Quality Inspection and Maintenance of J1939 Cable

Regular quality inspection and maintenance are crucial to ensure the reliable operation of J1939 cables. Quality inspection mainly includes appearance inspection, electrical performance testing, and communication function testing.

The appearance inspection mainly checks whether the outer skin of the cable is damaged, aged, etc., and whether the connector is loose, corroded, etc. Electrical performance testing includes measuring parameters such as insulation resistance and conductivity resistance of cables to ensure that their electrical performance meets standard requirements. Communication function testing is conducted through professional testing equipment to simulate actual communication scenarios and check whether the communication function of cables is normal.

In daily maintenance, it is necessary to regularly clean the dust and dirt on the surface of the cable to prevent dust and dirt from entering the interior of the connector and affecting communication quality. At the same time, mechanical damage to the cable, such as compression, pulling, etc., should be avoided. If a cable malfunction is found, it should be replaced in a timely manner to avoid the fault expanding and affecting the normal operation of the vehicle. In addition, a comprehensive cable maintenance file should be established to record the usage and maintenance history of cables, providing reference for subsequent maintenance and management.
