Electric Power Steering System
8-7
Fault alarm and protection function
In order to ensure
the EPS system can supply a
long life of reliability, a variety of detection and
alarm functions are set in the ECU software
program. Once a fault has been checked on the
EPS system, the UTV can accurately shutdown
the EPS system.
With the EPS
system shut down, the UTV
will be able to continue to complete the
steering function through the mechanical
structure of the steering system. However,
at this time the driver will feel the turning
resistance increase. You can continue
your driving of the UTV only it will take
greater force to operate the steering
system.
DANGER
When the meter indicates a malfunction of the
EPS system or when the driver finds the EPS
system operation abnormal, please do some
steps as below
：
Stop vehicles immediately, Shut off the main
switch, open the front panel’s repair cover,
and pull up the outlet which power supply for
EPS system (See page12-3)
Drive the UTV to dealer by lower velocity
and repair the EPS system.
EPS SYSTEM’S INSPECTION,
MAINTENANCE, REPAIR
：
The EPS system has already been inspected by
strict quality restriction before delivery, so it has
high reliability.
But if there is no inspection or maintenance as
stated time period during in use of EPS, it may
cause the EPS system to work abnormally or
spare parts in EPS system to be damaged
abnormally.
When the EPS system works wrong or gets a
malfunction, the malfunction warning and fault
code will be indicated on meter.
■
Malfunction assortment
：
During long periods of continuous fast
steering,
especially
when
ambient
temperature is very high, it may cause the
ECU to radiate a high temperature, and at
this time the ECU can get, through detection
temperature sensor’s, a signal to issue an
ECU over-heating failure warning fault code
to the meter. Meanwhile, EPS system fault
indicator light is on.
When ECU detected 1# steering torque
sensor or 2# steering torque sensor had
fault, then it will indicate
1#
steering torque
sensor fault or
2#
steering torque sensor
fault code to dash board.
Meanwhile, EPS system fault indicator light
is on.
When ECU detected the storage battery’s
voltage is lower than 9VDC through sensor,
it will indicate the fault code of storage
battery voltage low to dash board.
