How to Substitute the ECM/PCM

  1. Remove the ECM/PCM from the vehicle.
  2. Install a known-good ECM/PCM in the vehicle.
  3. Rewrite the immobiliser code with the ECM/PCM replacement procedure on the Honda PGM Tester. It allows you to start the engine.
  4. After completing your tests, reinstall the original ECM/PCM and rewrite the immobiliser code with the ECM/PCM replacement procedure on the Honda PGM Tester again.
