Toyota Mechanic: Dan, ASE Master Technician replied 3 months ago

You need a higher end shop quality scan tool to get the codes. The scan tools at autozone will only read Engine and transmission codes. You have a code in the hybrid drive system that the autozone scan tool cannot retrieve.

A Toyota dealer is needed to get the codes to properly diagnose the hybrid system. This could be caused by the drive motor, high voltage battery, inverter or the system may need an update. Without proper tools to diagnose there is really no way to be sure.

Please let me know if you have any more questions.
