How to avoid J1939 to OBD2 cable damage?

To avoid damage to the J1939 to OBD2 cable, corresponding measures can be taken during use, storage, and maintenance, as follows:

Correctly plug and unplug。

When connecting and disconnecting cables, make sure to operate gently and accurately. Align the plug with the interface first to avoid skewed insertion and prevent bent or broken pins. When unplugging, hold the plug body instead of pulling the cable to avoid loosening or damaging the connection between the plug and cable.

Do not plug or unplug cables while the vehicle is running or the equipment is powered on. First, turn off the relevant power supply and wait for a moment before proceeding to prevent the instantaneous current generated during plug and unplug from damaging the electronic components inside the cable.

Avoid excessive bending and stretching

When installing cables, sufficient length should be reserved to avoid excessive bending, twisting, or stretching of the cables. Try to keep the cable in a natural and stretched state, and do not forcefully fix it in a position that may cause deformation.

Avoid contact or friction between cables and sharp objects to prevent scratching of the cable sheath and damage to the internal wires. If it is necessary to fix the cable to the vehicle, soft fixing materials such as nylon ties or rubber pads should be used to reduce pressure on the cable.

Prevent electromagnetic interference

Do not place cables near strong electromagnetic sources, such as the ignition system of an engine, a generator, etc., to avoid electromagnetic interference, affecting signal transmission, and even potentially damaging electronic components inside the cables.

Try to avoid laying cables in parallel with other high current and high voltage lines. If unavoidable, use cables with shielding layers and ensure that the shielding layer is well grounded to enhance anti-interference capabilities.
