Main features

This tool will provide you with a wide range of features and capabilities, making it an ideal choice for professional mechanics and enthusiasts alike. Let’s take a look at the essential elements!

1. Read and clear code

Reads all the codes that are related to engine problems. It reads ABS brake diagnosis trouble codes of all modules.

It can’t read the airbag code or any module coupled to the body control system. Furthermore, it reads freeze frame data like engine speed, intake manifold pressure, fuel trim, injector pulse widths.

Read and clear code with data stream on all systems for heavy vehicles (gross weight under 26500 kg) like a truck, bus, and trailer. You can use this tool as an ordinary Automotive Code Reader and Data Stream Reader for heavy vehicles.

2. Live data

Can show the OBD2 diagnostic trouble code DTCs graphically, monitor status indicators, and check other vehicle control systems. It can import the service information from the internet automatically.

Customize your service specifications according to your applications. Once you are done with customizing, you can go for data printing and even share it. Live data is visible in text or graph mode. You can choose one of them according to your needs.

3. Compatibility

Let’s take a closer look! What a compatible device it is, right? This tool is compatible with all 1996 and amp; newer cars and amp; light trucks sold in the United States except hybrid or electric vehicles.

It supports all 10 test modes of the latest J1979 OBD II test specs, including reading Codes, Erase codes, Live Data, Freeze Frame, I/M Readiness, O2 Monitor Test, On-BoardMonitor Test, Component Test, and Vehicle Information.

4. ABS system

It includes an advanced ABS system, no doubt. As you may know, ABS is the primary reason why cars don’t go into lock-ups when braking.

When a car’s wheels aren’t rotating as fast as they need to be, the system pumps the brake fluid quickly, and it makes the wheels rotate so that at least one of them will have enough speed for turning. Simply put, ABS is an intelligent braking system that does not allow the wheels to lock up during braking.

5. SRS diagnostic trouble codes

You can retrieve diagnostic trouble codes through the Autel MaxiLink Scanner, a must-have for DIYers or professionals.

This scanner is designed to allow you to make certain engine diagnostic checks at home or on the road. It contains a huge database of the known sensors and system failures for easy reference.

6. Diagnose Transmission Problems

This Obdii scan tool aids in diagnosing transmits on problems within seconds. It can identify a faulty line pressure solenoid, an issue that frequently exists in cars with automatic transmissions.

The Autel MaxiLink Scanner serves as a diagnostic and repairs tool, making it one of the most popular tools for professional mechanics to use. It’s not only used to diagnose transmission problems but many other parts of your car or truck.

7. Checks The Engine

Autel MaxiLink is the best OBD2 scanner for reading and clearing check engine lights. There is an SD card slot in the scanner to read trouble codes from the vehicle computer. The trouble codes are visible on the Autel MaxiLink screen within seconds.

8. On-Board monitor test

The Autel MaxiLink is a new generation diagnostic device with an on-board monitor test function integrated. The primary function includes quick and easy diagnosis of the engine, transmission, airbag, ABS, etc., all in one tool kit.

Advanced features

Autel has patented all kinds of innovative technology and used top-grade materials when designing this product. Let’s discuss a few advanced features!

1. ECU

It includes a versatile electronic control unit for better functioning and efficiency. The 4.8-inch color touchscreen presents vehicle data for quick and easy readability.

Live Data Reads and displays ECU information from the vehicle’s on-board computer to monitor critical parameters, flag potential problems, help diagnose issues, reduce emissions and improve overall performance.

2. DPF

It features a diesel particulate filter monitor option: automatic transmission and an electronic brake system. Oil light, battery voltage monitor, engine coolant temperature, etc., are the advanced features this tool includes.

3. Built-in DTC lookup library

Autel MaxiLink ML629 provides you with the most comprehensive DTC database available. It can quickly locate and display up to 5 Vehicle DTCs, including both generic and manufacturer-specific

Diagnostic Trouble Codes (DTCs)  and their definition right on your OBD2 scanner’s screen.   With Autel Maxi Scanner, you will be able to immediately know how serious the problem is and what components need to be replaced – saving both time and money.

4. Software and updates will offer free software download services of SP18 and SP22; for these two scanners, use the trial version to view the vehicle information.

However, if you want to save data of multiple vehicles, it is better to buy a premium subscription that costs $19.99/month or $199/year;

It enables you to save all data and curves of vehicles and allows them to be viewed online. The free update service for the scanners comes with a PC Link and a USB cable which you can download or purchase separately.

Key differences between Autel ML629 and ML619

Autel has two scanners that look exactly the same but have differences. The ML619 and the ML629 are both OBDII vehicle diagnostic tools powered by Autel’s powerful MaxiScan platform, which means they have lots of functions, including real-time data graphing, live data reading, sensor monitoring, and ECU information.

They also both use the same update software – the MaxiLink PC update suite that allows you to check for updates and download new vehicle coverage files.

The ML629 features Bluetooth connectivity making it a wireless scanner, while the ML619 has no such feature and comes with a USB cable. Both scanners can be plugged into a PC and support Windows XP to Windows 7.

They are both pretty much the same except for the Bluetooth capabilities in the ML629. The ML619 is priced at $419.95, while the ML629 costs $529.95.
