This adapter is required for CFMOTO ATVs in order to communicate with the ABS and EPS systems, where installed. NOTE: the adapter has an OBD base. In order to connect with the vehicle, the 3151/AP05 cable must be used as the main cable. Be careful to select the “3151/AP05 + OBD01” cable in the software. If you have a tool with an OBD output (NAVIGATOR NANO series) or use a tool with a direct EOBD cable, you can connect the terminal cable directly, without using any adapter. In this case, only select the cable “OBD01” in the software.
