KD-3058 Auto EECS and ECU Examine-Analyzing



KD-3058, diagnostic tool of testing analyzing equipment of automobiles EECS and ECU, is specially designed for engineers who repair automobiles EECS and ECU. It is a handset and also can be used at worktable. It includes electric-control analyzing equipment and signal generator. According to the common characteristic if automobiles EECS,
the equipment can simulate 8 kinds of signals to meet the demands of diagnosing work. Moreover the equipment can simulate 3 kinds of independent, changeable signal combination at the same time
The equipment is designed on the basis of electric-control principle and repairing regularity, so it can also be a useful teaching tool to grasp Automobile-Electric technique in automobile repairing skill training.
