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.

Vehicle speed signal error (test mode dtc)
Description
The tire pressure warning ecu receives a speed signal from the combination
meter. This dtc is stored
upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20
km/h) is detected for 3
seconds or more. The dtc is output only in test mode.
