Test and diagnose your PlayStation controller's rumble motors directly from your browser.
Traditional PlayStation controllers, like the DualShock 4, use an asymmetrical rumble system. The Left Motor contains a larger, heavier weight designed to simulate deep, powerful impacts like explosions or car crashes. The Right Motor contains a smaller, lighter weight designed for subtle feedback, like footsteps, rain, or UI interactions. Controller Diagnostic Lab allows you to isolate and test each motor independently to ensure both are functioning correctly at full intensity.
While standard rumble motors shake the entire controller chassis, the PS5 DualSense features groundbreaking Adaptive Triggers. These are independent, highly sophisticated gear mechanisms located directly inside the L2 and R2 buttons. They can dynamically change physical resistance, simulating the tension of pulling a bowstring or the kickback of a weapon. Our tool lets you test both the standard chassis rumble and apply custom resistance profiles (like "Weapon" or "Vibration") directly to your adaptive triggers.
