How to Use Advanced Anyscan A30M Workflows: CAN FD, FCA AutoAuth, Logging, and Reports

Introduction

Modern vehicles are rapidly adopting new communication protocols and security architectures that leave older scan tools behind. The XTOOL Anyscan A30M stays current with built-in CAN FD support for 2020+ General Motors vehicles, FCA AutoAuth integration for Stellantis security gateways, and professional data-logging and report-generation tools. This final guide in the A30M series covers the workflows that separate the A30M from entry-level readers and even many shop-grade tools.

What You Need

XTOOL Anyscan A30M with fully updated firmware and vehicle software
Anyscan app with internet access for FCA AutoAuth token retrieval
Vehicle that uses CAN FD (2020+ GM) or FCA/Stellantis security gateway (2018+)
Stable internet connection during the session

Understanding CAN FD and Why It Matters

CAN FD (Controller Area Network with Flexible Data-Rate) is the next-generation vehicle bus protocol that replaces classic CAN 2.0 on newer vehicles. Compared to traditional CAN:

Higher data rate: Up to 5 Mbps (vs. 1 Mbps for classic CAN)
Larger payload: Up to 64 bytes per frame (vs. 8 bytes)
Faster diagnostics: Full-system scans complete in seconds rather than minutes

Starting with the 2020 model year, General Motors (and increasingly other manufacturers) began deploying CAN FD on the primary diagnostic bus. Older scan tools that only speak classic CAN cannot communicate with these modules at all.

Step 1: Identifying a CAN FD Vehicle

Plug the A30M into the OBD2 port and open the Anyscan app.
During vehicle identification, the app will display the detected protocol in the connection status area.
If the vehicle uses CAN FD, the A30M will automatically negotiate the higher data rate. No adapter or configuration change is required.

Visual confirmation: On CAN FD vehicles, the Vehicle LED on the A30M will flash green at a noticeably faster rate during communication compared to classic CAN vehicles.

Step 2: Full-System Scanning on CAN FD

The scanning procedure is identical to older vehicles, but the results come faster:

Tap Diagnose, then Auto Diagnosis.
The A30M will sweep all modules in 10–20 seconds versus 1–2 minutes on classic CAN.
Live data streams at higher refresh rates, making graphing smoother and more responsive.

Note: On some 2023+ GM full-size trucks and SUVs, certain modules (like the digital cockpit display) may only respond to CAN FD. Classic CAN tools will show these modules as "No Communication" even though the vehicle runs perfectly.

Step 3: Data Logging on CAN FD Vehicles

Enter Live Data for any module.
Configure your 8-in-1 graph layout as described in the live-data guide.
Tap the record button before beginning your test drive or symptom reproduction.
Drive the vehicle or operate the system. The higher bandwidth of CAN FD means more data points per second and finer resolution in the recording.
Stop the recording and navigate to Reports to review or export.

Pro tip: Use the higher data rate to catch rapid transient events. On classic CAN, a 200-millisecond fuel-pressure dip might be invisible. On CAN FD, it shows clearly as a sharp spike on the graph.

Understanding FCA AutoAuth and Stellantis Gateways

Starting in 2018, Fiat-Chrysler (now Stellantis) began installing security gateway modules on Chrysler, Dodge, Jeep, Ram, Fiat, Maserati, Alfa Romeo, and Porsche vehicles. These gateways block unauthorized diagnostic access to prevent hacking and theft.

To scan or service these vehicles, the tool must authenticate through AutoAuth—a cloud-based token system that verifies the technician's identity and grants temporary access.

Step 4: Setting Up FCA AutoAuth

In the Anyscan app, navigate to Settings or FCA AutoAuth.
Create or log in to your AutoAuth account. This is a free service provided by Stellantis for independent repair shops and DIY technicians.
Link your account credentials to the Anyscan app. The app stores a persistent token so you only need to log in once per device.
Ensure your phone has an active internet connection. AutoAuth requires real-time token validation.

Account requirements: You will need a valid email address and may be asked to provide a shop name or technician ID. Individual DIY users can enter their personal information.

