Connecting on /dev/cu.vLinkerMC via elm327, target 0xD5 source 0xF5, slow init... Connection failed after 1 attempt(s): could not open /dev/cu.vLinkerMC: [Errno 2] could not open port /dev/cu.vLinkerMC: [Errno 2] No such file or directory: '/dev/cu.vLinkerMC' Things to check, in order: 1. Ignition on, engine off. The ECU sleeps otherwise. 2. Diagnostic connector pinout -- confirm before suspecting anything else. 3. Try --init slow (5-baud) if fast init times out. 4. If retries didn't help, the ignition may need a real power cycle -- turn it off, wait a few seconds, back on, and re-run. 5. On an ELM327 clone, KWP support is often broken; try the KKL cable.
