OBD-II is the standard 16-pin diagnostic connector found in most vehicles. This adapter connects between your OBD-II port and your OBD-II communication device. It provides the correct CAN bus termination necessary for reliable data communication and can help resolve error messages such as \"no communication\" or the HP Tuners Detect Protocol Failed error.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWe manufacture this durable Nylon 12 housing using Selective Laser Sintering (SLS), a high-precision 3D printing technology that builds parts by fusing layers of the Nylon 12 powder with a laser. This additive manufacturing technique offers better material properties than more common hobbyist 3D printing, such as Fused Deposition Modeling (FDM), where objects are built by extruding melted plastic layer-by-layer.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003e\u003cspan data-preserver-spaces=\"true\"\u003eWhen would I use something like this?\u003c\/span\u003e\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eYou would use this device when \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003etrying to communicate\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e with an Engine Control Unit (ECU) that does not have internal CAN bus termination. A 120Ω terminating resistor must be on the network for CAN-based communication to work. For example, some General Motors Transmission Control Modules (TCMs) lack an internal 120Ω resistor, though the T42 and T43 models have one. Without the correct termination, you can't establish a connection. \u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003eNote that our\u003c\/span\u003e\u003cspan data-preserver-spaces=\"true\"\u003e current \u003c\/span\u003e\u003ca href=\"https:\/\/benchforce.com\/collections\/powerblocks\" class=\"editor-rtfLink\" target=\"_blank\"\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePowerBlock Switch Assemblies\u003c\/span\u003e\u003c\/a\u003e\u003cspan data-preserver-spaces=\"true\"\u003e include a 3-way ignition switch that enables 120Ω CAN termination when needed.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eHere's a more specific example.
