Catalytic Converter Monitor and Readiness Code: Notes

NOTE:
  • During the procedure, do not turn the ignition switch to ACC (I) or to LOCK (0).
  • All readiness codes are cleared when the 12 volt 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.
