Autel AutoLink AL539B Fault Code Reader/Multimeter
The Autel AutoLink AL539B is a versatile 3-in-1 diagnostic tool that reads OBD2 error codes, tests electrical systems, and analyzes batteries. The device supports vehicles with OBD2 and CAN protocols from model year 1996. With its clear 2.8 inch TFT color display and intuitive operation, the AL539B is suitable for both DIY enthusiasts and professional mechanics.
In addition to standard OBD2 functions, the AL539B offers a built-in multimeter (AVOmeter) for measuring voltage, current, and resistance, as well as a battery test function for assessing the health of 12V batteries, starting and charging systems. The patented One-Click I/M Readiness button makes it easy to check the vehicle's emission status.
Diagnostic functions:
-
Reading Error Codes: Reads generic (P0, P2, P3, U0) and manufacturer-specific (P1, P3, U1) error codes, including pending codes.
-
Clear error codes: Removes error codes and turns off the malfunction indicator lamp (MIL).
-
Live Data: Displays real-time data from the engine management system in text and graph form.
-
Freeze Frame: Displays frozen data at the moment an error code was stored.
-
I/M Readiness: Checks the status of emission-related monitors for MOT inspections.
-
O2 sensor test: Analyzes the operation of lambda sensors.
-
On-board monitoring: Displays test results of emission-related components.
-
Component Test: Tests specific parts of the emission system.
-
Vehicle information: Retrieves vehicle data such as VIN, CIN, and CVN numbers.
Special functions:
-
Multimeter (AVOmeter): Measures AC/DC voltage, current (0–20A, 0–200mA), resistance, and diode function.
-
Battery Test: Performs load-free tests on 12V batteries (standard, AGM, gel) and assesses battery health.
-
Start/Charging System Test: Analyzes the performance of the vehicle's starting and charging system.
-
One-Click I/M Readiness: Quick check of emission components with the push of a button.
-
Data storage and printing: Saves diagnostic data and enables printing via PC.
-
Lifetime free updates: Free software updates via USB keep the scanner up to date.
