AD410Pro reads and clears engine codes while also testing your car's battery and alternator health. This dual functionality is especially useful since battery issues can sometimes trigger check engine lights or cause starting problems alongside diagnostic needs.

Test your battery before: Daily commutes | Road trips | After jump-starts | Long parking periods | When your battery keeps dying

Clear Results at a Glance: GOOD BATTERY / RECHARGE / REPLACE BATTERY / BAD CELL / CHARGE & RETEST

Hard Start? Slow Cranking? Find Out Early. A weak battery may still power lights, but fail during engine startup. AD410 PRO checks cranking voltage and cranking time to help identify weak batteries or starting system issues before they become a no-start problem.

Clear Starting Status: CRANKING NORMAL / LOW VOLTAGE / STARTING ISSUE

Battery Keeps Draining? Check the Charging System. A good battery can still lose power if the alternator is not charging properly. AD410 PRO checks unloaded voltage, loaded voltage, and ripple voltage to help identify charging system issues before they damage the battery or leave you with a no-start problem.

Clear Charging Status: CHARGING NORMAL / VOLTAGE LOW / RIPPLE HIGH / CHARGING ISSUE

Ready for a Smog Check? Know Before You Go. Check your vehicle’s I/M readiness status in one click before heading to the testing center. AD410 PRO shows whether your car is emission-test ready or not, helping you avoid failed inspections, extra trips, and unnecessary testing fees.

Ideal before annual inspections, smog checks, or after clearing trouble codes.

Code Pxxxx? Know What It Means Fast. AD410 PRO helps you look up fault code definitions and possible causes right on the device, so you don’t have to search online or guess what triggered the check engine light. Quickly understand engine, sensor, fuel, or emission-related issues and take the next step with more confidence.

Ideal for faster troubleshooting before repairs or mechanic visits.

What makes the AD410 Pro different from regular OBD2 scanners?

Upgraded from the popular AD310/AD410 OBD2 scanner, the AD410 Pro adds professional battery testing. Compared with two separate tools, its dual-system diagnosis delivers more accurate results, saving your cost, space and time.

Is the AD410 Pro compatible with my vehicle?

Yes! It works with OBD2-compliant cars, motorcycles, SUVs and light trucks. US models 1996+, European 2001+, Asian 2005+. Supports 12V batteries. Please confirm compatibility before purchase.

Does it require a separate app or subscription?

No app, no subscription, no internet connection and no installation required. It’s plug-and-play and ready to use even outdoors.

Can this device clear the check engine light after fixing the issue?

Absolutely. After you've repaired the issue, you can use it to clear the diagnostic trouble codes, which will turn off the check engine light. It also helps verify that the issue has been fully resolved before emissions testing or further driving.

What if the scanner doesn't work or gives an error?

First, ensure your vehicle's ignition is ON (engine doesn't need to be running). If issues persist:

1. Check and clean the OBD2 port

2. Restart the scanner

3. Update firmware (free download)

“Total lifesaver for my 2019 F-150! Last week check engine light popped on, truck hesitated starting pre-work. Grabbed this 2-in-1 tool—scanned code flagged evaporative leak (loose gas cap), battery test showed low charge not dead. Skipped $100 diagnostic + $200 battery replacement. Zero skills needed! Wish I’d bought it sooner!”

“We have 3 cars: Civic, Explorer, beat-up Jetta. The AD410 Pro works on all! Wife uses battery tester pre-trips, I use engine scanner for check engine lights. Fast, accurate—worth every penny for busy families!”
