How is the SDA2 diagnostic adapter revolutionising FCA vehicle diagnostics?

The SDA2 diagnostic adapter introduces a significant revolution in FCA (Fiat Chrysler Automobiles) vehicle diagnostics, raising standards and efficiency in the automotive industry. Modern vehicles are equipped with advanced electronic systems, posing new challenges for mechanics and diagnosticians. Traditional diagnostic methods are proving insufficient in the face of the complex electronic architecture of modern cars.

Where did this come from?

In recent years, car manufacturers, including the Fiat Chrysler Automobiles (FCA) Group, have introduced a number of technologies to enhance security and protect against unauthorised access to vehicle systems.

One such solution is the Security Gateway (SGW) module, which has been fitted to new FCA vehicle models since 2018. The SGW effectively isolates most diagnostic requests, preventing non-original devices from accessing full diagnostic functions.

Why do they do it?

The reasons for introducing the SGW module are understandable. First and foremost, it is about security and protecting against unauthorised access to vehicle systems, which can have serious consequences.

Blocking access to full diagnostic functions prevents potential cyber-attacks and ensures that only authorised service centres have the ability to fully diagnose and service vehicles.

What makes this difficult?

While the aims are laudable, the introduction of SGW has also brought some complications for vehicle owners and independent mechanics. The lack of access to full diagnostic functions means that routine tasks, such as fault code clearing, can only be carried out at authorised service centres. This not only increases the cost of maintaining the vehicle, but also forces owners to make more frequent service visits, which can be inconvenient and time-consuming.

New solution – diagnostic adapter SDA2

In response to these challenges, the SDA2 diagnostic adapter was developed to offer a modern solution to SGW-related problems. The adaptor bypasses the limitations imposed by SGW, giving full access to all diagnostic functions. This allows vehicle owners to diagnose and fix faults themselves, without having to visit an authorised service centre.

In which models is the SGW module present?

The SGW module is fitted to most FCA Group vehicles manufactured from 2018 onwards. Here is a list of some of the models fitted with SGW:

– 2018: Chrysler Pacifica, Chrysler 300, Jeep Grand Cherokee, Jeep Wrangler, Jeep Renegade, Dodge Challenger, Dodge Charger, Dodge Durango, Dodge Journey, Ram 1500 (Classic Body Style), Ram 2500-5500 (Classic Body Style)

– 2019: All of the above models and additionally Jeep Cherokee, Ram 1500 (New Body Style)

– 2020 and later: Selected FCA Group models, including Alfa Romeo and Fiat.

What are the advantages of the SDA2 adapter?

SGW module bypass – allows full access to diagnostic functions blocked by SGW, allowing full vehicle diagnostics.

Compatibility with FCA models from 2018 onwards – works with SGW-equipped vehicles manufactured after 2018.

Safety and reliability – high build quality ensures a stable and secure connection.

Time saving – enables faster diagnostics without the need for original manufacturer equipment.

Cost effective – eliminates the need to purchase expensive original diagnostic equipment.

Enhanced functionality – allows access to a full range of diagnostic functions, including fault code clearing and ECU programming.

Ease of use – an easy-to-use adapter that requires no advanced technical knowledge.

Directions for use

Connect the adapter – locate the wiring harness leading to the SGW module and connect the SDA2 adapter to these wires.

Connect the diagnostic device – connect the diagnostic device to the OBD2 socket.

More on: OBD2 socket – what is it?

Start diagnostics – switch on the vehicle ignition and start the diagnostic device.

Perform operations – perform the desired diagnostic operations, such as clearing fault codes, etc.

Disconnect the adapter – when the diagnostics are complete, disconnect the SDA2 adapter from the wiring harness and connect the SGW.

Recommendations for use

We recommend that the SDA2 adapter is used mainly for diagnostic purposes. We do not recommend that the adapter is constantly plugged into the car’s harness, as this can lead to unnecessary problems. The adapter should only be plugged in when necessary.

The SDA2 diagnostic adapter in combination with the SDProg application is a revolutionary tool for every FCA Group vehicle owner. With this innovative solution, diagnostics become simple, fast and cost-effective. No more visits to the service centre just to clear fault codes – now everything can be done yourself, saving time and money.

The SDA2 adaptor gives vehicle owners full control over their car’s diagnostics and maintenance, resulting in longer vehicle life and greater satisfaction.
