AUTOOL was officially founded in March 2014 in Shenzhen, with an initial focus on automotive diagnostics and maintenance equipment.[1]

A significant early milestone occurred in June 2016 when AUTOOL introduced its first independently developed product, the CT150 fuel injector cleaner and tester. Fuel-injector cleaning and testing subsequently became one of the most recognizable areas of the brand’s product portfolio.[1]

The company’s international expansion accelerated in September 2019 when AUTOOL signed its first overseas distributor, leading to further growth in its global distribution network.[1]

AUTOOL reported that its global user base exceeded 2 million in July 2022. In October 2023, the company stated it was recognized as a National High-Tech Enterprise and received recognition associated with China’s “Specialized, Refined, and Innovative” enterprises.[1]

In March 2025, AUTOOL announced the relocation of its global headquarters to Xuehua Innovation Park in Shenzhen, describing the move as part of its long-term development plans.[1]

According to the company’s latest historical information, AUTOOL’s global user base exceeded 5 million in May 2026, while its production center expanded to 32,000 m² and its R&D center to 4,000 m². These figures are company-reported rather than independently audited.[1]

AUTOOL’s product range extends considerably beyond conventional OBD scanners. Its official catalog includes categories such as:[1][3]

• Automotive diagnostic equipment
• Fuel injector cleaners and testers
• Smoke leak detectors
• Automotive circuit testers
• Diagnostic multimeters
• Battery testers
• Engine pressure testers
• Spark-plug testers
• Oil and fluid analyzers
• Cooling-system testers and fillers
• Transmission-fluid exchangers
• Brake-fluid bleeders
• A/C system testing and servicing equipment
• Carbon-cleaning machines
• Dry-ice blasting machines
• Inspection cameras and borescopes
• Used-car inspection equipment
• ECU programming/inverter power supplies
• EV charging equipment
• EV battery testing equipment
• Wheel and tire equipment
• Vehicle lifting equipment
• Workshop storage and equipment

This breadth makes AUTOOL more accurately described as an automotive service-equipment brand rather than solely a car diagnostic scanner manufacturer.

Vehicle inspection and diagnostics constitute one of AUTOOL’s primary areas of operation. The portfolio includes diagnostic equipment, automotive circuit testers, diagnostic multimeters, battery testers, and OBD-related testing equipment designed to help technicians investigate electrical, electronic, and mechanical vehicle problems.[1]

For example, AUTOOL produces OBD protocol testing equipment designed to examine a vehicle’s OBD-II communication, power, and grounding circuits. Documentation for this equipment notes that it is intended primarily for automotive professionals, as improper connection to vehicle communication systems can potentially damage vehicle electronics.[2]

This highlights a key characteristic of the AUTOOL lineup: many products are designed as workshop diagnostic instruments rather than consumer gadgets.

Fuel-injector equipment holds a particularly important place in AUTOOL’s history. The CT150, launched in 2016, was the company’s first independently developed fuel-injector cleaner and tester.[1]

Subsequent equipment combines functions such as:

• Ultrasonic injector cleaning
• Injection-volume testing
• Injector uniformity testing
• Spray-pattern and atomization observation
• Leakage and sealing tests
• Electronic pressure control
• Testing under different simulated operating conditions

Documentation for the CT500 model, for instance, describes an electromechanical system combining ultrasonic cleaning technology with computerized oil-pressure control and injector testing.[1] This category has helped establish AUTOOL as a supplier of larger professional workshop machines in addition to handheld tools.

Automotive smoke-leak detection is another recognizable AUTOOL product category. Technicians use smoke machines to locate leaks in applicable vehicle systems, including intake, vacuum, and other piping systems. Documentation for the SDT203 describes the equipment as a diagnostic leak detector for vehicle pipe systems, listing applications across cars, motorcycles, snowmobiles, ATVs, light trucks, and boats.[1]

This product line reflects AUTOOL’s general philosophy of addressing physical testing and troubleshooting rather than relying exclusively on computerized fault codes.

