How to Troubleshoot Circuits at the ECM/PCM

  1. Gently slide the sharp tester probe (A) into the connector from wire side until it touches the end of the wire terminal.

  1. If you cannot get to the wire side of the connector or the wire side is sealed (A), disconnect the connector and probe the terminals (B) from the terminal side. Do not force the probe into the connector.

Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.

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.
