    • A testing apparatus for an IPDM(Intelligent Power Distribution Module) is provided to facilitate a testing process of the IPDM by testing various relays and circuits in the IPDM, while the IPDM is mounted on an engine room. A testing apparatus for an IPDM(Intelligent Power Distribution Module) includes a cable connection terminal(102), plural contact terminals(110) and a CAN communication setting unit. The cable connection terminal is connected to the IPDM using a cable. The contact terminals receive result signals on relay states from the IPDM according to a test request signal from a vehicle. The connection terminals transmit the result signals to the cables, and the CAN(Controller Area Network) communication setting unit sets a communication scheme between the testing apparatus and the IPDM.
