Active city stop not available

[Guitar995]

I have a Ford fiesta titanium x 2016 and Everytime I turn on the car this message pops up. Sadly I have looked it up but not found too much information about it. I have already checked the battery which is perfectly fine.
Any advice would be greatly appreciated. Thanks!

That feature was not available in North America. But I would recommend that you trace the circuit and check the quality of the negative earth/ground connection.

Also notice the GPS system is not working - GPS

So "Active City Stop"...

In the UK, Ford's Active City Stop is a driver-assist technology designed to help prevent or mitigate low-speed collisions in slow-moving traffic by automatically applying the brakes when it detects a potential collision.

Tells me one, if not several, sensors in the bumpers are not working so the system shuts down, or it otherwise has a fault so it is not enabled.

They can look like this...

...OR...
Look like this...

Mount in holes and are clipped onto the holder

​

Since GPS is not working - it may mean a major electrical fault is at play here...check your fuses - and I mean all of them.

The Owners Manual might be able to provide some direction as to where those Fuses are located.

Considering how delicate these are, inspect and investigate your cars exterior for damages - make sure you didn't get hit when you were parked somewhere and these sensors got damaged.

Hi!

My apologies for the late reply.

I have checked, cleaned and tested all of the sensors as well as replaced a good chunk of the fuses including the active city stop one with brand new fueses, and sadly it has not been fixed
The only other thing I can add to this is my car was stolen then recovered before I bought it, this sadly means that my keys are not orignal. as they are not the orignal admin keys, my key does not work either which seems to have a setting for active city stop.

I am waiting on a OBD2 scanner which should be coming soon and I hope to reset mykey though forscan


Do you think, as my car was stolen in the past as well as the keys notbeing orignal that it could casue active city stop to not work?


Thanks

No, sounds more like, during the theft, they disabled, or removed a key module that has the programing in the module - to access, perform and report on the City Stop function. So it (the function) remains blacked or blanked out until it's restored. If you needed more information - look for clues as to what else that module may have done - like your GPS, which offers a stronger clue as to the module that would do this type of operations.

GPS requires satellite and triangulation to work so it calculates using programming the module stores inside it to operate. If that Module was removed, or disabled, GPS can't report your location to you or to any other method of tracking the systems anti-theft system that module had - would use to send data or ask for help. The Module would also have some sort of antenna and position monitoring so it can utilize the vehicles proximity sensors as a driving aid to keep you a safer distance away from other drivers more-so than many would otherwise keep a safe distance from; in stop-start and heavy traffic conditions. Its possible to- over-drive (forget to compensate space ahead for) the vehicle you're in as if you're transferring your visual cues into the vehicle ahead of you - (like training) hitting a vehicle causing a crash - because the operator got too comfortable and too close to the vehicle ahead of it and when the other driver needed to evade or come to quick stop - you added your momentum to the incident.

That's what City-Stop helps reduce, but to accomplish it, requires GPS and the use of those sensors.

So if the module for the programming to perform that function is not there, the system is expecting it, it's just not receiving any data about it trying to look for the module to be there and answer it's call-out.

The type of OBD programming needed to see this module is above and beyond many type of the simpler Hand-held check engine light types - this one requires either Forscan or a Ford dealership to investigate and see if the module is needed - possibly for MOT (inspection issues) but otherwise the vehicle doesn't require it because the operation is passive. Meaning- it's there as an observer, nothing more to help report information to you or anyone else whom may be monitoring for it else it won't affect operation except to annoy the operator with those messages and no GPS - except for the City Stop function which may be required in certain countries.

Hello again! Sorry for the late reply

After further investgation, I have found out that the collision detection modual is missing. we have found the plug for it and I am looking at getting one.

im looking at buying this one:
https://www.ebay.co.uk/itm/17479947...OkEbxGU+QrcR1AGK8TEs1Z9XJc4=|tkp:BFBMgNeKwNVl

Though im a little confused as all of the sensors seem to look exactly the same dispite the car model. do you know if they are all the same or do I need to buy the one linked above as it is from the exact model car I have.

Thanks

The issue of compatibility with the workings you have for that model year - that may be why they didn't or couldn't install one.

There are several "variants" of the module, due to the holder it uses for the mounting location - and to be able to "See" objects and work the SYNC/PCM/BCM units using the CAN-bus (host communication system) so it can warn and look for obstacles, objects and even help you use "Adaptive" cruise control if your vehicle was equipped with it.

Since that module is missing, there's little I can offer to help you locate one that should work just fine, as a drop in replacement and off you go.

• The Problem lies in..
  • if the unit can't talk to the system due to the level of communication protocols it tells the system or it's more advanced than the system was programmed for, it will not work in the car.
  • Same applies to the level of sensor technology included, it has a front-facing sensor for it, but also can utilize the ones for the rear or sides like anti-collision alerts and light indicators for lane drift - but it has to be able to recognize and use the proper wiring and voltage readings and signals it needs from those sensors to work right.
  • CAN-Bus protocols also "upgrade" thru the years - so you'll have to locate one that used for that year - latter revisions - those last two letters or digits in the FoMoCo ID string are tell-tale signs of the revision and the ability to be compatible with what you currently use.
  • Earlier ones? (Last two digits closer to A than Z ) Might work better than latter revision ones for they have to also work with the installed technology and it's signals it produces for it to know what to do - but that also reciprocates back to the ability to work in the technology level of you system - does not always mean the latest and greatest are backwards compatible with the earlier units unless you upgrade them all at the same time.

To help with this, In the USA we can "run our VIN" on the Ford website to give us the details on options and what trim level it has - for the benefit of those looking at accident reports, sales or otherwise - you may be able to do the same to run your VIN and see what it used for these options we are discussing here - The VIN is what was on the car at the times it was made - it's the window sticker - so it may be needed to be run find out what you really have and what can be done to make it work right again.

Thank you so much for all your help! From what I can see after looking at schematics and other examples of my car, I have bought this one (please look at photo)

From what I can from the website 7zap (https://ford.7zap.com/en/car/59/no/0/1843/16676/72590/)

I believe that I have bought the correct one. Hopefully this will fix the issue. Either way I'll keep you updated! Thank you!

Good afternoon! I have some fantastic news. It works! I plugged it into the car and the car recognize it immediately, I can now modify all the hazard spot warnings settings etc.

Thank you so much for all your help, this has been a quite fun experience

Please let me know if I can do anything for you and I'll happily try to help!

Thanks again
