NOTE:
- During the procedure, do not turn the ignition switch to ACC (I) or LOCK (0).
- All readiness codes are cleared when the battery is disconnected, if DTCs have been cleared, or if the PCM is reset with the HDS.
- Low ambient temperatures or excessive stop-and-go traffic may increase the drive time needed to switch the readiness code from incomplete to complete.
- The readiness code will not switch to complete until all the enable criteria are met.
- If a fault in the secondary HO2S system caused the MIL to come on, the readiness code cannot be set to complete until you correct the fault.
