If you are about to pull the rear wheels off a modern car for a pad swap, the best OBD2 scanner for electronic parking brake work is simply the one that can actually talk to your car’s EPB module — and for most home mechanics that is the FOXWELL NT614 Elite. It is the cheapest tool I trust to do both halves of a rear brake job: retract the caliper motors so the old pads come out, and bleed the ABS afterwards if you opened a line. But before you spend anything, read the next section. On a lot of cars — most GM trucks and a good number of Fords included — the service mode you need is built into the vehicle and costs nothing. I learned that the expensive way, with a scan tool already in the cart.

Before you buy: your EPB type decides everything
No roundup I read answers the one question that decides whether you need to buy anything. There are two common electronic parking brake architectures, and they behave completely differently on the bench.
Motor-on-caliper. A small geared motor bolts to the back of each rear caliper and drives the piston out on a screw. Audi and VW have used this since 2004; BMW, Porsche, most Toyota and Lexus, Honda and Acura, and the Jeep and Chrysler small platforms all use variations. You cannot wind these pistons back with a cube tool, and you cannot shove them back with a C-clamp. The motor has to walk the screw back first, and that command lives in the car’s module.
Cable-puller. One motor under the body — TRW, SKF or Bosch hardware — pulls conventional parking brake cables. The caliper itself is an ordinary hydraulic piston that compresses normally. GM, Ford, Jaguar, Subaru and several others use this. Here you only need the cable slack released, and that is where the free option lives.
The two makes where you probably don’t need an EPB retract tool
GM publishes a no-scan-tool release: chock the drive wheels, ignition ON with the engine off, transmission in Park, hold the brake pedal down for the whole procedure, then press and hold the EPB switch about five seconds until the PARK BRAKE lamp flashes. Release the switch, immediately press and release it again, and the cable tension is gone. There is even a no-tool calibration that involves pulling and reseating the EPB module fuse.
Ford has a driver’s-seat sequence too. On a Fusion from 2013 on, and on the same pattern across much of the range: ignition ON, press the accelerator to the floor, move the EPB switch to release, and while still holding both, cycle the ignition off and back on within five seconds. The yellow EPB light comes on and the message centre says maintenance mode. You exit with the switch in the apply position.
One of the articles ranking for this keyword asks whether its scanner works on a 2022 Ford F-150 and never answers. For that truck, the honest answer is that you probably don’t need a scanner at all.
The best OBD2 scanner for electronic parking brake service: 5 picks
1. FOXWELL NT614 Elite — best overall
A four-system handheld — engine, ABS, SRS and transmission — with five service functions, EPB service mode and ABS auto-bleed among them.
Why I rate it:
- It covers both halves of a rear brake job. EPB retract gets the pads out; ABS bleeding matters if you crack a line or a caliper has air upstream. Most tools near this price do one or neither.
- It reads and clears ABS module codes. On most EPB systems the ABS module is what powers and grounds the caliper motors, so a tool that cannot see that module has no route to command it.
- Free lifetime Wi-Fi updates with no account registration and no subscription.
- Menus are make-specific rather than generic, so EPB appears where the carmaker filed it instead of behind a one-size-fits-all “brake reset”.
Honest drawbacks: EPB coverage is per-make, not universal — run your exact make and year through Foxwell’s vehicle list before you buy. And the NT604 and NT614 Elite listings look almost identical; only the NT614 Elite carries the five resets, and people buy the wrong one constantly.
Buy it if you are doing your own rear pads on a European or Asian car with motor-on-caliper EPB. Check the current price.
2. TOPDON AD500 — best budget EPB reset scan tool
Six resets — oil, steering angle, throttle, TPMS, battery management and EPB — on a 5-inch touchscreen with lifetime free Wi-Fi updates.
Why I rate it:
- It is the cheapest tool here that lists EPB as a named service function rather than a vague “brake reset”, which on budget tools often means nothing more than clearing a pad-wear light.
- The BMS reset is useful alongside it: you want that after a battery swap, and EPB behaviour depends on battery health.
Honest drawbacks: no ABS bleeding, so if you open a hydraulic line you still need a second tool. Reset coverage thins out on older European platforms.
Buy it if pads on a mainstream car are the only EPB job you expect to do. Check the current price.
3. Autel MaxiCOM MK808S — best premium
A full-system bidirectional Android tablet with 28-plus service functions including EPB, plus active tests and FCA AutoAuth.
Why I rate it:
- Bidirectional active tests let you command each caliper motor and watch it respond. That is how you separate a seized caliper from a dead motor instead of guessing — a sticking caliper shows up as a slow motor response, which is exactly the clamp-time fault that trips EPB performance codes.
- Full-system scan across every module, not just the big four.
- FCA AutoAuth included, which you need for Chrysler, Jeep, Dodge and Ram secure gateway access.
Honest drawbacks: it is a lot of money for a pad job, typically in the mid-hundreds, and after the first year updates become a paid subscription. Autel also sells near-identical hardware as the MK808S, MX808S and MK808Z depending on region and bundle, so read the listing title carefully.
