Task H-23 Diagnoses vehicle management systems
Task descriptor
Vehicle management systems use several ECUs to control the integration of many functions in the operation of the motorcycle such as fuel injection, ignition control, meter displays, anti-theft management, traction control and ABS. These ECUs communicate with each other through a Controller Area Network (CAN) bus system. Motorcycle technicians use special tools such as multimeters, diagnostic software and computers to diagnose and identify faults within the systems.
