VOLVO Bus & Coach Fault Codes List

Service technicians have no problem recognising breakdowns and carrying out machine diagnostics, VOLVO Bus & Coach Fault Codes List, plus they are familiar with equipment from a variety of manufacturers.

Volvo Buses (Volvo Bus Corporation / formal name: Volvo Bussar AB) (stylized as VOLVO) is a subsidiary and a business area of the Swedish vehicle maker Volvo, which became an independent division in 1968. It is based in Gothenburg. It is one of the world’s largest bus manufacturers, with a complete range of heavy buses for passenger transportation. The product range includes complete buses and coaches as well as chassis combined with a comprehensive range of services. The bus operation has a global presence, with production in Europe, North and South America, Asia and Australia. In India it set up its production facility in Bangalore. A former production facility was located in Irvine, Scotland (closed in 2000).
