摘要：<p>The method involves providing test voltage to a device contact (102), and detecting evaluation voltage at an evaluation contact (122) that is connected with the device contact by a resistor (124) and with another device contact (104) by another resistor (126). Operating voltage is activated, and another evaluation voltage at the evaluation contact after the operating voltage is activated. The operating voltage is deactivated, and third evaluation voltage at the evaluation contact after the voltage is deactivated. Connection configuration is determined based on the three evaluation voltages. An independent claim is also included for a device for recognizing connection configuration of device attached to voltage terminals of a vehicle.</p>
