Installation and maintenance of OBD2 16 pin to open end cable

The installation and daily maintenance of OBD2 16 pin to open end cables directly affect the effectiveness of diagnostic equipment and cable life. During operation, common risks such as wiring errors and insufficient protection should be avoided to ensure stable diagnostic work.

Two points should be noted during the installation process: first, the corresponding wiring of the pins. Before installation, it is necessary to refer to the OBD2 interface pin definition table of the vehicle and the wiring requirements of the diagnostic equipment, clarify the function of each wire core, use cold pressed terminals or welding methods to connect, and avoid wire core virtual connection or misconnection - if the power pin is confused with the signal pin, it may burn out the ECU or diagnostic equipment. The second is fixed interface protection. After the connection is completed, it is necessary to wrap the interface with insulating tape to prevent the wire core from being exposed and causing a short circuit; If used during vehicle operation (such as dynamic data monitoring), cable ties should be used to secure the cables to the body harness to avoid interface detachment or core wear caused by vibration.

There are three tasks that need to be done for daily maintenance: first, regularly inspect the appearance to see if there are cracks or aging on the outer layer of the cable, and if there is oxidation or rust at the interface. If any problems are found, replace them in a timely manner; Secondly, avoid excessive bending to prevent internal copper core breakage; The third is to control the storage environment. When idle, the cables should be stored in a dry, room temperature toolbox to avoid contact with oil stains and corrosive liquids. At the same time, they should be kept away from strong magnetic fields to prevent the performance of the shielding layer from deteriorating.
