 When it comes to automotive diagnostic tools, the Autel MaxiCOM Ultra Lite and Launch X431 Pro TT Elite are two popular choices among professionals and enthusiasts. Both devices offer powerful features, but they cater to slightly different needs. Here’s a detailed comparison to help you decide which one suits you best.

• Price and Value

Autel Ultra Lite: Priced €2,559.

Launch X431 Pro TT: More affordable at €687, making it a budget-friendly alternative.

Verdict: If cost is a major factor, the Launch X431 Pro TT offers excellent value for money.

• Features and Performance

Both tools perform similarly in terms of diagnostics, coding, and programming.

Autel Ultra Lite:

2. Nearly identical functionality (38 hot functions vs. Autel’s 40).
3. Faster diagnostics on some vehicles (e.g., BMW).

Verdict: If you prioritize a bigger screen and advanced manufacturer features, Autel is better. For portability and affordability, Launch is the winner.

• Updates and Long-Term Costs

Both devices come with two years of free updates.

Autel Updates cost ~€699/year after the free period.

Launch Updates cost ~€321/year, making it more economical.

Verdict: Launch is cheaper to maintain long-term.

• Build Quality & Accessories

How to Repair OBDSTAR X300 Classic G3 Cannot Start Up?

 If the OBDSTAR X300 Classic G3 fails to start up normally, you can diagnose the issue by opening the device case and using a multimeter set to the ohms range. Measure the resistance across both ends of capacitor C75.

• If the reading is approximately 0Ω, it indicates a short circuit likely caused by damaged components U17 and L8.
• Replacing U17 and L8 should resolve the startup issue.

Check the detailed operation guide below.

Note: OBDSTAR X300 Classic G3 (yellow) = KeyMaster G3 (green)

Step 1: Remove Protective Case and Screws
Take off the rubber protective case. Then, use a screwdriver to loosen and remove the hex screws securing the X300 Classic G3 device housing.

Step 2: Disconnect the Battery
Open the back cover. Press down on the battery connector clip and gently pull out the battery connector to safely disconnect power.

Step 3: Test Capacitor C75
Set a multimeter to the ohms (Ω) range and measure the resistance across both ends of capacitor C75.

• If the resistance is close to 0Ω, this indicates a short circuit caused by damaged components U17 and L8.
• Proceed with replacement of U17 and L8.

Step 4: Desolder and Replace U17 and L8
Use a soldering iron or hot air gun set to 350 ± 10°C to remove the faulty components.

• Important: Replace L8 with a 1uH inductor.

Step 5: Verify the Repair
After replacing the components, measure the resistance across C75 again.

• A reading of approximately 36KΩ confirms that U17 and L8 have been successfully replaced and the short circuit is resolved.

Step 6: Reconnect and Test
Reconnect the battery connector. Reassemble the back cover and press the power button to start the device.

If the OBDSTAR G3 powers on normally, the repair was successful.

Step 7: Final Assembly
Secure the back cover with screws and reinstall the rubber protective case. The repair is complete.
