What is ALLDATA: A Comprehensive Guide for Repair Shops

Table of Contents

Shop owners and technicians face significant challenges keeping up with the technical complexities of modern vehicles. With increasingly sophisticated systems like ADAS becoming standard, accessing accurate repair information is essential for thorough repairs and happy clients. 

Many shops struggle to locate specific repair procedures, often relying on outdated manuals or spending excessive time searching for information that may not be reliable. This creates workflow bottlenecks, reduces profitability, and increases liability risks.

In this guide, we'll discuss everything you need to know about ALLDATA—one of the industry's leading repair information systems—and explain how it can be invaluable for shop owners and technicians. 

What is ALLDATA?

ALLDATA is the industry's leading choice for unedited OEM (Original Equipment Manufacturer) automotive repair information. Founded in 1986 and acquired by AutoZone in 1996, ALLDATA provides technicians with factory-direct repair information for over 44,000 engine-specific vehicles—covering approximately 95% of all vehicles on North American roads today.

Unlike crowdsourced information or generic repair manuals, ALLDATA delivers manufacturer-specific repair procedures, diagrams, specifications, and technical service bulletins in their original format. This ensures repairs meet OEM standards, reducing liability and ensuring quality work.

Popular ALLDATA products

ALLDATA offers several products designed for different segments of the automotive repair industry:

Key features that solve shop challenges

ALLDATA has multiple features and products that can solve critical challenges for shops who are trying to offer ADAS calibrations. Let’s look at the key features you can benefit from. 

OEM-accurate information

One of the biggest issues shops face is finding reliable repair information that meets manufacturer standards. ALLDATA addresses this by providing unedited repair information directly from a large number of vehicle manufacturers.

This includes the full spectrum of repair information from mechanical specifications to complex procedures for advanced safety systems.

ADAS Quick Reference

Even as ADAS features become standard, many technicians struggle to identify which components require calibration after repairs. ALLDATA's ADAS Quick Reference feature provides one-click access to vehicle-specific ADAS information.

The tool helps shops:

  • Quickly identify ADAS components by name and locate them on the vehicle. 
  • Determine if calibration is needed after specific repairs.
  • Access removal and replacement procedures.

This feature is particularly valuable because ADAS calibration requirements vary widely between manufacturers. 

Interactive color wiring diagrams

Electrical diagnostics often consume excessive time as technicians trace complex wiring systems. ALLDATA's interactive color wiring diagrams allow technicians to:

  • View complete electrical systems with color-coded wires.
  • Zoom in on specific circuits.
  • Click on components to see additional information.
  • Print selected sections of diagrams.
  • Access component locations and connector views.

These interactive diagrams significantly reduce diagnostic time, especially for complex electrical issues.

How shops benefit from using ALLDATA

Shops may benefit from using ALLDATA in three key ways: increased efficiency, reduced liability, and more revenue. 

Increased efficiency and productivity

By providing immediate access to accurate repair information, ALLDATA helps shops:

  • Reduce diagnostic time.
  • Eliminate time spent searching for repair procedures.
  • Decrease comebacks by ensuring repairs meet OEM standards.

Reduced liability

ALLDATA helps limit liability by:

  • Providing manufacturer-required procedures for every repair.
  • Documenting that repairs followed OEM guidelines.
  • Ensuring ADAS and other safety systems function correctly after repairs.
  • Creating a record of all work performed according to standards.

New revenue opportunities

With comprehensive repair information, shops can identify new revenue opportunities with existing customers. This can create additional revenue in the following ways: 

  • Take on more complex repairs that would otherwise be referred elsewhere.
  • Perform ADAS calibrations in-house rather than subletting.
  • Reduce parts returns by ordering the correct components initially.

How ALLDATA compares to alternatives

The automotive repair information market includes several options beyond ALLDATA. 

Dealer-specific systems provide information for only one manufacturer, which can be helpful for specialized shops but often requires separate subscriptions for each make you want to service. This approach typically costs more for multi-brand shops. 

Some aftermarket information systems vary in coverage depth and accuracy. Many edit or consolidate OEM information to create a more standardized format across different manufacturers, which can simplify navigation but may lose important details in the process. 

When comparing these options, it's important to consider your shop's specific needs. 

ALLDATA vs. Revv 

While ALLDATA provides an ADAS Quick Reference Guide that shows users which ADAS systems are potentially on a vehicle, but not which require recalibration. In simple terms: They don’t provide specific calibration identification processes. This is a crucial gap in access to knowledge that shops need to resolve, which is where Revv comes in.

Revv is a specialized platform focused on identifying, documenting, and supporting proper ADAS calibrations in a collision repair or post-accident context. Revv helps shops monetize calibration work, ensure compliance, and support quality, whereas ALLDATA provides a broad service info library for fixing all vehicle systems. 

Revv also offers distinct advantages like automated reports for a vehicle’s VIN, fast identification of OEM ADAS calibration requirements, and calibration-specific invoicing. It can help your shop streamline workflows from quotes to invoicing throughout the entire repair and calibration process. 

Here’s a quick breakdown of key features of the two products: 

Feature ALLDATA Revv
Core Purpose OEM service info for diagnostics & mechanical repair Automates ADAS research & calibration identification
Primary User General repair techs, diagnosticians Collision shops, ADAS calibration centers, estimators, and compliance staff
ADAS Integration Limited (not calibration-focused) Purpose-built to identify OEM ADAS calibration requirements
Automation & Reports Manual lookup by VIN or system Automated reports via VIN and estimate integration
Invoicing & Documentation Not included Calibration-specific invoicing, documentation, and workflow tools
Data Source Direct OEM procedures OEM data + curated insights specific to calibrations & repair planning
Training & Consulting Self-guided OEM resources Optional consultative support, audits, training, and calibration vCFO
Integrations Some scan tool connectivity CCC, Mitchell, scan tools, invoice systems, and estimation software

Ultimately, you need both platforms for a successful repair in many cases, which is why we provide links in our reports that point to ALLDATA and specific calibration data that comes from the OEM. We’re also actively working on an integration with ALLDATA. 

The future of OEM repair information

As vehicles continue to evolve with more sophisticated driving and safety systems, access to accurate repair information will only become more critical. ALLDATA's commitment to providing unedited OEM data positions shops to meet these challenges while reducing liability and improving efficiency.

And when it comes to which tools you need, ALLDATA alone isn’t the answer. 

ALLDATA is a comprehensive repair manual platform for general diagnostics and mechanical/electrical work. You also need information about how to actually complete ADAS calibrations. You also need a platform that can help you quickly and accurately identify which calibrations need to happen and how to do so according to OEM instructions. The right suite of tools is essential, and ALLDATA and Revv are a powerful combination together.
