Not using OEM (Original Equipment Manufacturer) scanning tools for ADAS (Advanced Driver-Assistance Systems) work pose several dangers and risks, primarily due to the critical nature of these systems in ensuring vehicle safety. They are:

1. Inaccurate Calibration: ADAS systems rely on precise calibration to function correctly. Non-OEM tools may not have the same level of precision, leading to improper calibration. This can result in systems like lane-keeping assist, adaptive cruise control, or automatic emergency braking malfunctioning, potentially causing accidents.
2. Incomplete Diagnostics: Third-party tools might not have access to all manufacturer-specific codes or may not be able to diagnose all issues within the ADAS. This incomplete diagnosis could lead to unresolved faults that affect the vehicle’s safety.
3. Software Incompatibility: ADAS systems are often tightly integrated with a vehicle’s software. Non-OEM tools might not be fully compatible with the latest software updates or proprietary systems, leading to incorrect diagnoses or even causing malfunctions.
4. Voided Warranty: Using non-OEM tools for maintenance or repairs can void the manufacturer’s warranty. If a problem arises related to ADAS, it may not be covered if the manufacturer determines that non-OEM equipment was used.
5. Legal and Liability Issues: In the event of an accident linked to a malfunctioning ADAS, the use of non-OEM tools for diagnostics or calibration could lead to legal repercussions or liability issues, especially if it’s found that the equipment contributed to an improper repair or maintenance.
6. Safety Hazards: ADAS technologies are designed to enhance safety (like collision avoidance, pedestrian detection, etc.). Faulty operation due to incorrect tool usage can significantly compromise these safety features, increasing the risk of accidents.
7. Lack of Manufacturer Support: In case of complex issues, OEMs provide support and guidance for their tools, which might not be available for third-party tools. This lack of support can lead to challenges in resolving intricate ADAS-related issues.

Given the complexity and safety-critical nature of ADAS, the use of OEM scanning tools from our perspective is recommended to ensure the highest standards of safety, accuracy, and reliability. We don’t use third-party scan tools because the risks associated with their use in ADAS work can be significant, especially in a professional auto repair setting.
