I have a MK4 2012 1.6 EcoBoost Mondeo estate and have attached a towbar with a CAN module for the lights. Being an avid DIYer thought I would try programming it myself.
Started off with ELMConfig and changed the trailer option to 13 pin socket and it worked. Previously all but the tail lights worked, now all the lights work and reverse parking sensors disable when caravan plugged in. The problem was the cigarette lighter and centre console 12V outlets stopped working
So I had a fresh look at Forscan, which I had used to track a stretching camchain on a Mazda 6 2.2D and general DTCs on a galaxy before that.
Now Forscan can view and modify Central Config settings and looks promising.
Plugged it in with extended license and switchable OBD dongle, put the BG9T-14C097-AA.vbf in the /documents/calibrationfiles folder and ran the BCM service.
The usual beebing and ECU error and clock/date resetting and the data is up on the screen. Had a look through but could not find anything on the 12V power outlets so shut down to have a bit of a think.
Then I find that the Bluetooth, Aux input and USB have now been disabled and I have not found a way to get them back
I am on holiday for the next couple of weeks towing the 'van, so I don't want to risk killing the car completely before then or I'll be in trouble.
Using one of the links on the forum, I downloaded BG9T-14C095-AK.vbf. The Forscan info screen says this is the Calibration file for my cars BCMii. Opening it in notepad it says it is a sw_part_type= DATA and it is about 33kB.
Forscan uses BG9T-14C097-AA.vbf as the bootloader and it has sw_part_type= SBL and it is only 11kB.
So is BG9T-14C095-AK.vbf the data I need to restore my missing functions, if so how do I use it? There is a Reset module function I have seen, will this upload the data? Something I will need to look into after hols.
In the meantime, does anyone else have experience of this and can offer a way out, or am I bound to a dealership to reprogram after a bit more trial and error?
Thanks
