  2007 Toyota Highlander Hybrid Vehicle (HV) & Lexus RX400h Air Fuel (A/F) Sensor Monitor Readiness Shows Incomplete
  AF Monitor Incomplete_SSC F0P - FLD.docx
  A software error in the subject vehicles will prevent the readiness indicator for Air Fuel (A/F) sensor monitor from setting, possibly preventing the vehicle from passing an OBD based inspection due to the lack of adequate system readiness. However, the monitor does function, and will detect a malfunction if one exists and illuminate the Malfunction Indicator Lamp (MIL).

Toyota has developed new engine control software logic to prevent this condition from occurring (the oxygen sensor readiness will set to complete once the required A/F and rear O2 sensor monitors run and complete). This condition will be corrected by Toyota Special Service Campaign (SSC) F0P with Toyota TSB T-SB-0042-15 and Lexus SSC FLD with TSB L-SB-0027-15 at no charge to owners. For California owners, the Department of Motor Vehicle (DMV) Registration Renewal/Recall Tie-in Program applies.

Please direct any questions or concerns about the contents of this letter to Toyota/Lexus Techinfo Support, I & M Programs Administrator at (877) 762-7666.
