Diagnostic circuit for motor vehicle has bus system for controls with self monitoring function using non fluid memory for sensor data

摘要

The diagnostic circuit for a motor vehicle has controls (1) connected to a bus system(2) self-monitored by a non-fluid memory (4) for sensor data. The memory is connected to a dashboard-mounted display (3). The commencement of the diagnosis function occurs through the monitoring of an actuator (5), so that the memory stored data is automatically sent to the display via the bus system Claims include a method of vehicle operation diagnosis using the circuit.
