Best OBD2 Scanners with Active Oil Reset and EPB Services: Which One Should You Buy?
A simple oil change used to be one of the easiest maintenance jobs for any vehicle owner. Today, many modern cars can require electronic service resets, battery registration, and even special procedures just to complete routine maintenance correctly.
The problem? Many basic OBD2 scanners can read engine fault codes but cannot perform the active service functions that modern vehicles require.
If your vehicle has an electronic parking brake (EPB), replacing brake pads or performing maintenance without the correct scanner can become frustrating, time-consuming, and potentially expensive.
The right OBD2 scanner with active oil reset and EPB service functions can help you:
- reset maintenance reminders after servicing
- retract electronic parking brakes safely
- perform brake service procedures
- diagnose vehicle systems beyond engine faults
- reduce unnecessary workshop visits
But choosing the right tool is not as simple as buying the most expensive scanner available.
Some scanners offer impressive feature lists but provide limited real-world support. Others deliver excellent value for home mechanics, enthusiasts, and small automotive businesses.
This guide compares the best options, explains what these functions actually do, discusses pricing, highlights mistakes to avoid, and helps you choose a scanner that matches your vehicle and budget.
What Is an OBD2 Scanner with Active Service Functions?
An OBD2 scanner is a diagnostic device that communicates with your vehicle’s computer systems.
Traditional basic scanners mainly read and clear fault codes.
Advanced scanners can perform active service functions, which means they can send commands to vehicle modules instead of only reading information.
Examples include:
- oil service reset
- electronic parking brake service mode
- battery registration
- steering angle calibration
- throttle adaptation
- diesel particulate filter regeneration
- ABS bleeding procedures
These features are especially useful because modern vehicles rely heavily on electronic control systems.
A scanner with active service capability acts more like a maintenance assistant rather than just a fault-code reader.
Why Oil Reset and EPB Services Matter
Many vehicle owners assume an oil change only requires replacing oil and a filter.
However, modern vehicles often track maintenance electronically.
After servicing, the vehicle may still display:
- service due warnings
- maintenance reminders
- incorrect service intervals
An oil reset function allows the owner or technician to update the vehicle’s maintenance information.
Without resetting the system:
- warning messages may remain active
- service records may become inaccurate
- future maintenance tracking may be affected
What Is an Oil Reset Function?
An oil reset function tells the vehicle’s computer that scheduled maintenance has been completed.
Depending on the vehicle, it may reset:
- oil life percentage
- service countdown
- maintenance reminder lights
- inspection intervals
For example:
A driver completes an oil change at home.
The vehicle still displays:
“Oil Service Required”
An OBD2 scanner with oil reset capability can communicate with the vehicle and update the maintenance system.
What Is EPB Service?
EPB stands for Electronic Parking Brake.
Unlike traditional handbrakes that use cables and mechanical levers, many modern vehicles use electric motors controlled by electronic modules.
These systems are common in:
- European vehicles
- newer SUVs
- luxury cars
- vehicles with advanced safety systems
During brake pad replacement, the EPB system often needs to enter service mode.
This allows the brake actuator to retract safely.
Why EPB Service Requires the Right Scanner
Trying to replace rear brake pads on an EPB-equipped vehicle without proper electronic service access can cause problems.
Possible issues include:
- damaged brake actuator motors
- incorrect brake operation
- warning lights
- failed calibration
A suitable scanner allows technicians or experienced DIY users to:
- Put the electronic brake system into maintenance mode.
- Complete brake work safely.
- Restore normal operation.
- Confirm that no faults remain.
This is one reason advanced scanners have become popular among DIY mechanics.

