Inspection Procedure

WARNING: This page is about a different car, the 2011 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When the power management control ECU is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes the on (IG) mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
