In general, the operation of the body ECU is not sufficient conditions caused by the failure, and under normal circumstances, this harness has no measurement points outside, he is from the fuselage ECU fuse box through the internal plug-in connection, so this fault is too special Shu Re-repair the harness after troubleshooting.

Previously used in the production of automotive wiring harness in the form of manual management, is not conducive to the effective convergence of the various production processes, but also not conducive to the restructuring of enterprises according to the actual situation.

Fault code retrieval fault code, the meaning of the radiator fan relay control circuit failure. With TECH2 control radiator fan, the left and right side of the electronic fan operating at low speed, high-speed electronic fan does not turn left. Check the electronic fan fuse and found that the high-speed electronic fan fuse (15 A) is damaged, indicating a short circuit in the line or excessive load on the electronic fan.

Automotive wiring harness has a lot of wires, in order to facilitate identification and maintenance, the wires are used in different colors. In order to annotate the circuit diagram, the wire harness cross-sectional area of the car wiring is also marked in front of the color code.
