A vehicle diagnostic test can help ensure that the right repairs are made, and can save money by avoiding unnecessary repairs. A full diagnostic test can also provide information about when the vehicle needs its next tune-up, and the history of engine services and repairs. The process varies depending on the drivers reported concern and vehicle. The diagnosis process will involve the following steps, but is not limited to the below:

• Consultation with the driver regarding the symptoms of the complaint.
• Test driving the vehicle to confirm concern or carry out specific checks on isolated components.
• Connecting the diagnostic scan tool, which provides access to real-time data from the vehicle's systems and sensors.
• This data is then used to help identify the location of the problem.
• A series of tests and visual inspection can then be carried out to identify the root cause of the problem.
• A quotation and report will be provided to the customer with all relevant information regarding the next steps for repair.
