Fully automated LV124 / LV148 testing solutions for OEMs and Tier-1 suppliers. We help reduce complexity and enable scalable automotive validation.

Automotive testing is becoming increasingly complex – but it doesn’t have to be. WKS Informatik specializes in automated LV124 / LV148 testing for OEMs, Tier-1 suppliers and test labs. We support our customers in transitioning from manual, fragmented test setups to scalable and reproducible validation environments. With solutions like RTStand, complex test sequences can be executed automatically, reducing manual effort and increasing consistency. Our focus is clear:
Making automotive testing reliable, scalable and manageable – even in highly complex environments. Based in Germany, we support customers worldwide.

TestingEnables — Part 4: Reliability

SMR Automotive has been running for years and across multiple product generations of mirror systems with integrated cameras.

Their words: "We 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."

Every update we release goes to every system. Not an upgrade — an update. Norm library growing (50+ current SP). Full stack maintained: tools, sequences, firmware, drivers, OS.

Custom test benches age fast. RTStand doesn't — because it's a platform, not a project.

, , . Three competing standards? No.

ISO 16750 is the international baseline, with general, middle-ground values.

LV 124 is a family of OEM norms — VW 80000, BMW GS95024, MBN 10567, covering passenger cars, trucks, buses, motorcycles and agricultural machines — that sharpen the same test types: tighter variations, or entirely different profiles. LV 148 covers 48V networks.

Test to the OEM norm and you have typically covered the corresponding ISO tests. The reverse isn't guaranteed.

That's why a test system has to carry all of them. covers 50+.

— Part 3: Reproducibility

Sunday's Bahrain GP in Sepang started 53 minutes late. A software issue made several cars lose power on the formation lap.
The FIA called the cause an unprecedented combination of conditions, in a season with almost no wet running.

Just because it ran once doesn't mean it always runs. And it can still go wrong once it's out on the road.

One of our customers validates safety-critical ECUs across dozens of variants.
With RTStand, run 1,000 is literally the same test as run 1. And when something fails, you can find out why — because nothing else changed.

Manual testing gives you effort. Automated, reproducible testing gives you certainty.

RTStand LV124 / LV148 2026SP1 is official out now!

And so is the official release of the 90A / 5kW system!
A new power class, built on the same platform and toolchain as every other RTStand variant — not a separate development from scratch.

The norm library now covers 50+ norms and specifications, including BMW GS95024-2-1 2026, JAC QJQ36342, and Ducati's own DMH 34-03.001 — passenger car, motorcycle, trucks, machines and everything in between.

Reporting got more precise too: logging rate shown right in the PDF footer, and report pages auto-exported as individual JPGs.

That's the advantage of a platform over a one-off build: a new power class or a new norm doesn't mean starting over. It means extending what's already there.

— Part 2: Speed

A Tier-1 customer told me recently: their module test took five weeks before automation. Now, five days.

Sounds like efficiency. It isn't, not really. Their own customers — premium OEMs — said: “Cool, now you have time for more test cycles. Please use it.”

The same module doesn't get tested once anymore — it gets tested multiple times. A completely different confidence level at the end.

Time saved isn't the outcome of automation. The outcome is what happens with the time that didn't exist before.

— Part 1: Depth

Some faults don't show up in the first hour, the first night, or the first hundred cycles.

Finding them takes running the same sequence for days — which only works because the test is fast enough to free up that time, and reproducible enough to trust the result. But that just gets you the opportunity to look. Depth is what you actually see.

monitors the entire DUT at once — supply, CAN, LIN, Ethernet, all time-synchronized, around the clock. Not one signal at a time. Everything, together, for as long as it takes.

9 of 10 vehicle quality categories improved this year. Infotainment didn't.

J.D. Power's 2026 Multimedia Quality and Satisfaction Study: 78,514 new-vehicle buyers, surveyed after 90 days. Infotainment now accounts for 25% of all reported problems — the largest single category, and the only one that got worse. The five most frequently reported problems across all new vehicles are all infotainment-related.

A few years ago, a company building interior components — displays included — laughed at us for insisting they needed thorough testing. His argument: short glitches don't matter, not safety-relevant, better to stick to the old manual way.

Running a test a few times manually and calling it validated was never really enough. It's certainly not enough now. What manual spot-checks structurally cannot deliver — reproducibility and depth, run after run — is exactly what a fully automated system like is built for.

One platform. Every application.

Passenger cars. Motorcycles. Trucks. Agricultural machinery.
12V · 16V · 24V · 48V.

RTStand LV124 / LV148 doesn't get redesigned when the requirements change — it gets a new norm profile. Same system, from classic 12V boards to manufacturer-specific specs like 's DMH 34-03.001, to the 16V world of MBN 50569.

50+ norms and counting.

RTStand Testing

New arrival in the WKS lab 🚀
This is our largest and most powerful system yet — and it's on its way to the customer.
For years, one question kept coming back to us:
"Can you also test high-current DUTs? Traction inverters, high-power actuators, EV powertrain components?"
The honest answer used to be: not fully automated, no.
That answer just changed.
Meet the RTStand F8-90 — fully automated / testing up to 90 A and 5kW. Same speed. Same depth. Same 100% reproducibility as every RTStand we've delivered over the last decade. Just at a much higher current level.
The whole class of current-intensive automotive ECUs is now within reach!
