Decoding Vehicle Diagnostics | KPIT
Recently, Henry had a wonderful road trip with his friends to San Diego. All went well until their car broke down on the way back home. With no roadside assistance, they were left stranded on the side of the interstate in 65+ degree Fahrenheit temperature. At that point of time, how badly Henry wished, he would have got an advance warning of his car's condition so that he could have got it repaired beforehand. After a long wait, they finally got help and managed to call for a mechanic to fix the fault. To their utter dismay, the mechanic had no clue what went wrong with the machine and struggled with the dense network of wires inside the car to diagnose the fault.

Now, only if they had a solution that could assist the mechanic to promptly identify the fault and fix the problem!

While OEMs are adding new features such as infotainment and connectivity to make travel more comfortable, are they also incorporating features to monitor and diagnose the health of the vehicles and help the end users to ensure smooth maintenance of their car, thereby enhancing their travel experience?
 
The automobile as we know, was not invented in a single day by a single inventor. It is a complex machine that has undergone over a century of evolution. Over the years, we have seen a constant stream of innovations and improvements in different systems of an automobile.

This evolution can be attributed to a number of factors such as increase in end users' expectations, safety standards, competition and changing business models, thereby significantly increasing the complexity of vehicle electronics and number of ECUs involved. This has in turn raised challenges for the after-sales and aftermarket service owners. Few major challenges are, vehicle recalls, increasing 'No Trouble Found (NTF)' cases, a higher ratio of repeat fault, nonproductive diagnostic time and vehicle down time.
Vehicle Diagnostics - Today
Vehicle diagnostics is an important tool for quickly and efficiently localizing and correcting faulty behavior of individual vehicle components. The development and introduction of new diagnostic concepts and diagnostic solutions offer significant potential to automotive OEMs and suppliers, for instance; over the past couple of years, major OEMs and Tier1s have moved to use Unified Diagnostic Services (UDS) as a standardized communication protocol for Off-Board Diagnostics. They have adopted data standards such as Open Diagnostic Exchange format (ODX) that helps in exchange and reuse of information within different departments and simplifies processes.
Vehicle Diagnostics - Future Trends
While we are talking of the present scenario, where we see different Auto OEMs at different maturity levels of Diagnostics adoption, we can strongly predict that the future of Vehicle Diagnostics will be 'CONNECTIVITY'. This would ensure that, a vehicle is not only diagnosed in the dealership outlet but also constantly monitored and optimized by latest ECU software updates. Furthermore, as the vehicle becomes more software driven, its features can be enhanced over its lifecycle (e.g. Over the Air (OTA) updates), and even features like autonomous driving can be added to a vehicle after production. By combining Diagnostics and Connectivity, OEMs will be able to offer additional services to their customers. If customers agree to share their automotive data, companies will be able to aggregate the data and can provide advanced services such as Predictive Maintenance to them.

Also upcoming technologies like Cloud & Mobile based Diagnostics Solutions are expected to bring biggest improvement in areas such as Early Field Warnings. This feature would ensure that any issue in the vehicle can be recognized much earlier in the lifecycle, thereby, resulting in reduction in the operational cost of the vehicle & enhanced customer satisfaction. Big Data & Analytics will be the key factors for the success of Diagnostics in the future.
Here at KPIT, we understand the key trends & challenges related to Vehicle Diagnostics and can help you address them using our deep domain understanding and proven diagnostic products/solutions which are based on KPIT's Diagnostic & Connectivity Platform. Some of our key offerings in this domain are:
