5.5 Electric Power Steering (EPS) System
The EPS is a power steering system directly
relying on motor to provide auxiliary torque. EPS is
mainly composed of torque sensor, motor,
decelerating mechanism and electric steering
control unit (ECU).
By detecting the driver’s torque input and
signals of whole car conditions, for example, car
speed and engine speed, the ECU controls the
torque output of the assist motor in real-time
manner, so as to realize the best steering assist,
ensure flexibility at low speed and stability at high
speed, and improve driving experience and car
safety.
Steering Mode*
There are “Standard” and “Sport” steering
modes. You may have to steer harder with sport
mode. “Standard” is the default mode of the system.
You can set the steering mode in audio system.
=>Refer to Page 203
ECU is equipped with warning light alarm and
text alarm. When the Start or Ignition switch is at
"ON" position, the indicator light of the electric
power steering (EPS) system will be on for several
seconds, the EPS control unit will finish the self-
inspection, and then the indicator light will be off,
which indicates that the EPS system works
normally.
If the indicator light goes on after start of the
engine or during driving, there is fault in the EPS
system, and relevant text alarm will be shown on
the instrument cluster display.
When fault occurs in the EPS system, park the
car in a safe place, turn off the engine and then
start the engine again. If the light is still on after re-
start or during driving, please go to your GAC
MOTOR dealer timely for repair.
Electric Steering Column Lock (Apply to Models
with Start Switch)
When the Start switch is switched from "OFF"
position to "ACC" or "ON" position, the electric
steering column lock will unlock automatically.
When the Start switch is switched from "ACC"
or "ON" position to "OFF" position and the door on
driver’s side is open, the electric steering column
lock will lock automatically.
