How to Set Readiness Codes: Procedure: Notes
- Connect the HDS or a scan tool to the vehicle's data link connector (DLC). Bring up the tool's generic OBD II mode (scan tool only).
- Start the engine, and let it idle for 1 minute. The readiness code should switch from incomplete to complete.
- If the readiness code is still set to incomplete, check for a Temporary DTC. If there is no DTC, repeat the procedure.