Step 5: Scanning a Stellantis Vehicle with AutoAuth

Plug the A30M into a 2018+ Stellantis vehicle.
Attempt to identify the vehicle or enter Diagnose.
The A30M detects the security gateway and requests an AutoAuth token.
The Anyscan app communicates with the AutoAuth cloud service and retrieves a time-limited access token.
Once authenticated, the gateway opens diagnostic access and the A30M functions normally—full DTC reading, live data, active tests, and special functions.

Token behavior: Tokens are typically valid for the duration of your session. If you disconnect and reconnect hours later, the app will request a new token automatically.

Step 6: What You Can Do After AutoAuth

Once authenticated, the A30M has the same access as dealership tools on Stellantis vehicles:

Full DTC reading and clearing across all modules
Live data streaming from ECM, TCM, ABS, SRS, and body modules
Bi-directional active tests including EVAP, fuel pump, cooling fan, and window actuators
All special functions including oil reset, EPB, SAS calibration, and BMS registration
Module programming (on supported models and where calibration files are available)

Step 7: Recording and Managing Data Logs

The A30M's data-logging capability turns it into a flight recorder for your vehicle:

From any Live Data screen, tap the red record button to start capturing.
The log captures every selected PID at the maximum refresh rate the protocol allows.
Stop the recording with the stop button.
Navigate to Reports from the main menu.

In the Reports section you can:

Playback the log with synchronized graph scrubbing
Compare two recordings side by side (useful before/after repair verification)
Export as a CSV file for spreadsheet analysis
Share via email, messaging apps, or cloud storage

Step 8: Generating PDF Diagnostic Reports

After completing any diagnostic session, navigate back to the main menu step by step.
The Anyscan app will automatically prompt you to generate a report.
Select PDF Report from the Reports menu.
Choose what to include:

Vehicle information (VIN, make, model, year, mileage)
Scanned modules and their status
Trouble codes with definitions
Freeze-frame data
Screenshots of live data graphs
Active test results
Special functions performed

Tap Generate. The PDF is created locally on your phone.
Use the share button to send the PDF via email, upload to Google Drive, or print directly.

Business use: Mobile mechanics and small shops can attach these reports directly to customer invoices, providing professional documentation that builds trust and justifies repair recommendations.

Step 9: Managing Software Updates

Tap Updates from the main menu.
The app checks both the A30M firmware and the vehicle-brand diagnostic databases.
Tap Update All or select individual brands.

Update strategy:

Immediate: Update as soon as you see new CAN FD or FCA AutoAuth patches—these expand vehicle coverage.
Before a big job: If you are servicing an unfamiliar vehicle, update first to ensure you have the latest special functions.
Monthly maintenance: Check for updates monthly even if you are not scanning. XTOOL's free lifetime updates add value continuously.

Step 10: Using the Voltage Display for Preventive Diagnostics

The A30M's 1-inch LCD voltage readout is not just a convenience feature—it is a diagnostic tool:

12.6+ V — Healthy battery, fully charged
12.4–12.5 V — Acceptable, but verify before long coding sessions
12.0–12.3 V — Low charge; charge before deep diagnostics
Below 12.0 V — Discharged or failing battery; replace before scanning to avoid module corruption

Use the voltage display to catch weak batteries before they cause communication errors, phantom codes, or failed module programming. A $100 battery replacement prevents a $1,000 control-module headache.

Tips for Advanced Workflow Success

Always update before touching a 2020+ GM or 2018+ Stellantis vehicle. Protocol support changes rapidly, and an outdated app will fail silently on CAN FD or AutoAuth.
Keep your phone charged. CAN FD high-speed streaming and AutoAuth cloud communication drain battery faster than classic diagnostic sessions.
Log everything before clearing. A recorded log is evidence. A cleared code with no record is just a story.
Use the PDF report as a service selling tool. Show customers before-and-after reports with graphs. Visual proof converts skeptical customers faster than verbal explanations.
Back up your logs. Export CSV and PDF files to cloud storage immediately after recording. Phone storage fills up, and diagnostic data is not replaceable.
FCA AutoAuth requires internet every session. If you work in a dead-zone garage, set up a mobile hotspot or verify token access before starting the job.
