Motor vehicle diagnosis in terms of technical facilities requirements

This paper presents the importance of motor vehicle diagnostics for proper and safe operation of motor vehicles safe to drivers, other road users and the natural environment. Other benefits of diagnostic testing, such as a reduction in the vehicle operation costs, a narrower scope of required technical service, a reduction in the purchase costs of spare parts or minimization of service labour intensity are also presented. The paper lists and describes the essential requirements to be met by those who carry out business activity involving diagnostic testing, i.e. the requirements regarding appropriate marking, types and sizes of control stands, adjustment of the equipment to the needs and scope of the offered services, documentation required to carry out technical inspections, qualifications of inspection station staff and training courses for inspection staff. The paper further presents the regulations regarding deadlines for diagnostic tests, the scope and the method for carrying out vehicle technical inspections, the measurement conditions, the course of testing, the evaluation of test results and, depending on the vehicle type, the required additional tests.
