If the terminating resistor (is shown with a dotted line in the diagram) is not installed on the vehicleside, it should be installed. Its presence can be checked with the help of a multimeter: it is necessary tomeasure the resistance between CAN_H and CAN_L when the vehicle electronics is off. If the resistance isabout 60 Ohm, there is no need for a terminating resistor. If the resistance is 120 Ohm, it is necessary toconnect a standard 120 Ohm resistor between the CAN_H and CAN_L wires.2. Connection with current-limiting resistorsTo plug the Terminal into the troubleshooting socket it is necessary to use the first connection variant.The second variant is recommended only for use to connect the Terminal directly to the vehicle’s CAN-bus.CAN_L CAN_HVehicleCANHCANLGNDcanGND1kOhm1kOhmCAN_L CAN_H GNDVehicleCANHCANLGNDcan1201kOhm
