HINT:
- If the power steering assist stops, the EPS warning light comes on (red).
- If the amount of power assist is reduced, the EPS warning light comes
on (yellow) and a vibration or sound may occur.
- 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 being 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 when the steering
wheel is not turned for approximately 10 minutes with the engine running.
- If the battery is not sufficiently charged or the voltage decreases
temporarily, the amount of power assist will be reduced and the EPS warning
light will come on. In such cases, the amount of power assist returns to
normal when the battery voltage recovers.
