The Automotive evolution taking place, demands for increasingly technological diagnostic tools

Nicoletta Ferrini

From breakdowns to system errors: cars are changing, and with them also the types of breakdowns we can expect. As a result, techniques and tools needed not only to repair, but also to diagnose failures that could potentially compromise the smooth running of a vehicle, must change. The issue is closely intertwined with the relentless evolution that has been affecting the entire automotive sector for some time now.

It is estimated that by 2025, more than 70% of the vehicles on our roads could be natively connected cars, i.e. cars placed on the market with special on-board systems or equipped with "retrofit" solutions thanks to specific aftermarket components (source: Autopromotec Observatory elaboration based on Roland Berger information). In addition to these, hybrid and electric vehicles are taking larger market shares with each passing year, as are the many vehicles equipped with advanced electronic devices designed for active and passive safety, the so-called Adas (Advanced driver-assistance systems).

With vehicles that are increasingly sophisticated in terms of IT systems resembling hi-tech computers on wheels, the expert eye and capable hand of the professional aftermarket specialist may not always be enough. Several components that up until recently could simply be replaced, now must be accurately calibrated or reprogrammed after installation. If this does not happen, or is not done correctly, i.e. using an appropriate tool for diagnosis and programming, the vehicle may present the same error, generate a new one or simply suffer in terms of emissions, fuel consumption, performance and safety levels. Just to give a few examples: when replacing the windscreen on vehicles equipped with Adas, a static or dynamic calibration must also be carried out to ensure the correct functioning of the aforementioned safety systems; the warranty on some electric vehicles may be voided if a battery status check is not carried out using a diagnostic tool that measures the state of the battery and its residual life.

As a consequence the automotive diagnostics tools market is called upon to keep up with fast developing vehicles, offering advanced, user-friendly systems that include scanners and code readers for vehicle electronic control units, exhaust gas and battery status analysers, digital tire pressure gauges, failure monitoring devices and sensors and preventive diagnosis equipment for vehicle set up, engine or other components.

The global market for automotive diagnostics equipment is thriving with overall sales increasing every year. The year 2020 is expected to close with a global value of $41 billion, which is expected to reach as much as $53 billion by 2025. This was revealed by MarketsandMarkets following a recent industry analysis. According to the US research company, the driving forces behind such growth must be found in higher vehicle production and sales expected in the future, the subsequent increase in the number of car repair shops, the evolution of electronics and in-vehicle information technology, the tendency to integrate advanced digital functions into vehicles and the widespread connectivity of the automotive sector. However, this evolution is also driven by the growing attention that consumers and institutions are paying to aspects such as road safety and environmental impact, which could greatly benefit from careful diagnostics procedures.

The evolution of diagnostics tools must be viewed as a part of recent automotive history and is likely to play a key role in the near future. However, it also represents a great opportunity for the sector, starting with aftermarket operators who, having at their disposal advanced tools able to "read" vehicle data, can optimise business volumes, improve competitiveness and, last but certainly not least, offer customers a timely, quality service that is in step with the times, thus gaining more in terms of loyalty.



The Alientech range includes KESSV2, an OBD (on-board diagnostic) device for engine control unit and automatic transmission.
