Cheapest tool is OBD2 dongle ($10) and phone app, like Torque Pro, Dr Prius, etc. Carista has excellent reviews.
If you really must have ABS/brake codes access, you will need CAN BUS compatible scanner and then you start looking into hundreds. Even with that, they will not be hybrid specific.
Also, to really get into innards of hybrid vehicle, you'll need a high end scanner that has access to proprietary codes. Thousands.
