Unfortunately, you cannot get a full park assist PAM and not connect the front sensors. If you connect just the rears, it will throw a DTC and then disable the rear sensors until you clear the DTC. 

I have never worked out how the ford numeric part numbers translate. I have seen the full alphanumeric numbers with 2 different numeric part numbers so not really sure how it works.

I have always purchased everything based on the numeric part numbers from the catalogue. 

With the wiring for the heated seats, you may find like I did, that the wiring for the seats are in floor loom, but not in any of the other looms. However, there is a big connection by the passengers foot well that connects the floor loom to the rest of the car. To pick up the wires for the switch I ran wires into this connection. I also had to run wires to this connection for the parking assist switch.

It seems that Ford put in the top spec floor loom in most of the focus' but not all. So if I was you, I wouldn't assume that because the wiring is there for the module, it's there for the front sensors. 

There are 3 looms involved in the heated seats. The floor loom which you obviously have as the fuses are there. All the wires from this go direct to the seats (power, GND etc). 

There is then the centre console loom. This connects to the 54pin plug at the front of the console by the passenger footwell (to connect to the dash loom). This, it seems, you don't have. This does the 12v sockets front and rear and also the media hub. This also contains the heated seat button illumination and level select wires on the version for heated seats. 

The last loom is the dash loom. This only supplies a couple of wires, most of which are shared with other things in the car (button illumination and 12v for the level select). The 2nd wire is a 12v signal from the BCM that selects the heat level when you change the heated seat level button. But it is purely just 12v, it doesn't change anything and the same wire is used by 4 or 5 things in the car. Because these wires are shared with other systems, they are usually there. They were on mine even though every other wire was missing. 

So for heated seats, you probably only need a centre console loom and the buttons (and obviously seats). 

You will be able to tell if the dash loom has the wires you need by looking at the connectors on the actual seats. If there is a brown wire going to each seat, this is the level select and ultimately comes from the dash loom. 

Make sure you disconnect the battery for a while before removing the seat connectors because there are airbags.

On my car, I didn't have the pins in the connection going to the centre console C33C, but they were in connection C23A pins 12 & 13 (both these connections are in the passengers footwell but connection C23A is more forward). So I picked up the 12v from the yellow wire going to my heater module (on the wiring diagram it's the same circuit) this us the input to the switch. And then the outputs I took down to connection C23A. So I guess I'm saying, just getting a centre console loom may not work. 

Nothing is guaranteed with Ford. 

But even if the wires are not there it's a simple fix. The BCM provides a 12v supply to the heated seat switches and there is a variable resistor in the switches. This then sends a resistance value to the seats that tells the heated seat how hot you want it.

I thought that might have been the case re the PAM, thanks for confirming!

Do you have a link to the catalogue you use? I tried searching online earlier via what appeared to be the official ford site but didn't have any luck 😞

thanks both for the info on the heated seats - it'll come in useful should I decide to go down that route 🙂

I have always used this:

https://ford.7zap.com/en/car/

You can use it in 2 ways. If you enter your VIN then it will only list the items you have on your car. 

If you enter the details line by line (i.e. year, month, territory etc) then it's shows you all the items for a focus. 

You can get all the items from Ford ETIS.

Awesome thanks..I'd used the link to find out looms etc as you suggested in an earlier post, its really useful to know - especially when it comes to looking up parts for focus' in general.   I wasn't aware you could then use ETIS, that's the missing piece in the puzzle

Hi,

I have a 2012 MK3 Focus and I'm going to swap the bumper but this probably sounds a simple question..

On the genuine ford bumper do the parking sensor brackets come off via clips or are they sonic welded on and really hard to get off? is there a guide or procedure for taking them off?

Thanks for info.

The brackets just unclip. You squeeze them at the back and push them out from behind. A little bit tight but not really a problem.

You have to remove the actual parking sensors first. These come out from the rear of the bumper. They are held in the brackets by 2 clips. You just push these clips outwards and then push the sensor from the front. 

Hi all 

reading through all the posts I have fitted OEM rear parking sensors to my focus  ST-2 and all working ok now I’ve purchased front sensors and made my own loom up can I fit just 4 sensors to the front as don’t want self parking will the module accept just 4 sensors to the front ? 
 

thanks

also if anyone has fitted the blis modules could you message me please as stuck on where to connect the can wires.

many thanks

I have not tried it, but would guess the answer is yes, you could just fit 4 on the front. Then in FoCCCus you just select front and rear for parking assistance instead of Front, Rear and SAPP.

But if you are fitting 4, it's not a lot more work to fit all 6 and you don't have to enable semi automatic parking but will gain front side protection. 

The PAM modules on the Focus cannot be modified (they have non configurable AsBuilt) except for the very latest Focus models. So if it does complain about having 4, you can't really do much about it. 

I do know that if you go for the full front/rear PAM module, it doesn't work at all if you do not connect the fronts.

I have not fitted BLIS (yet), but there are CAN wires on the PAM module that you should be able to tap in to. 

Would you know which Pam I would need for just front and rear sensors no self parking 2016 focus 

There isn't one. They do 2 PAM modules for the Focus. Rear only which has a part number of ****-******-A*. And then a park assist module which has a part number of ****-******-B*.

Your PAM modules usually start F1ET for the MK3.5. For example F1ET-15K866-AG would be a rear only and F1ET-15K866-BJ would be full park assist. 

But as I say, these cannot be configured so I assume it reads from the BCM so 4 front sensors may be possible as some MK3 Focus were only fitted with 4 at the front. 

You may well be stuck with using 6 sensors as I think all MK3.5 Focus had 6 sensors but could be wrong. You cannot use a MK3 module because the IPC software is different. 

Thanks mate appreciate your help 👍

So am I right in thinking all 4 rear sensors are the same bracket for a 2014 hatchback standard? Got all parts and just trying to sort brackets? Ford.7zap is showing 2 different ones but ive just fin reading 17 pages on this thread and someone mentioned they are the same if its the 4 rear ones?

If anyone has any or can link some in Frozen White that might be compatible, lmk 🙂

There are 2 brackets for the MK3 hatchback rear. The inner brackets and the outer brackets. 2 of each. All the actual sensors are the same.

All above will need to be painted your bumper colour. Or look out on eBay for used parts that already come in your colour.

If you want original Ford sensors that are already Frozen White.

Thanks man! This is what i'd been looking at - was hoping I could just use 4 of the £12.99 ones 😞 It's over £58 for 4 bits of plastic. More expensive than any of the other parts I got and I wanted to do everything under £110 😞

I already had rears on mine so I don't know the exact difference between the rear brackets. 

On the fronts, the brackets are very different so definitely not interchangeable. 

I don't know about the rears. Probably best to get what Ford specify otherwise they may not fit flush once you cut the holes. 

i've got loads of bits of wiring today, so i'mgoing to post and read when i'm a bit more sober

so i've got the pics and here they are
this is the front loom (i've got loads of questions as to how the plugs are laid out and which is supposed to go where, but i've got a more serious question in that the other loom i have has 4 29db sensors and 2 36db sensors while this one has 5 29db sensors and 1 36db sensor

whats going on?

as for the rears, i've got this plug, so it's all to do with the wires coming out the other side on the body rather than what's coming from the bumper right?

and i'm also further confused by a post i can't now find that states that i need a 6 sensor rear loom for the self park functionality

can't i just plug in the front loom and turn the self park on?

thanks
