Revolutionize Your Truck Control Unit Testing with WOYO PL014: The Ultimate One-Click HIL Diagnostic Tool
If you’ve ever spent way too long swapping modules in and out of a truck just to see if they work, you’ll get why the WOYO PL014 is such a game-changer. This little bench-top device lets you hook up any Volvo or Renault FCIOM (that’s the front-camera interface module) and, with a single press, cycle through eight key functions—lights, horn, wipers, the whole shebang—right there on your workbench. No more bouncing between your shop and the yard, no more “did it work this time?” letdowns. It’s all repeatable, safe, and efficient in ways that old-school road tests and DIY rigs simply can’t match.

Why Bench Testing FCIOMs Sucks… and How HIL Fixes It
Traditional bench setups mean you’re manually toggling signals, wiring up power supplies, and hoping your results line up with what the truck will do in real life. Or you haul the part back to the vehicle, bolt it on, start the engine—and pray. That costs time, money, and sometimes ends with you scratching your head over inconsistent results.
Hardware-in-the-Loop (HIL) testing changes the game. Instead of a real truck, you plug the FCIOM into a simulated environment that mimics sensors, cameras, lights—everything. You run as many scenarios as you like, all controlled from your bench. No risk of “truck won’t start,” no weather delays, and you can push your modules to extremes without worrying about damaging a $200,000 rig.


What the WOYO PL014 Brings to Your Bench
One-Click, Eight-Function Loop
Pop your FCIOM onto the test board, hit the switch, and watch it run through:
-
DRL (Daytime Running Lights)
-
Low Beam & High Beam
-
Fog Lights (FYI, Renault units skip this one)
-
City Horn & Regular Horn
-
Wipers (multi-speed)
-
Hazard Lights
Leave it in “loop” mode and it just keeps cycling—perfect for batch checks when you’ve got a stack of modules to verify.



Built Tough for the Shop Floor
Power’s no joke here: it needs a 24 V supply at over 10 A, so it can crank those lights and wipers just like a real truck would. The DB15 cable and clip-on connectors lock your module solidly in place. Plus, the rugged case survives being bumped around on a busy bench.
Who Needs This? Everybody.
-
Aftermarket Repair Shops: Instead of spending hours on a vehicle only to find one random function still quirky, you’ll know in minutes whether the repair stuck. That means faster turnaround, happier customers, and more billable jobs per day.
-
OEM Production Lines: Catch faulty FCIOMs before they ever go near a chassis. Batch-testing units off the line keeps returns to a minimum and quality ratings sky-high.
-
R&D & Software Teams: Pushed a new firmware update? Want to make sure that horn still honks when it’s supposed to? Run your regression tests right at the bench—no more waiting on field trials.
Benefits You’ll Actually Notice
-
Mad Repeatability: Hit “go” and it does the exact same test, every time. Compare that to juggling leads and switches by hand.
-
Zero Road Risk: Extreme temperatures, weird voltage spikes—run them all safely on your bench.
-
Cost & Time Savings: You’ll slice validation costs by up to 30 percent and speed through checks five times faster than crawling through real-world routes.
Bottom Line: Why the PL014 Beats Anything Else
Other HIL setups mean days of configuration, custom code, or expensive software licenses. The WOYO PL014 is plug-and-play for Volvo FH4/FM4 and Renault Euro 6 FCIOMs—no modeling, no fuss. And at its price point, you often cover the cost after just a handful of modules tested.
So, if you’re ready to stop guessing and start knowing, level up your diagnostics with the WOYO PL014. Your bench (and your bottom line) will thank you.
