The automotive repair industry is constantly evolving, with vehicle technology becoming increasingly complex. Modern vehicles are equipped with advanced electronic safety systems that require careful attention during and after collision repairs. A critical process in ensuring vehicle safety and proper repair is performing pre- and post-repair system scans. The Equipment and Tool Institute (ETI), a respected voice in the automotive industry, strongly advocates for these scans. This article delves into why pre- and post-scans are essential, supported by ETI’s position on this vital procedure.
Understanding Pre- and Post-Repair System Scans
Pre-repair system scans, also known as pre-scans, are diagnostic procedures performed before any repair work begins on a vehicle. These scans utilize specialized tools to assess the vehicle’s electronic systems and identify any pre-existing issues or damage-related faults. The primary goal of a pre-scan is to create a comprehensive baseline of the vehicle’s condition before repairs commence.
Post-repair system scans, or post-scans, are conducted after the completion of collision repairs. These scans are crucial for verifying that all electronic systems are functioning correctly and that no new issues have arisen during the repair process. Post-scans ensure that safety systems, such as airbags, anti-lock braking systems (ABS), and Advanced Driver Assistance Systems (ADAS), are operating as intended.

Why are Pre- and Post-Scans Necessary?
The necessity of pre- and post-scans stems from the intricate electronic architecture of today’s vehicles. Modern cars rely heavily on a network of sensors, computers, and actuators to control various functions, especially safety-critical systems.
Pre-scans are vital for several reasons:
- Accurate Damage Assessment: Pre-scans help identify all damage, including hidden electronic faults that may not be visually apparent. This ensures a complete and accurate repair estimate, preventing supplemental claims and delays.
- Effective Repair Scoping: By identifying pre-existing conditions and collision-related faults upfront, repair technicians can properly scope the repair process. This includes determining necessary repairs, parts, and calibration procedures.
- Informed Repair Decisions: Pre-scan data provides valuable insights into the vehicle’s condition, allowing repair professionals to make informed decisions throughout the repair process, leading to safer and more effective repairs.
Post-scans are equally critical for:
- Verification of System Functionality: Post-scans confirm that all repaired and related systems are functioning correctly after the repair. This is paramount for safety systems to ensure they will perform as designed in a subsequent collision.
- Fault Code Clearing and System Reset: Repairs can sometimes trigger new fault codes. Post-scans allow technicians to clear these codes and reset systems, ensuring no lingering issues affect vehicle performance or safety.
- Ensuring Complete and Safe Repair: A post-scan serves as a final check to guarantee that the vehicle has been returned to its pre-accident safety standards regarding electronic systems. This protects both the vehicle owner and future occupants.
Challenges for Independent Repair Shops
While the importance of pre- and post-scans is clear, independent repair shops face unique challenges in implementing these procedures. Unlike OEM dealership facilities, independent shops service a wide range of vehicle makes and models.
- Cost of OEM Scan Tools: Acquiring OEM scan tools for every vehicle brand can be prohibitively expensive for independent shops. The investment in multiple OEM-specific tools may not be financially viable.
- Tool Accessibility and Affordability: Access to affordable and accurate scan tools capable of performing pre- and post-scans across various makes is crucial. The aftermarket tool industry plays a vital role in providing these solutions.
- Data Access and Timeliness: Aftermarket tool manufacturers rely on OEM data to develop effective scan tools. Timely and affordable access to this OEM data is essential for ensuring aftermarket tools can accurately emulate factory tool functions.
The Role of Aftermarket Scan Tools
Recognizing these challenges, the Equipment and Tool Institute (ETI) emphasizes the importance of accurate, timely, and affordable OEM scan tool data being accessible to the aftermarket. High-quality aftermarket scan tools offer a viable solution for independent repair shops.
- Capabilities of Aftermarket Tools: Many advanced aftermarket scan tools provide the necessary functions to perform pre- and post-scans effectively for a broad range of vehicles. These tools often offer comprehensive diagnostic capabilities comparable to OEM tools for common procedures.
- Data-Driven Development: Aftermarket tool manufacturers utilize OEM data, often provided through agreements, to develop tools that can accurately diagnose and manage vehicle systems. This data access is vital for the aftermarket to keep pace with vehicle technology advancements.
- ETI’s Support for OEM Tools When Necessary: ETI acknowledges that OEM tools may be necessary in certain situations, particularly for newer vehicles where aftermarket tool coverage may be still developing or for highly specific OEM procedures. Repairers should utilize OEM tools when required or when they offer the most appropriate solution.
ETI’s Position and Industry Impact
The Equipment and Tool Institute (ETI) unequivocally supports the use of pre- and post-repair system scans as a standard practice in collision repair. ETI’s position statement reinforces the growing industry consensus on the necessity of these scans for ensuring vehicle safety and proper repair quality.
ETI’s stance is significant because it represents a collective voice of automotive tool and equipment manufacturers and technical information providers. As an organization dedicated to advancing the vehicle service industry, ETI’s endorsement of pre- and post-scans highlights their critical role in modern automotive repair. Their advocacy helps to:
- Promote Industry Best Practices: ETI’s position encourages the widespread adoption of pre- and post-scans across the collision repair industry, establishing them as essential steps in the repair process.
- Support Repairer Education: By clearly stating their position, ETI contributes to educating repair professionals about the importance and benefits of system scanning.
- Advocate for Fair Data Access: ETI continues to advocate for fair and affordable access to OEM data for aftermarket tool manufacturers, ensuring independent shops have the tools they need to perform these vital scans.
Conclusion
Pre- and post-repair system scans are no longer optional procedures but essential requirements for ensuring the safe and complete repair of modern vehicles. As vehicle technology advances, these scans become increasingly critical for identifying damage, verifying system functionality, and upholding safety standards. The Equipment and Tool Institute’s strong endorsement of pre- and post-scans underscores their importance and reinforces the need for all repair facilities to incorporate these procedures into their standard workflow. By utilizing both advanced aftermarket tools and OEM tools when necessary, repair professionals can confidently navigate the complexities of modern vehicle electronics and deliver repairs that prioritize safety and quality.
