OBD2 Scanners for EPB Reset: What You Actually Need for Electronic Parking Brakes
Published: March 8, 2026 · Last updated: June 1, 2026
If your car has an electronic parking brake, you can’t just wind the rear calipers back by hand to change the brake pads. The EPB motor holds the pistons electronically, and you need a scanner to put the system into service mode so it retracts them safely. Try to force it without that, and you risk damaging the caliper or the motor.
Here’s the reassuring part before you start shopping: EPB reset is not a rare or premium feature, almost any full-system or service-reset scanner from a normal brand handles it. So this guide is less about hunting for one special tool and more about understanding what the reset does, and knowing the handful of cases where a cheap tool still falls short on a specific car.

The honest truth about EPB reset is that it’s not a feature worth overpaying for. It’s one of the most common service functions out there, so almost any full-system or service-reset scanner from a normal brand, Launch, Kingbolen, Topdon, Mucar, Thinkcar, Youcanic, will do it. The one thing it rules out is a basic engine-only code reader, because EPB lives in the brake module and a cheap reader can’t reach it. Beyond that, pick the scanner that fits the rest of your work and EPB comes included.
That said, “widely supported” isn’t “universally supported,” and I learned that the hard way. On a Toyota Proace City 2020, none of the budget winners on this list could complete the EPB reset, and I only opened it with the Autel IM608. That’s not a reason to buy a $3,000 tool for brake pads, it’s a reason to confirm your specific car is covered before you buy anything. Most cars are fine on a cheap tool. A few aren’t, and you only find out on the car.
So if you just want a reliable, affordable tool that handles EPB along with everything else, the XTool A30M is my value pick at around $140, full-system, free updates, and one of my favourite tools regardless of price. If you want standalone with no phone, the Vdiagtool D200 does full-system EPB resets as a handheld around $150. And if you already have an ELM327 adapter, try the Carista app first, it may already cover your car for nothing extra.

Why can't I just push the caliper pistons back by hand?
Because the EPB motor is mechanically holding them. On a traditional handbrake you can wind the piston back with a tool, but an electronic parking brake has to electronically release and retract first. Skipping the service mode step is how people damage calipers and motors on EPB-equipped cars.
Can I use a phone app like Carista for EPB?
On some cars, yes. If you already own an ELM327 adapter, an app like Carista supports EPB unlock on a range of brands, which makes it the cheapest route if your car is covered. Check the app's supported-car list for your model first, since coverage is the deciding factor.
Will a cheap scanner do EPB on my car?
Usually yes, but not always. The function is widely supported, but coverage on a specific make and model can vary, and I've hit cars where the budget winners couldn't complete the reset and only a pro tool could. So confirm EPB support for your exact car before buying, rather than assuming "has EPB reset" means your model.
Do I need a special scanner just for EPB?
No. EPB service mode is one of the most common service functions, and almost any full-system or service-reset scanner from a reputable brand, Launch, Kingbolen, Topdon, Mucar, Thinkcar, Youcanic and others, does it. You don't need a dedicated or expensive tool. What you do need is one that actually accesses the ABS/brake module, which rules out basic engine-only code readers.
What is an EPB reset and why do I need one?
An electronic parking brake holds the rear brakes with an electric motor instead of a cable. Before you change the rear pads, the scanner puts the EPB into service mode, which retracts the pistons so you can open the calipers. Without it you can't safely compress the pistons, and forcing them risks damaging the caliper or the EPB motor.
