According to the company, GM’s goal is to ensure that all necessary repairs are diagnosed during the estimate process, and that vehicles are returned to customers in pre-crash condition. Testing is especially critical when safety systems are impacted.
“Even minor body damage or glass replacement may result in damage to one or more safety-related systems on the vehicle,” said John Eck, collision manager, GM Customer Care and Aftersales. “Any action that results in loss of battery-supplied voltage and disconnection of electrical circuits requires that the vehicle be tested post-repair to ensure proper electrical function.”
Many safety and security-related components, sensors and Electronic Control Units (ECUs) require calibration and/or “learns” when replaced, Eck stresses. These systems must be repaired according to the corresponding GM repair procedures.
"Technicians who follow proper pre- and post-repair scanning procedures have an edge when it comes to customer satisfaction because dashboard lights can’t tell you everything that’s going on with a vehicle’s electronics,” Eck said. “With pre- and post-scans, techs will start with the right diagnosis and right parts out of the gate; they’ll reduce repair cycle times and they should see fewer follow-up visits. More importantly, the scans will help ensure that the vehicle and its safety systems are returned to their pre-crash conditions.”
