Abstract
In a method for the testing of an electronic device, particularly for automotive vehicles, having a microcomputer (2), an interface as well as device inputs and outputs (connector 6), the following separate test steps are provided: In one test step at least one predetermined combination of input signals is fed into the device inputs (connector 6), and the test output signals which occur in this connection at the inputs of hardware units (4, 8, 9) of the device (1) are picked up via the interface and compared externally with the combination of the input signals. In further test steps, test control signals are fed into a single hardware unit, and the test output signals produced thereby at the output of said hardware unit are picked up via the interface for an external normal/actual comparison. In a further test step, output test control signals are fed into at least one hardware unit (2, 3) which is connected with the device outputs and the output signals produced thereby at the device outputs (connector 6) are fed to an external normal/actual comparison.
