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 auxiliary 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 auxiliary battery voltage recovers.
