Install J1939 9-pin cable, these steps should be correct

Installing J1939 9-pin cable is not as complicated as expected, but the steps cannot be messy, otherwise it will affect the use of the equipment and even damage the components. Below are the key steps.

The first step is to prepare well. First, confirm the cable model and equipment matching, such as whether the temperature resistance and length of the cable meet the equipment requirements. Then prepare tools such as screwdrivers and insulation tape, and disconnect the power supply of the equipment to avoid electric shock.

The second step is' cleaning the interface is important '. The cable interface of the device may have dust and oil stains. Clean it with a dry cloth. If the interface is rusted, gently polish it with fine sandpaper to ensure good contact, otherwise it will affect signal transmission.

Step three, 'Insert and secure correctly'. Align the cable plug with the pin position of the device interface, gently insert it, and hear a "click" sound to indicate that it is firmly inserted. Then use screws to fix the plug to prevent the cable from falling off when the device vibrates. When fixing, the force should be moderate and the screws should not be loosened.

The fourth step is "inspection and testing". After installation, reconnect the device power, start the device, and observe whether the dashboard data is normal, such as engine speed, oil pressure, and other data can be accurately displayed. If the data is abnormal, check whether the cable installation is in place in a timely manner.
