The proper torque of the connector for the chassis harness and the platform harness will increase the circuit continuity by preventing rust and corrosion of the pins and sockets. Use the correct tool and tighten the connector screw to 6.90 ± 0.35 N·m (61 ± 3.10 lb in). The connector may not be properly tightened on some machines and the circuit continuity may be lost. If any system malfunction occurs on the machine, check the connector and tighten the screw to the specified torque. The effectivity and the adaptability of the machines with the connector screw properly tightened are listed in Table 1.
