METHOD FOR TESTING ELECTRONIC CONTROL DEVICES

The method for testing an electronic control device containing a microcomputer and a volatile memory for programs processed in the microcomputer includes transferring a program module for testing to the microcomputer (14) via a serial interface (SSO) prior to the testing, the program module including commands for executing individual data reading and writing operations in the control device (12) in response to respective test commands; writing the program module into the volatile memory (Code RAM) in the control device (12) prior to the testing; receiving test instructions including several test commands in the microcomputer (14) from an external test device (10) via the serial interface (SSO); processing the program module by the microcomputer (14) to test the control device (12); triggering a number of the individual data reading and writing operations in the control device (12) via the several test commands received in the control device (12); transferring data generated in the control device (12) during the processing of the program module and the triggering to the external test device and evaluating and/or displaying the data received in the external test device with the external test device.
