#CMT# #/CMT# The method involves connecting loads (14) with a vehicle control device (12) by a power supply line (16) for the purpose of power supply and data exchange, where the loads transmit a status message (M) to the control device over the line in a preset sequence. Each of the loads is assigned to each different characteristic (26), where the control device transmits a status request (A) to the loads with low or high characteristics, in order to initiate a diagnostic method. #CMT#USE : #/CMT# Used for diagnosing the loads of a motor vehicle using a diagnostic device (claimed). #CMT#ADVANTAGE : #/CMT# The loads are connected with the vehicle control device by the power supply line for the purpose of the power supply and data exchange, thus eliminating the need for additional signal line or data line and hence facilitating retrofitting of a diagnostic device without large complexity and with small costs in any motor vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block representation of a diagnostic device. A : Status request M : Status message 12 : Vehicle control device 14 : Loads 16 : Power supply line 26 : Characteristic. |
