OBD or On Board Diagnostics, originally conceived as part of emissions control legislation, has expanded to cover nearly every electronic function of a modern bike. Today, an OBD scan tool is absolutely essential to read and erase error messages, check system parameters, reset service warning lights, adjust fuelling, perform active tests, work on ABS brakes, chassis control systems, immobilisers and much more. The justification to invest in this type of tool is direct and indirect profit generation as well as saving your workshop time.
Investing in an OBD diagnostic tool and software updates has a cost but it is the norm to charge your customers for use of these tools - printouts can be generated and given to your customers to demonstrate faults, justify corrective work and improvements. Struggling without this type of tool will cost you countless hours of wasted technician time and the loss of disaffected customers.
