AL539B, a multifunctional diagnostic tool, is specially designed for advanced diagnosis. Besides full OBD2 functions, it features the capability of battery test, you can have circuit test, starting and charging systems tests, battery test with probes.
Special Battery Test of OBD2 Scanner
Compared with Autel AL539, AL539B is especially equipped with the capability of battery test which provides quick and accurate load-free testing of most type of 12V batteries, including AGM, standard and maintenance-free batteries. Make sure that the red cable is connected to positive (+) terminal, and black to negative (-) terminal, rock each clamp back and forth to make a good connection. It’s easy to operate with the instructions displayed on LCD screen, it doesn’t matter if you’re unfamiliar with the tool; clearly-ranked operating steps are your best assistance.
Battery test, in some respects, is an additional function to OBD2 scanner aiming at providing better services to customers.
Professional Electric Testing Functions
This car code reader is equipped with easy-to-read AVOmeter for circuit test, so you have the access to voltage, continuity and current testing near at hand. You can choose AUTO/DC Voltage/AC voltage mode to test different voltages for your convenience. In the continuity mode, if the resistance of circuit is less than 50 ohm, the scan tool would display actual value and alarm a beep, very safe and convenient. In current mode, you have choices of 20A and 200A for different current range; testing results of current between 2 probes are concisely displayed on the screen. However, Circuit test only available when the tool is powered by built-in 3.7V lithium battery solely. Otherwise, it will cause incorrect results and damage the tool.
Practical OBD2 Functions
Besides, this OBD2 code reader also supports practical OBD2 functions in order to offer you maximum pragmatism:
Live PCM data stream are vividly displayed on its crisp screen, so you can discover the abnormal parameters intuitively and figure out which part is wrong quickly.
Freeze frame data is accurately captured and stored by this code reader; hence you can diagnose your vehicle more efficiently based on the recorded information.
Emission test is also provided, including: I/M readiness status test, O2 sensor test and On-board monitor test. These comprehensive tests are bound to protect you from being fined.
Turning off Engine Light
The stored fault codes which indicate the fault have reoccurred for more than a special amount of key-cycle will cause the check Engine light on. However, you can turn it off by clearing the fault codes. This code reader is able to detect the cause of check engine light (MIL) easily and turn off the light on dashboard effectively. Much money-saving than going to an auto service center.
O2 Sensor Test
The automotive scan tool can test on the O2 sensor to identify problems related to fuel efficiency and vehicle emissions and make sure it performs well. Otherwise, the sensor on your vehicle may fall to get best fuel economy, lowest emissions and good power. By automatically detecting on the oxygen content in the exhaust you can easily figure out the vehicle health status.
