Not much you can do yourself without having diagnostic code information, you'll have to either go to a Toyota dealer or to a shop that has a diagnostic tool that can read code information from the engine computer as well as the hybrid system computers.

SOURCE: 2003 toyota prius hybrid while driving suddenly

Hi. When you have that particular light on, you need to get the power steering motor checked. This is not something that a non-Toyota service shop can check out. You need to take it to a Toyota dealer. They can check the steering motor system, and diagnose exactly what the issue is. Unfortunatly, there is no other way you can check it, as there is not "pump" on the stweering, it is actually a small motor that runs the steering.

You need a scan tool or a code reader to do it but,if the problem still exists then the lights will come back on.You need to retreive the troubles codes from the computer to see what area of the engine that problem exists and go from there.

2007 prius master warning light, (!), VSC and engine light on

The problem may be the check engine light only, whenever it turns on the master warning light may also turn on, if there is an autozone or similar autoparts place close by you can go there and they can diagnose the check engine light using their scantool, then you can reply here to me with the code numbers and I can help, the code numbers are important so please write them down.
