Inspection Procedure

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When replacing the ID code box (immobiliser code ECU) or power management control ECU, refer to Registration. Refer to REGISTRATION [08/2013 - ] .
  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".

HINT: 

When DTC B279A and a certification ECU (smart key ECU assembly) DTC are output simultaneously, first perform troubleshooting for the certification ECU (smart key ECU assembly) DTC.
