Saab and the dawn of fault code readers
It all began in the 1980s when car manufacturers like Saab started implementing limited computer control in their vehicles. These early electronic systems required diagnostic tools to identify and resolve problems. However, these primitive fault code readers could do no more than provide simple flashing patterns for various fault codes.
The introduction of OBD systems
Over time, these systems were improved and standardized, resulting in the introduction of OBD (On-Board Diagnostics). The first version, OBD-I, was launched in the early 1990s and paved the way for more advanced diagnostic functions. OBD-II soon followed, becoming universal for cars in the USA from 1996 onwards and subsequently globally accepted. It allowed for more detailed monitoring and troubleshooting, which revolutionized the automotive industry.
The digital revolution of diagnostics
Advances in technology mean that modern fault code readers can now read and clear fault codes with a simple press of a button, where the KONNWEI KW906 offers impressive capabilities. This Bluetooth 5.0 OBD2 code reader simply connects to a smartphone or tablet, allowing car owners to manage many of their car problems themselves.
Hybrid and electric cars
With the transition to hybrid and electric cars, the demands on fault code readers' capabilities have increased. Modern vehicles include more sophisticated electronics, which requires fault code readers to evolve as well. Tools like the Vgate iCar2 Bluetooth OBD2 Code Reader therefore support all OBDII protocols and are adapted for today's modern vehicles, including hybrids.

Frequently asked questions
What is a fault code reader?
A fault code reader is a device used to diagnose problems in a vehicle by reading fault codes stored by the car's computer system.
How do fault code readers work?
The fault code reader connects to the car's OBD-II port, which is found in almost all modern vehicles. It communicates with the car's computer to retrieve information about any faults and system status.
What role did Saab play in the development of fault code readers?
Saab was an early adopter of integrating advanced diagnostics into their cars in the 1980s, laying the groundwork for the development of modern fault code readers and real-time diagnostics.
Can I use a fault code reader on all types of cars?
Most modern fault code readers are designed to work with OBD-II compliant cars, which includes most vehicles manufactured after 1996. Older cars may require specific readers.
Do I need any special training to use a fault code reader?
No, most fault code readers are user-friendly and come with instructions. However, a basic understanding of the car's systems can be helpful in interpreting the results.
What types of fault codes can be read by a fault code reader?
Fault code readers can identify various types of problems, including engine malfunctions, emission system issues, and sensors not functioning correctly.
How can I interpret fault codes?
Fault code readers display codes in the form of alphanumeric strings. There are resources, such as manuals and online databases, where you can look up what each code means.
Can a fault code reader help me save money on repairs?
Yes, by quickly identifying the problem, a fault code reader can help car owners avoid costly errors and make informed decisions about necessary repairs.
Are fault code readers as effective on hybrid cars as on traditional petrol cars?
Yes, fault code readers are equally effective on hybrid cars. These vehicles have advanced systems that can also be diagnosed with the right equipment.
