LV124 / LV148 Fully automated testing

Structured automotive testing.
From first test to final report.

WKS Informatik builds fully automated testing systems for LV124 and LV148 — so your engineers spend less time managing setups and more time shipping validated products.

LV124 / LV148 testing has never been more complex.

More ECUs, more variants, more test cases — and most teams are still managing it manually. Here’s what that looks like in practice:

Manual / half-automated setups

What most labs deal with today

  • ECU-specific setups that need rebuilding each time
  • Manual supervision around the clock
  • Covers only ~1/3 of the LV124 norm
  • No reproducibility — results vary run to run
  • No support for CAN, LIN, or Ethernet
  • High cost, high risk of human error
With RTStand

What structured testing looks like

  • Generic design — reusable across all your ECUs
  • Runs unattended — nights, weekends, no supervision
  • Full LV124 / LV148 norm coverage
  • 100% reproducible results, automated reports
  • Native CAN, LIN, Ethernet, GMSL support
  • 75% faster test cycles — 24/7 operation

Three ways WKS structures your testing.

Whether you need the hardware, the lab time, or the expertise — we cover the full stack.

We have been using the RTStand LV124 / LV148 system from WKS Informatik for several years and are very satisfied with its high reliability and the fast, straightforward support. Regular maintenance and calibrations ensure that the system is always ready for use, and the personalized service significantly contributes to our satisfaction

SMR Automotive

The RTStand LV124 / LV148 system from WKS Informatik has not only increased our testing efficiency but also improved the workflow in our laboratory. Collaborating with WKS Informatik allowed us to implement custom adjustments, and we consistently benefit from prompt technical support. This efficiency and support have enabled us to effectively overcome the challenges of our dynamic development processes

Bühler Motor

The concept for automated testing of the LV124 prompted us to purchase a test system. The tests can now actually be performed and analyzed automatically. This saves time and resources. The support is also impeccable, and downtimes are minimized through a fast response time.

Leading automotive lighting supplier

We have reduced the overall testing time to a half compared to the previous manual testing and currently save 150.000 EUR for the LV124 testing of every several new software releases of our product

French automotive supplier

“One crucial advantage of your test system, besides timing and other benefits, is reproducibility! With a fully automated test run, there is no room for slight variations in the test runs anymore.”

Top 5 automotive supplier worldwide

This innovative modular concept, which gives us the opportunity to monitor a high number of pins in parallel, with a high resolution of up to 10us, as required in the LV124, allows us to make a deeper analysis of our products and especially find sporadic errors earlier in the development phase.
