There are a quite a few threads on JC about VF towbars where in many i have posted a link to another thread that links the
VF, WN Accessory Installation Manual.
This Accessories Installation Manual describes the install process for the towbar and the wiring harness package within the Exterior Structural Accessories section and Eectrical Accessories section respectively. Specifically, for the wiring harness install, it states "once the installation has been carried out, configure the TIM module using TIS2 Web SPS. For further details refere to
Trailer Lamp Control Modul Programming Setup".
Sadly, this later
Setup referenced section doesn't exist within the accessories installation manual itself or within the VF Workshop manual available as PDF on the web. In any case, we don't have assess to the needed service equipment to use the procedure should we know what it is, thus programing for us mortals entails a trip to Holden service department and handing over some $$ as discussed in
this thread.
Once the veicle is programed for a tow bar, you then have a setting within MyLink where you can set that a towbar tounge is attached. This sets the reverse sensors to allow for the towbar itself thus avoiding incessant beeping and also sets the indicators to flash 6 times rather than 3 when a momentary push of the indicator stalk is done in your desired direction.
If you have such an option within Mylink, your vehicle is already programed for a towbar. If you don't have such a setting within MyLink, you need to make a trip to a Holden Service department and give them some $$.
But, if i've suspect/assume correctly, the trailer lamps should work regardless of any programing of the trailer lamp control module... If the lamps don't work, maybe the module itself has a fault or the wiring itself is faulty.
Others in the know should be able to clarify if a genuine ne towbar lamp control module needs programing before it will work the trailer lamps AND if a second hand (old) module is tied to the VIN of the donor 'doore in which case you may also need to wipe the old VIN and insert your new VIN during the programing of it...
