Toyota RAV4 (XA40) 2013-2018 Service Manual: Fail-safe chart
If a problem occurs in the electric power steering system, the p/s warning light will come on in the combination meter and steering power assist will be stopped, fixed at a particular point, or decreased simultaneously to protect the system.
Hint:
The amount of power assist may be decreased to prevent the motor and ecus from overheating if the steering wheel is continuously turned when the vehicle is either stopped or driven at a low speed, or if the steering wheel is kept at either full lock position for a long time. In such cases, the amount of power assist returns to normal if the steering wheel is not turned for approximately 10 minutes with the engine idling.
