It supports a wide range of vehicle models and offers detailed step-by-step guidance, ensuring that technicians can perform ADAS sensor, camera, and radar calibrations in line with OEM specifications.

2. Ease of Use: 

Its intuitive interface simplifies the calibration process, reducing the learning curve and minimizing potential errors during calibration procedures.

3. Efficiency in Diagnostics and Calibration: 

By integrating both diagnostics and ADAS calibration into a single platform, the Autel Ultra streamlines workflow. Technicians can diagnose issues and then proceed directly to calibration without switching between multiple tools.

4. Accurate and Reliable:

Many users find that the Autel Ultra delivers precise calibration results, which is crucial for the proper functioning of ADAS features and overall vehicle safety.

5. Constant Updates and Support:

With ongoing software updates and technical support, the device remains current with new vehicle models and evolving ADAS technologies.

Given the above, the Autel Ultra stands out as a versatile tool that enhances both the accuracy and efficiency of ADAS calibration procedures.

The Autel MaxiSys Ultra is widely used for ADAS  calibration, covering multiple vehicle makes and models. Here are some examples of how it is applied in real-world scenarios:

1. Front Camera Calibration (Lane Departure Warning, Adaptive Cruise Control)

• Autel Ultra's Role: Guides the user through placing the ADAS calibration frame, aligning the target, and ensuring proper calibration using dynamic or static methods.
• Application: After windshield replacement on a Toyota Camry, the front camera needs recalibration.

2. Radar Sensor Calibration (Adaptive Cruise Control, Collision Avoidance)

• Autel Ultra's Role: Assists in positioning the radar reflector at a precise distance, ensuring alignment with OEM specifications for accurate cruise control and collision warning functions.
• Application: A Honda Accord with a replaced front radar sensor due to a minor accident.

3. 360-Degree Surround Camera Calibration

• Autel Ultra's Role: Aligns multiple cameras in vehicles equipped with a surround-view system, providing a seamless and accurate bird's-eye view for parking and maneuvering.
• Application: A BMW X5 with distorted 360-degree camera views after bumper repair.

4. Blind Spot Monitoring (BSM) Sensor Calibration

• Autel Ultra's Role: Calibrates side cameras and sensors that monitor blind spots, improving lane change assistance and overall side-view monitoring.
• Application: A Ford F-150 had its rear bumper replaced, affecting the BSM sensors.

5. Rear Camera Calibration (Reverse Camera, Parking Assist)

• Autel Ultra's Role: Guides the technician in setting up reference points for proper image alignment and trajectory correction.
• Application: A Mercedes-Benz E-Class with a replaced backup camera after an accident.

6. Lidar System Calibration (For Vehicles with Advanced Safety Features)

• Autel Ultra's Role: Provides step-by-step instructions for proper Lidar sensor alignment to ensure autopilot and emergency braking functions operate correctly.
• Application: A Tesla Model 3 requires recalibration after collision repair.

Why Autel Ultra for ADAS Calibration?

• Detailed Instructions: Clear, step-by-step procedures make calibration easy.
• Coverage: Supports a wide range of vehicle brands.
• Static & Dynamic Calibration: Offers both garage-based (static) and road-based (dynamic) calibration.
• Wireless VCMI Connection: Ensures smooth communication with the vehicle.

ADAS Using Experience 

De***te402 questioned on Reddit, 2 years ago: “ The question herein is that since every piece of service information out there states that the floor should be within 5mm tolerance when performing calibrations can mobile adas calibrations really be accurate?”

Below is the answer from de***rise:

I do mobile ADAS calibrations among other things and use a Autel MA600 stand. I’ve never had an issue as there are a lot of adjustments for this stand to get it level and square with the vehicle....Lighting has been more of an issue than the floor/ground for me. 

That is why I take the vehicle out and test drive it. Checking and testing the system that was calibrated. I’m not saying it can’t happen where it will pass and then throw a code later down the line but it has not happened to me personally.

I have heard of it happening to other techs but it’s usually because of a bent mounting bracket or the module was installed wrong or the tech did not fully tighten the module and it became lose. 

But usually if you follow manufactures instructions check tire pressures and follow weight distribution guidelines there is not an issue.

Also getting a four wheel alignment is very important and for whatever reason a lot of bodyshops want to skip this. 

A lot of shops will also R&I a bumper cover and not want to get it calibrated because they think it doesn’t need to be.

This will set off a DTC also. If there is a issue it is usually because of lazy techs not following the guidelines not how level the ground is. At least this has been my own personal experience.
