Adaptive Cruise Control

Hi all,

This is my first post here so go easy on me ;-). Is it possible to get adaptive cruise control for a Mk3 focus? I have have most of the features on mine but I don't know if this is something which could possibly be retrofitted?

Thanks,

Craig

Hi,, i have heard ACC can be fitted but its an expensive thing to do,,

You need quite a lot of new (different) parts - like radar, control
unit, different cruise control buttons, different front grille and
cables etc,, It can be activated via elmconfig too I beleive. A lot of the wiring
will be in place, the plug for the radar is already within the engine
bay etc.

Acc is not part of any pack, It's a stand alone factory fitted option costing £750, and is only available on Titanium and Titanium X so i dont see why it cant be added after sale, just a case of how much £££ i reckon.

Id give Ford services a bell and enquire as to if your car is already kitted out to retro fit ACC,,, but you will probably have to find a Ford tech garage to fit it all maybe.

Let us know how you get on as there may be a few more wondering the same thing. :)

Bear in mind that ACC systems also have to be checked for correct radar alignment and adjusted if needed before leaving the factory.

Then again it'd be interesting to know what the dealers do if they have to replace a faulty or crash damaged unit.

I presume they change like for like, tnen have a set procedure for alignment and testing.

I found this in an article Troy,,,, i could not see a date on the article though.

there's really quite a bit to it when you dig deeper.

Laser-based systems require a clear

field of vision for accurate range finding, so the laser must be mounted

in the grille or behind the windshield (which provides additional

protection against dirt and moisture). Road splash may obscure the

sensor and set a fault code. Radar-based systems, by comparison, are

more expensive but can be mounted behind plastic bumper covers and are

unaffected by dirt or weather conditions.

The adaptive cruise control module (which may integrated into the

body control module) not only interacts with the throttle but also the

brake system to speed up or slow down the vehicle as needed. This

requires a lot of two-way communications, data sharing and feedback via

the vehicle's controller area network system. The active cruise control

module needs inputs from its range finder sensor as well as vehicle

speed, throttle position and braking status so it can calculate and

maintain the proper following distance. Consequently, if there are any

communication faults on the CAN bus, or the vehicle has lost input from a

key sensor such as the laser or radar range finder, the vehicle speed

sensor, or throttle position sensor, the system can't function. The

same is true if it can't communicate with the throttle control system

and brakes to regulate vehicle speed. Any of these faults should set

one or more codes and make adaptive cruise control unavailable until the

problem has been diagnosed and repaired.

Diagnostics for adaptive cruise control systems currently require a

factory scan tool and software to run system self-tests and to check the

range finder's inputs. Replacement modules and range sensors are

currently dealer-only parts, but that will likely change as more of

these systems are produced.

Seems the maker of the unit is Delphi who also fit Volvo's (which is owned by Ford) and Audi's by the look of things.

You can also pick up these units online, so this could be a cheaper option and then get Ford tech's to retro fit and test maybe ?
