Connecting on /dev/cu.vLinkerMC via elm327, target 0xD5 source 0xF5, slow init...

Connection failed after 1 attempt(s): adapter reported 'BUS INIT: ...OK\rNO DATA' for 81

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.
