How to Reset the ECM

You can reset the ECM in either of two ways:
- Use the OBD II scan tool or Honda PGM Tester to clear the ECM's memory. See the OBD II scan tool or Honda PGM Tester user's manuals for specific instructions.




- Turn the ignition switch OFF, and remove the No.18 (7.5 A) fuse (A) from the under-dash fuse/relay box (B) for 10 seconds.
