From around the beginning of 2018, more and more FCA models are equipped with a Security GateWay (called SGW) for the EOBD diagnostic system. But what is it and what kind of practical problem does it cause? And what is the solution?
Why is a SGW irritating?
As long as the car is being serviced by an official FCA dealership, nothing is wrong. But as soon as the car arrives at a non-official dealer/workshop/specialist, problems can arise. A few small examples. After an oil change, the maintenance history and the replacement period must be reseted. Universal diagnostic equipment will be used to do this. However, this does unautorized equipment does not get access and no reset can take place.Parameters can be read for a diagnosis, but you cannot delete errors or activate componentsIf internal settings have to be changed with the help of diagnostic equipment. For example, the retrofitting of non-standard options and learning these. For example, shift paddles, cruise control or Race mode. These instruction will be blocked by the SGW.
What is the solution?
We have developed a SGW firewall bridge. This is a small electronic circuit. Not just a set of interconnections (we know from experience that this can cause malfunctions), but one that has been thought about further. The box can simply be installed as substitute for the original SGW.
But watch out
When a car with SGW bridge is connected to an official FCA WiTECH 2.0 diagnostic tool, it will indicate that the SGW has been removed. A dealership who is aware of this will notice that. This can be preventedin two ways
- By reconnecting the original SGW before every service. There are no traces which indicates that the SGW has been disconneced in the past.
- By “de-registering” the SGW control unit. This can be done by having a “PROXI alignment” carried out with for example MultiECUscan. The WiTECH will then no longer notice the absence of the SGW and will not report this.
Is it easy to install the SGW bridge myself?
For the Giulia it is an easy job. Many have done this with succes. For the Stelvio is only ecommended for peolple with skills. Of course the experience counts. So far we can report the following:
- Alfa Romeo Giulia:
Right next to / under the steering column. Accessible by setting the steering column in the highest and longest position. Actually not visible and one has to “look” with the hands. Only to be done by people with not very thick wrists (we have a installation manual available)
- Alfa Romeo Stelvio.
On top of the steering column. Accessible by removing the box to the right of the handlebar. The SGW is not visible and very difficult to reach by hand. Requires a flexible wrist and lots of feeling and agility with fingers (no manual available).
It is doable but only if you are experienced and able to “watch” with your hands.
The SGW bridge can also be used on the following models (delivery in consultation):
- Fiat 500X
- Fiat 500L
- Jeep Compass
- Jeep Renegade
- Maserati Ghibli
- Maserati Quattroporte
- Maserati Levante
