Method of checking vehicle mounted electronic units |
摘要 |
An electronic unit (1) mounted in a vehicle comprises a controller unit (2). The electronic unit (1) is tested by a test device (3) using periodic communications cycled therebetween. A frame of order signal is formulated by loading data designating several ports or the like and transmitted from the test device (3) to the controller unit (2). The latter processes the order signal (11, 12, 13) and returns the processed results to the test device (3). At least part of the above data are shortened from 8 bits to 4 bits, and several ports and the like are tested in one cycle of the periodic communications. The test time is thus reduced for this electronic unit. <IMAGE> |
