Disclosed are a connection diagnosis system of a car electronic device and a method thereof, capable of simplifying diagnosis by diagnosing a connection state generated in the car electronic device. According to the present invention, in case a first diagnosis target comprising a plurality of first connectors, a second diagnosis target comprising a plurality of second connectors in correspondence to the first connector and a plurality of connection ports connected to each of the first connector and the second connector are included, the second diagnosis target transmits a diagnosis feedback signal to the first diagnosis target through a first connection port among the plurality of connection ports by using a diagnosis logic performing multiple connection diagnosis among the first connectors and the second connectors. Hereby, the present invention can reduce maintenance and repair costs (correction costs) by being able to reduce the number of prior diagnosis feedback signals and the number of wiring and connector pins by using one diagnosis feedback signal only. |
