How to Troubleshoot at the ECM

Special Tools Required

  • Test pin box (pin box 130 seem) 07XAZ-0010100
  • Test harness 070AZ-PLZE100

  1. In case you measured the standard voltage of ECM, remove a connector and use the Test pin box and Test harness.

  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.

Do not force the probe into the ECM connector.

How to Substitute the ECM

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