PROGRAM OR HIDE MODULES: The 5 ft. Ethernet to OBD cable gives you control over the modules available in your BMW. Modules are the separate computer programs that run various aspects of your vehicle, from the physical function to the accessories and tools of your vehicle. With this cable and a diagnostic tool, you can choose to program a single module or hide multiple modules. This all works through the ENET data line and the E-SYS ICOM coding. HIGH QUALITY CABLE FOR PROFESSIONAL USE: The CAT5e Ethernet Cable is durable and suitable for professional use. It is abrasion-resistant with gold plating and a grounded and shielded RJ45 connector. The 16-pin OBD connector is flexible so that shifting around with your computer wont damage the cars connector. Pure copper, metal film resistors, and lead-free solder all mean that this cable will work for years to come. Once you start tinkering with the modules on your car, youll be keeping it. COMPATIBLE CAR MODELS: This OBD Interface Cable is specifically for BMW vehicles. It works with many different BMW models. BMW owners purchase their vehicles because they want a top-of-the-line car that looks great, has plenty of power, and perhaps more than anything else is entirely under their control. By modifying various E-SYS modules, youll have more control than you can imagine. Supported BMW models include: BMW F-series, the new 1 Series, 3 Series, 5 Series, 7 Series, GT, X3 and the latest BMW G-Series.
