simps100 Posted June 20, 2020 Share Posted June 20, 2020 Hi all Got a new focus on its way - due to the model year change and dropping the 1.5 auto I’ve not been able to get a factory order but have found a pre built with pretty much everything im after apart from BLIS and have been looking at if this is possible to install as a mod. Ive been reading this thread from the states where it’s been done on a Mustang so im guessing / hoping it should be possible on a Focus over here? https://www.mustang6g.com/forums/threads/step-by-step-guide-to-enabling-blind-spot-information-system-blis-and-cross-traffic-alert-cta.107623/?utm_source=FordOwnersClub&utm_medium=ForumLinks&utm_campaign=referrals&utm_source=FordOwnersClub&utm_medium=ForumLinks&utm_campaign=referrals Does anyone with any better car electronics knowledge than me know where to start with this or have any idea where on the Focus these sensors would need to be wired in? I don’t really have any experience with car mods and this is probably jumping in the deep end so if anyone would be interested in helping out with a mod like this would be more than willing to compensate for their time!

DaveT70 Posted June 22, 2020 Share Posted June 22, 2020 If you have specified comfort pack, which includes rear camera and park out assist, there's a chance that the sensors and the wiring are already there. You will still need to change the door mirrors for BLIS, or add the wiring and change the lens and add wiring into the door harnesses for BLIS then reconfigure using Forscan Quote Link to comment Share on other sites More sharing options...
WarhawkCZ Posted June 29, 2020 Share Posted June 29, 2020 Hi there, I had exactly same question. No BLISS for me. Quote Link to comment Share on other sites More sharing options...
Guy Heaton Posted June 29, 2020 Share Posted June 29, 2020 Wouldn't doing this invalidate the warranty? Unless done by a Ford dealer? Quote Link to comment Share on other sites More sharing options...

Any ideas how I could check and confirm if the sensors are there already? Or is there no way other than removing the rear bumper? If it’s just a case of changing the mirrors and enable in forscan that would be amazing! On 6/29/2020 at 10:43 PM, Guy Heaton said: Wouldn't doing this invalidate the warranty? Unless done by a Ford dealer? That’s a good point - I’ve done some research into it and it seems mixed, for example if I enabled BLIS and had an issue completely unrelated later on from what I understand it would still be covered under the warranty? I guess if as above the sensors / wiring are in place and it’s just a case of the mirror glass being changed and enabled in forscan I may find a Ford dealer to do it without it being ridiculously expensive..! Although I do wonder if I’d find a dealer willing to do it - even though knowing it is possible from a technical standpoint. Quote Link to comment Share on other sites More sharing options...

Are there any guides around for removing the rear bumper on the MK4? Everything I find online seems to be for the mk3. Quote Link to comment Share on other sites More sharing options...

Ive been reading this thread from the states where it’s been done on a Mustang so im guessing / hoping it should be possible on a Focus over here? I’m in the same situation and just taken delivery of a petrol 1.5 auto ST Line X. It has everything apart from driver assistance pack and BLIS so would be interested on how you get on with this. I think I’m going to have to look into getting forscan to see what I can enable without physical mods first. Eg could you enable the cross traffic alert to see if the sensors are there rather than taking the bumper off? Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted July 2, 2020 Share Posted July 2, 2020 Hi Apparently you can switch on driver assistant pack using Forscan or UCDS, there's a topic on Forscan on it. You may need to change the steering wheel switch to enable use on lane centre assist Being an ST-Line X you may not have the wiring for BLIS, you'll have to take the bumper off and see Quote Link to comment Share on other sites More sharing options...

I’ve got a Vignale with Driver Assistance Pack and Convenience Pack so from what I’ve seen on here am very hopeful at least the wiring is there for BLIS - if the sensors are there too would be great and hopefully much more straight forward than I was expecting it to be!

Can you even just buy the button? I have park assist and B&O upgrade which someone suggested means they put the upgraded wiring loom in? 12 minutes ago, simps100 said: Will keep updated once work out proper way of getting the bumper off!

Cheers and good luck! Shame I was unable to pick my options as I would have swapped the pano roof and hud for driver assistance pack and BLIS. Oh well never mind the pano roof will be useful with all the rain we’re having 😂 Quote Link to comment Share on other sites More sharing options...
simps100 Posted July 2, 2020 Author Share Posted July 2, 2020 Thanks! Same - I had a Vignale speced our with everything I have now + BLIS - but due to model year change couldn’t place the order and they’ve dropped the 1.5 engine so settled with this one which am more than happy with - it’s lovey to drive but I do miss BLIS from my fiesta - I guess the issue with all these tech things is you get so used to them!

Do you have a link to the forscan forum where they discuss switching on the driver assistance pack? I'd be very interested in exploring that. I've had a look on the forscan site but it would be great to get a proper link. Thanks, Quote Link to comment Share on other sites More sharing options...
Tommo17 Posted July 2, 2020 Share Posted July 2, 2020 You will need to do more than just change the mirrors for ones with Blis indicator. if like the mk3/3.5 the rear sensors have the cam network cable in the loom and a separate supply for the power hanging with the plug for the sensor loom. You’d also need the blis modules and brackets. Not cheap over £400 each from ford and rare to find on eBay for a mk3/3.5 so in short you’d need 2 blis modules and brackets. A new parking sensor loom with blis and 2 wing mirrors with blis indication on then activate. 1 Quote Link to comment Share on other sites More sharing options...

Then Ford still charge £400 to switch on BLIS Hmm I definitely have the driver assistance pack and convenience pack... but I thought cross traffic alert is only enabled when you have BLIS - I don’t seem to have it at the moment anyway! So in theory I shouldn’t need to remove the bumper? I just need a couple of new mirrors with the BLIS alert light and enable it in forscan? What’s the best way to get the part numbers for the wing mirrors? Quote Link to comment Share on other sites More sharing options...

Quick question - if the sensors are not there any rough idea where the wiring would be or will it just be dangling behind the bumper? Will try find what socket the sensors have to make sure find the right thing! Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted July 7, 2020 Share Posted July 7, 2020 Apologies all, after doing a bit more research, you DON'T get the sensors if you have rear camera. You only get them with BLIS (which includes cross traffic alert). You may have the wiring though, if it's a top spec car, it's normally part of the main cabin harness that comes out the rear or it could be part of the rear bumper harness. Either way, it's bumper off I'm afraid Quote Link to comment Share on other sites More sharing options...
AstroNico Posted July 9, 2020 Share Posted July 9, 2020 Hello, I received my new Focus 2020, I took all the options except BLIS. I will be interested to install it. You can check the wiring on one side only, and by checking there is no pre-wiring I think. I just see the sensors. Quote Link to comment Share on other sites More sharing options...
