When using a scan tool

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2005 Honda S2000, 2004 Honda S2000, 2003 Honda S2000, 2002 Honda S2000, and 2001 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect a scan tool to the vehicle's data link connector (DLC), and bring up the tool's generic OBD II mode.
  2. Start the engine.
  3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about 5 miles (8 km), the readiness code should switch from incomplete to complete.
  4. If the readiness code is still set to incomplete, check for a Temporary DTC. If there is no DTC, one or more of the enable criteria were probably not met; repeat the procedure.