Buy it if you service several makes, or you are diagnosing an EPB fault rather than just retracting pistons. Check the current price.
4. LAUNCH CRP129X — widest reset list
Twelve reset functions including EPB, steering angle, oil, TPMS, throttle, BMS, DPF, injector coding and ABS bleeding, on top of four-system diagnostics.
Why I rate it: the longest reset list at this price, and it includes both EPB and ABS bleeding rather than forcing a choice. AutoVIN saves menu-diving, and Wi-Fi updates are free.
Honest drawbacks: the LAUNCH naming is a mess — CRP123X, CRP129X, CRP129i and CRP129E all sit within about sixty dollars of each other with different reset lists, and one of the sites ranking for this keyword recommends a cheaper sibling without checking the list. Buy on the printed reset list, not the family name. Owners also consistently report slow boot times and sluggish menus.
Buy it if you want one mid-priced tool that does nearly every service reset. Check the current price.
5. Innova 5610 — best for US domestics
A bidirectional handheld built around US-market fitment, with EPB retract and live data for engine, ABS, SRS and transmission.
Why I rate it: Innova’s coverage is written for domestic platforms rather than translated from European menus, which shows on GM and Ford trucks. It sends a real EPB retract command on supported vehicles, and its four-system live data graphs rather than snapshots.
Honest drawbacks: it is not universal, and Innova’s own guidance is to run your vehicle through their coverage checker before assuming EPB retract is supported — worth doing, because the answer is genuinely no on some models. It also costs more than the Foxwell while offering fewer resets.
Buy it if you own GM, Ford or Chrysler vehicles and want one tool for all of them. Check the current price.
What actually matters when choosing an EPB retract tool
Your EPB architecture, first. Motor-on-caliper means you need a commanded retract, full stop. Cable-puller may mean you need nothing but the sequence above. Find out which you have before you spend.
The function-name trap. “EPB reset”, “EPB service mode” (sometimes “replace mode”) and “EPB calibration” are three different routines. Reset clears a pad-wear adaptation. Service mode walks the motors back so the pads come out. Calibration re-learns clamp force afterwards. A spec sheet that just says “EPB” may only be offering the first one, which is useless to you on a pad job.
It has to reach the ABS module. On most systems the ABS module drives the caliper motors. One well-known review of a popular app dongle failed EPB unlock outright because it could not establish ABS module communication — a generic engine-code reader will never do this job.
Coverage is per-make, not per-tool. Every tool here supports EPB on some vehicles and not others. Check the manufacturer’s coverage list for your make, model and year. This is the single most common source of one-star reviews on all five.
Keep a charger on the car. Ross-Tech’s guidance for VW and Audi EPB is blunt: the module is very sensitive to low voltage, and a charger should stay connected for the entire rear brake job. On cars with a boot-mounted battery, connect at the designated charging posts so the battery management module still sees the current. GM’s own documentation says that with insufficient electrical power the EPB can be neither applied nor released. A dying battery mid-procedure is how a simple pad swap turns into a tow.
FAQ
Do I need a scan tool to change rear brake pads with an electronic parking brake?
On motor-on-caliper systems, yes — something has to command the motors back. On GM and Ford cable-puller systems, usually no: both publish a driver’s-seat sequence that releases cable tension without a tool.
Can you manually retract an electronic parking brake?
Sometimes. Some calipers let you unbolt the motor housing and turn the drive screw back with a Torx or Allen bit, then press the piston in. Owners do this on Lexus and Porsche calipers when a procedure stalls. It works, but you risk the O-ring and the gear teeth, and trade bodies warn that removing motors or jumping connectors can set codes or damage the unit. Treat it as a rescue, not a method.
What happens if you don’t put the EPB in service mode?
Two things. You fight a piston that will not move, and if the motor is commanded while the caliper is apart the piston comes out hard and fast — fast enough to hurt your fingers and to damage itself if it leaves the bore. You can also end up with the module holding a clamp state that no longer matches reality.
Will a cheap OBD2 scanner reset the parking brake?
A $25 code reader will not. It talks to the engine module over generic OBD2 and nothing else. The cheapest tools that do real EPB work sit around the hundred-dollar mark, and even then only on supported makes.
Why won’t my electronic parking brake come out of service mode?
Usually because the procedure was interrupted. The EPB module has no sensor telling it that pads were replaced; it only tracks what it last commanded. One Porsche Macan owner who paused mid-job to find a lug adapter then got “parking brake not in assembly position” on both sides and needed repeated attempts, an ignition cycle and a code clear before the exit command took. Finish the routine in one pass, with the tool still plugged in.
Verdict
For most people doing their own rear pads, the FOXWELL NT614 Elite is the right buy: it retracts the calipers, bleeds the ABS, reads the module that actually runs the system, and updates free forever. On a tight budget the TOPDON AD500 covers the pad job for about half as much, as long as you accept no ABS bleeding. And if you drive a GM or a Ford, try the free sequence first — you may not need either.
