Autel AutoLink AL519 OBD2 Scanner Handheld Diagnostic Tool — Universal 1996+ OBDII, Live Data & Readiness

The AL519 is an upgraded, budget-friendly scan tool from Autel that expands on basic code readers by offering all ten OBDII modes, quick DTC lookup, and simple live-data graphing. It's designed for DIYers and independent mechanics who need fast access to engine fault codes, I/M readiness, freeze-frame data and vehicle information without the complexity or price of professional shop tools. Note restrictions apply for certain FCA vehicles and Secure Gateway-equipped models.

What can the AL519 diagnose and reset?

The AL519 supports comprehensive OBDII functions used for engine and emissions troubleshooting. It reads generic and manufacturer codes, clears the Check Engine Light (CEL), shows live sensor data and retrieves freeze-frame snapshots to pinpoint conditions when a fault occurred.

• Read and erase stored, pending and freeze-frame DTCs (P0/P1/P2/P3, U0/U1)
• View live data in text and simple graph formats (RPM, fuel trim, coolant temp, etc.)
• Retrieve VIN, calibration IDs and CVNs for vehicle verification
• Evap test, O2 monitor test, on-board monitor status and module presence

How does it help with smog checks and readiness tests?

The AL519 displays I/M readiness status so you can confirm emissions monitors are reporting as "Ready" before taking a vehicle for inspection. That helps avoid wasting time and fees by identifying incomplete monitors or unresolved faults that would fail a smog test.

• Read I/M readiness monitors for misfire, fuel, catalyst, O2 sensors, EVAP and more
• Clear codes after repairs and re-check monitor status for readiness
• Freeze-frame data helps confirm conditions that triggered emissions faults
• Useful for pre-test checks on used cars and post-repair verification

Which cars and situations is the AL519 compatible with?

The scanner is compatible with most OBDII-compliant vehicles sold in the U.S. from 1996 onward. However, recent FCA (Chrysler/Dodge/Jeep) vehicles with Secure Gateway or AutoAuth protections and some vehicles with SGW modules are not accessible for module-level or code-clearing functions.

• Works with standard OBDII vehicles (1996+ in the US market)
• Not supported for FCA models using SGW/AutoAuth after 2017
• Does not perform full manufacturer-specific system diagnostics
• Contact seller with VIN to confirm compatibility before purchase

How do I update language or get support for the AL519?

Language updates are available via Autel's update files and the MaxiLinkII Windows utility; Mac is not supported. For manuals and additional support, use the product page documents, seller messaging or the provided contact email to request the PDF user guide.

• Download language files from Autel and use MaxiLinkII on a Windows PC
• Connect AL519 by USB, select update file in MaxiLinkII to change language
• Manuals available in the product guides section or by seller request
• Seller offers compatibility checks—message with vehicle VIN before ordering

Who this is for: The Autel AL519 is best for car owners, DIY enthusiasts and independent technicians who want a reliable, portable OBD2 tool for engine and emissions troubleshooting without the expense of dealer-level equipment. If you require manufacturer-specific system tests or advanced ECU coding, consider higher-end Autel models (e.g., MD906 Pro, MK808BT Pro). Before buying, verify your vehicle’s compatibility—especially if you own a recent FCA model or a car with a Secure Gateway.
