General Motors Position Statement: Pre- and Post-Repair System Scanning

As the industry continues to ask, are pre- and post-repair scans necessary, General Motors provides their answer.

Per the General Motors Pre- and Post-Scan of Collision Vehicles position statement: "General Motors takes the position that all vehicles being assessed for collision damage repairs must be tested for Diagnostic Trouble Codes (DTCs) during the repair estimation in order to identify the required repairs. Additionally, the vehicle must be retested after all repairs are complete in order to verify that the faults have been repaired and new faults have not been introduced during the course of repairs."

The GM position statement also identifies "Many safety and security-related components, sensors and Electronic Control Units (ECUs) require calibration and/or learns when replaced. These systems must be repaired according to the corresponding GM repair procedures in Service Information (GMSi)."
