If a customer has a failed VIR check report, what should the technician recommend?

When a customer presents a failed Vehicle Inspection Report (VIR), it is crucial for the technician to first conduct a diagnosis to identify the specific issues contributing to the failure. This step is essential as it provides a clear understanding of the problems that need to be addressed, enabling the technician to recommend the most effective repairs. By identifying the root cause of the failure, the technician can focus on the specific components or systems that require attention, which is more efficient and effective than guessing what repairs might be needed.

Performing a retest without diagnosing issues may lead to repeated failures and customer frustration, while skipping the diagnosis and proceeding directly to repairs could result in unnecessary costs and work. Therefore, a thorough diagnosis is the best approach to resolving the problems indicated by a failed VIR effectively, ensuring the vehicle can meet emissions standards and the customer can pass subsequent inspections.