How to Choose the Right OBD2 Scanner for Oil Reset and EPB Service
Buying an advanced OBD2 scanner is different from buying a simple code reader.
A basic scanner is mainly designed to answer:
“Why is my warning light on?”
An advanced service scanner answers:
“What can I do about it?”
When comparing scanners with active oil reset and EPB capabilities, focus on the functions you actually need rather than impressive feature lists.
The most important buying factors are:
- vehicle compatibility
- supported service functions
- software reliability
- update costs
- ease of use
- long-term value
A scanner that performs perfectly on one vehicle may be disappointing on another.
Step 1: Check Your Vehicle Before Buying
The first mistake many buyers make is purchasing a scanner before checking compatibility.
A scanner may advertise:
“Supports 10,000+ vehicles”
but that does not mean every function works on every model.
Always verify:
- make and model
- production year
- engine type
- transmission type
- required service functions
For example:
A scanner might support oil reset on a 2018 Ford Focus but only offer basic diagnostics on a 2018 Mercedes-Benz.
The difference is not the scanner’s quality.
It is the manufacturer’s communication requirements.
Step 2: Decide How Advanced You Need to Go
Your ideal scanner depends on your experience level.
Beginner Vehicle Owners
Most beginners need:
- oil reset
- EPB service
- fault code reading
- maintenance reminders
- simple repair information
A mid-range scanner is usually the best choice.
It provides useful functions without unnecessary complexity.
Experienced DIY Mechanics
Experienced users often want:
- bidirectional controls

- ABS functions
- battery registration
- adaptation procedures
A more advanced scanner becomes a practical investment.
Professional Technicians
Professionals require:
- fast diagnostics
- broad vehicle coverage
- reliable updates
- technical support
- advanced programming functions
Downtime costs money, so speed and accuracy become more important than purchase price.
Important Service Functions Beyond Oil Reset and EPB
Oil reset and EPB service are popular features, but they are only part of what modern vehicles require.
A better scanner may include additional maintenance functions.
Battery Registration Service
Many newer vehicles require battery registration after replacement.
Why?
The vehicle’s charging system monitors battery condition.
When a new battery is installed, the computer may need to know:
- battery type
- capacity
- replacement status
Without registration, some vehicles may charge incorrectly.
A scanner with battery service capability can simplify this process.
ABS Service and Brake Bleeding
Brake systems have become increasingly electronic.
Advanced scanners may assist with:

- hydraulic system testing
This is especially useful after brake repairs.
DPF Regeneration for Diesel Vehicles
Diesel owners may benefit from scanners supporting diesel particulate filter functions.
A DPF service function can help with:
- monitoring filter condition
- initiating regeneration procedures
- diagnosing related faults
However, regeneration should only be performed when appropriate.
A scanner does not replace proper mechanical diagnosis.
Steering Angle Calibration
Some vehicles require steering angle calibration after:
- wheel alignment
- suspension repairs
- steering component replacement
A scanner with this function can help restore correct electronic stability system operation.
Throttle Adaptation
Electronic throttle systems may require adaptation after certain repairs or battery disconnections.
A suitable scanner can help perform this procedure.
Active Test Functions: The Feature That Separates Basic From Advanced Scanners
One of the most valuable upgrades in a diagnostic tool is active testing.
Active tests allow the scanner to command vehicle components.
Examples include:
- turning relays on and off
- activating pumps
- testing fans
- controlling valves
This helps technicians confirm whether components actually work.
Instead of only seeing:
“Possible fuel pump problem”
a technician can test the fuel pump operation directly.
This saves time and reduces guesswork.
OBD2 Scanner Software: The Hidden Factor Many Buyers Ignore
Many buyers compare hardware specifications but overlook software quality.
Diagnostic software determines:
- how many vehicles are supported
- how accurate information is
- how often new models are added
- how easy the scanner is to use
A scanner with excellent hardware but poor software can become frustrating.
Before buying, check:
- update frequency
- subscription pricing
- update duration
- customer support reputation
Subscription Costs: The Real Price of Ownership
The purchase price is only part of the total cost.
Some premium scanners require:
- annual updates
- cloud services
- technical support subscriptions
Example:
A scanner may cost £500 initially but require £150 per year for updates.
Over several years, ownership cost increases significantly.
A cheaper scanner with free updates may provide better long-term value for casual users.
OBD2 Scanner Comparison: Personal vs Professional Use
