Importance of having a diagnostic tool
Choosing the right diagnostic tool for your vehicle is like having a superpower. It helps you spot and fix problems quickly, saves you money, and keeps you safe on the road.
Plus, it gives you the chance to handle those minor issues that could cost you hundreds at the mechanic. Whether you’re a DIY enthusiast or a professional, it’s your secret key to the realm of vehicle maintenance.
1. Autel AL539
The Autel AL539 is a versatile and advanced automotive diagnostic tool.
Basic Features of Autel AL539
- Multifunctional Scanner: The AL539 can perform various diagnostic functions, including reading and clearing diagnostic trouble codes (DTCs), retrieving live sensor data, and conducting electrical circuit tests.
- User-Friendly Interface: The AL539 features a user-friendly interface with a color display and intuitive navigation. It provides clear and detailed diagnostic information, making it easy to interpret and analyze data.
- Wide Vehicle Coverage: This diagnostic tool is compatible with a wide range of vehicles, including cars, SUVs, and light trucks. It supports OBDII protocols and can work with vehicles manufactured from 1996 onwards.
Advanced features of Autel AL539
- Battery Testing: The AL539 is equipped with a battery test function that allows users to check the health and performance of the vehicle’s battery. It can provide accurate readings of voltage, starting power, and overall battery condition.
- Electrical Testing: With its built-in multimeter, the AL539 can measure voltage, current, and resistance in the vehicle’s electrical system. This feature is useful for identifying electrical issues and checking the integrity of circuits and components.
- Onboard Monitor Test: This diagnostic tool can perform an onboard monitor test to check the status and functionality of the vehicle’s emission control system. It can help identify any issues that may cause the vehicle to fail emission tests. (as required in some EU & U.S. states)
Limitation of Autel AL539
- No Battery and Oil light reset: Autel AL539 is not equipped with the feature to reset & clear the oil light when your car’s engine oil light is illuminated.
Notes: For context, an Oil light appears on your dashboard when drops to an unexpected level, or when your oil pump is malfunctioning. In either case, a DTC code will be generated in your car and most likely a ‘check-engine’ light will also lighten up along with it.

- Price: The AL539 is a professional-grade diagnostic tool, which may make it relatively more expensive compared to basic scanners. However, its advanced features and functionalities justify the investment for mechanics and automotive enthusiasts seeking comprehensive diagnostic capabilities.
- Missing feature – Oil & battery reset: As mentioned under the limitations sub-heading, the Autel AL539 does not include a basic feature of an OBD-2 scanner that is resetting the Oil & Battery light.
- Does not include advanced features like ABS bleeding and SAS calibration
Overall, The Autel AL539 is a reliable and powerful diagnostic tool that can assist in diagnosing and troubleshooting vehicle electrical systems. It is a valuable tool for mechanics and automotive enthusiasts who want to perform in-depth diagnostics and ensure optimal vehicle performance.
2. Autel AL539B
To be exact, it shares the same as the Autel AL539 as mentioned above, so rather than going all over again, I’ll proceed to describe the extra feature down below:
- Battery Testing: The AL539B is equipped with a battery test function that allows users to check the health and performance of the vehicle’s battery. It can provide accurate readings of voltage, starting power, and overall battery condition.
- Voltage Readings: The AL539B can provide accurate voltage readings of the battery. This is crucial information as it indicates the current charge level of the battery. Low voltage readings may suggest a weak or undercharged battery.
- Starting Power Assessment: Another valuable aspect of the battery test function is its ability to evaluate the starting power of the battery. It checks whether the battery can deliver the necessary electrical power to start the engine reliably. This assessment is particularly important, especially during cold weather or when dealing with older batteries.
- Overall Battery Condition: In addition to voltage and starting power, the Autel AL539B offers insights into the overall condition of the battery. It assesses factors like internal resistance and conductance, providing a comprehensive picture of the battery’s health.
