coding. In such
cases, use the [Installation
List] button in the Open Controller screen for
CAN Gateway to access this screen. This function is
available in all Gateways that support an Installation list and is
explained on the Installation List
Page.
Long Coding. This function is needed to
Code some control modules in the newest cars which use CAN for
diagnostics. Due to the complexity of Long
Coding strings (up to 255 bytes of hexadecimal data) we've
accommodated (and urge) the use of Copy & Paste in this
function
and usage of the Long Coding Helper.
Long Coding Helper is used with
applications such as Niels Ezerman's excellent LCode.exe
(included with the latest distribution of VCDS):
Click on each of the Byte numbers in row
3) and you'll see the selectable options below. Check or Un-check
the boxes for the desired results. Example: "Adaptive Cruise Control
(ACC) installed". In some cases, there will be a drop-down menu
that assigns the correct bits for more complex operations that require
multiple bits to be changed .
Close the Long Coding Helper by clicking the Windows X box on the top
right of the screen or clicking the Exit button on the top left of the
screen to send your altered Coding value back to the Coding screen.
Use the
[Do It!] button in to save the
new Soft Coding to the controller and return to the Open Controller
Function screen.
Use the
[Cancel] button to return to
the Open Controller Function screen without saving.
