These instructions may not cover mechanical/electronic details, they will only list the the diagnostic side (coding etc.). Additional details for the mechanical/electronic work needed are part of the retrofitting instructions provided by the parts supplier (i.e. trailer hitch retrofits) or can be found in the factory repair manuals and wiring diagrams.


Installation & Wiring

Information regarding the Installation can be found in the Repair Manuals, the Wiring Diagrams, the Parts Catalog and/or the Instructions included in the Retrofitting Kit.


Configuration

The following Activations are necessary to ensure that the newly fitted parts are properly recognized and are ready to use.

  • Update the Installation List in the Gateway (J533 / #19).
    • Register the newly added 69 - Trailer Control Module.
  • Update the Trailer Control Module (J345 / #69) Coding.
    • Not all Retrofitting Kits contain Diagnostic capable Trailer Control Modules, some Aftermarket Modules may even be pre-coded. This Step can be ignored for Modules which are not Diagnostic capable.
    • Due to different Control Modules and Equipment in the Car the actual Coding Table is not shown here but will automatically be used by the Long Coding Assistant once you access the Function using VCDS. If an Aftermarket Module is installed, check the Retrofitting Kit for further Instructions.
  • Update the Brake Electronics (J104 / #03) Configuration.
    • Check which ABS or ABS/ESP System is installed. If a MK60EC1 is installed an Activation is not necessary (proceed to the next Step), this Step is only valid for MK60 (from June 6th 2005 / MY 2006+) and MK60-AT. MK70 and MK70M as well as MK60 (before June 6th 2005 / through MY 2005) do not support the Trailer Stabilization Function.
      • Enable the Adaptation Function by performing a Security Access. Additional Information will be shown by VCDS once you access the Security Access Function.
      • Via Adaptation select Channel 056 and activate the Trailer Stabilization. Additional Information will be shown by VCDS once you access the Adaptation Channel.
      • The Activation of the Trailer Stabilization can be tested using a Trailer Test Tool (e.g. VAG 1537/A) by performing an Output Test.
  • Update the Engine Control Module (J623 / #01) Coding.
    • Make sure that the Engine is NOT running, otherwise the new Coding will be rejected. Models equipped with Start/Stop System do have a Shutoff Switch/Button which will deactivate the Start/Stop Function.
    • As a Rule of Thumb, If the Engine uses conventional Short Coding (Coding is 7-digits like 0011312) the Long Codding Assistant does NOT apply. Modules using Short Coding typically do NOT support or require Trailer Configuration Coding. If the Engine Control Module uses a Long Coding the Activation is done in (Long) Coding itself through via Coding Assist. Please also note that there are different Coding Variants for Long Coding.
    • Due to different Control Modules and Equipment in the Car the actual Coding Table is not shown here but will automatically be used by the Long Coding Assistant once you access the Function using VCDS.
  • Update the Parking Aid (J446 / #76) OR Parking Aid 2 (J446 / #10) Configuration, if installed.
    • Depending the exact Model/Model Year either Coding or Adaptation can be used.
    • Due to different Control Modules and Equipment in the Car the actual Setting is not documented here but will automatically be shown once you access the Coding/Adaptation Function using VCDS. A Security Access may be necessary prior to Coding the Module.
  • Update the Rear View Camera (J772 / #6C) Coding, if installed.
    • Due to different Control Modules and Equipment in the Car the actual Coding Table is not shown here but will automatically be used by the Long Coding Assistant once you access the Function using VCDS.


If you are having trouble finding/calculating the proper Coding using the Long Coding Assist please Contact us directly. Make sure to include a complete Diagnostic Protocol (Auto-Scan) from the Car and state which steps/work you have performed yet.
