Autel Autolink AL539B OBDII CAN Fault Code Reader And Electrical Battery Test Tool

Autel AutoLink AL539B OBDII/EOBD Scanner is an ultimate automotive analyzer that combines AVOmeter, Battery Test, and Code Reader specially designed to work with most 1996 and newer American, Asian and European OBDII/CAN compliant vehicles, which offers comprehensive vehicle analysis for rapid, accurate diagnosis and timely repair.

3-IN-1 Combo: OBD2 Scanner + Multimeter + Battery Tester

On a cold morning, you’re rushing to work, but the car cannot start?! A battery with no electrical charge is often the main cause of a non-start.

And when you customize the car (e.g. ECU coding, J2534 programming), if the electrical and battery system isn’t functioning properly, you are engaging in very risky behavior.

It is a good idea to get a battery test first.

Pick up this quality diagnostic scanner Autel AL539B combined with battery testing to handle the issue:

3-in-1 Combo: an OBDII scanner, a multimeter, and a battery tester (for battery health/starter/charging system).

Vehicle Coverage: most 1996 and newer OBDII & CAN vehicles across the globe.

Full OBD2 Modes Test: turn off the CEL; help pass the smog test; detect most emission-related car issues (graphic live stream, freeze frame data, o2 sensor test, etc.).

Patented One-click I/M Readiness: for fast and easy emission readiness check.

Multimeter (AVOmeter): diagnose the vehicle electrical system (DC or AC voltage, continuity, and current) to simplify the troubleshooting.

Battery Health Tester: load-free testing of most 12V batteries health status (Type: Regular, AGM, AGM/Spiral, Gel; Rating: CCA, CA, MCA, JIS, DIN, SAE, IEC, EN).

Starter Tester: help predict if the battery will fail to start a vehicle.

Charging System Tester: check if the output voltage and the charging current is normal.

More: data record and review; multilingual menu (EN, ES, FR …), DTC definition; internet updateable; data printable via PC.

>> Circuit Test (as a Multimeter / AVOmeter)

This is a simple to use and feature-packed diagnostic code reader. Contact the probes to a circuit, and you can use it as a multimeter / AVOmeter:

• Test the voltage in both AC or DC components (if > 30V, the scan tool may be damaged).
• Test the resistance between two circuit points (if > 50 ohms, it will display 0L).
• Measure the flow of current between 0A~20A (if >20A, the scan tool may be damaged).
• Can test the diodes (connect the probes to battery terminals correctly).

>> Battery Test (diagnose battery health, starter, and charging system status)

Connect this OBD2 scanner to your vechile via DLC port, or contact the probes to the battery’s terminals. You can also use it to test the battery health, starter, and charging system status.

Battery Health Test: show battery voltage, and the CCA value in seconds, with concise suggestion of “Good Battery, Charge Battery, and Bad Battery” for your reference.

Starter Status Test: show crank volt, volt percent, and the crank time, with recommendations of “Cranking Normal, Cranking Abnormal, Cranking Low, and Charge Battery” for you to make the proper decision

Charging System Test: help you find out if the output voltage of the generator, and the charging current is high or low, or if there is an excessive ripple.

All Modes OBDII Scanner

The full modes of OBDII diagnostics give you a window into what may be wrong when the check engine light comes on. So you can gain insight into engine health, and even make repairs yourself instead of paying a mechanic.

1. Read DTCs (Diagnostic Trouble Codes): to locate the trouble area associated with Check Engine Light.
2. Clear DTCs (Diagnostic Trouble Codes): to turn off Check Engine Light after servicing and repairing.
3. View dynamic Live Data: to know how the car is performing.
4. Display I/M Readiness Status: to know if the car is ready for the emissions test.
5. Show Freeze Frame Data: to see what happened when the fault code was set.
6. O2 Sensor Test: to check fuel efficiency and emission status.
7. EVAP Test: for fuel tank system (carbon canister test).
8. Access to on-Board Diagnostic Monitoring Test Results: to determine if some specific components or the monitors are normal.
9. Retrieve vehicle information (VIN, CID, and CVN): to track car details and historical records.
10. Read generic (P0, P2, P3, and U0) and manufacturer-specific (P1, P3, and U1) codes; show the DTCs definition directly, save the search online.