AUTOOL has progressively expanded beyond diagnostic instruments into equipment used throughout an automotive workshop. The current catalog includes products for engine and fuel-system service, fluid exchange, cooling-system maintenance, brake servicing, air-conditioning servicing, carbon removal, oil extraction, tire servicing, vehicle lifting, and workshop organization.

The official store describes the brand as providing equipment for tire shops, auto centers, garages, and service-equipment distributors, covering applications including wheel alignment, A/C service, carbon cleaning, lifts, and workshop storage.[3] This expansion has positioned AUTOOL closer to a full-line automotive workshop-equipment supplier than a specialist diagnostic-tool manufacturer.

AUTOOL has also entered the electric-vehicle market. Its official product portfolio includes an EV charging series and equipment related to EV battery-pack air-tightness testing.[1]

The company’s broader strategy reflects the automotive industry’s transition toward electrification, with public promotion of products and technologies for battery testing, smart charging, and EV-related maintenance.[1] Consequently, the brand’s portfolio now spans both traditional internal-combustion-engine service and selected electric-vehicle workshop applications.

AUTOOL presents itself as a manufacturer with independent product-development capabilities rather than merely a reseller. The company states that its product design and development are driven by user requirements, emphasizing continuous improvement and innovation. It also provides OEM and ODM services, indicating that its manufacturing capabilities extend to customized or partner-developed products.[1]

AUTOOL reports holding ISO quality-management certification, design patents, utility-model patents, and software copyrights. These claims are presented by the company on its official corporate site.[1]

AUTOOL’s international strategy is central to its identity. The company states its products are available in more than 160 countries and regions through a combination of online and offline distribution channels.[1]

Regional operations and distribution arrangements have been established to support overseas customers. For example, AUTOOL USA was created to provide localized support and distribution for the U.S. market.[4]

The company participates in international automotive trade events, highlighting appearances at Automechanika Frankfurt, AAPEX, and various Asian automotive exhibitions.[1]

AUTOOL has specifically promoted its presence in the Philippines, including participation in the 2025 Manila Auto Parts & Vehicles Expo.[1]

AUTOOL’s products serve several distinct customer groups:

• Professional automotive technicians
• Independent repair shops
• Automotive dealerships and service centers
• Specialized workshops
• Fleet-maintenance operations
• Automotive parts and service businesses
• Automotive educators and training institutions
• DIY vehicle owners

Sophisticated equipment such as injector test benches, A/C machines, wheel equipment, and workshop machines is primarily oriented toward professional environments, while smaller diagnostic and testing tools may also be used by experienced DIY users.[4]

AUTOOL’s stated philosophy is “Mutual support, mutual success.” Its values center on responsibility toward products, users, and partners, with a stated vision to become a trusted company in the global automotive industry.[1]

The brand identifies itself visually through a yellow-and-black color scheme, which has become an integral part of its product and marketing identity.[5]

AUTOOL emphasizes product durability, quality control, and after-sales support. The official corporate website states that AUTOOL provides a 3-year warranty and lifetime service support, alongside technical-support, warranty, and product-documentation resources for customers.[1]

Exact warranty conditions can vary by product, market, and accessory; customers should consult the warranty documentation applicable to a particular model rather than assuming identical coverage across all components.

AUTOOL occupies a position between several traditional categories in the automotive tool market. It is not simply an OBD scanner company, as its portfolio includes physical testing and maintenance machinery alongside scanners and diagnostic equipment. Nor is it exclusively a workshop-equipment manufacturer, given its production of portable diagnostic and electrical instruments. Furthermore, it is not limited to internal-combustion vehicles, as its portfolio increasingly includes EV charging and battery-related equipment.

The resulting product strategy encompasses diagnosis, testing, cleaning, maintenance, repair, workshop equipment, and EV service. This breadth is one of AUTOOL’s defining characteristics.
