Common Troubleshooting
a.
Such failures as inaccuracy indication, out-operation of indicator, on the fly of large and small summation meters
(mechanical wheel drive excluded) or incomplete liquid crystal display are caused by the interior failures of the
instrument, therefore, these failures, once occur, should be judged according to the instrument interior failures, and
change the combination instrument directly.
b.
In case both the large and small summation meter and the indicator of electronic odometer are on the fly, such failures
can be removed by disassembling the speed sensor from the whole vehicle first, then connecting the sensor and
combination instruments as shown in the drawing.
Then, open the power supply and run the rotors quickly to observe the indicator variation of odometer.
the odometer indicator
should be no less than 40Km/
h variation in speed under
common condition when
running the rotors,
otherwise,
change with the good sensor

c.
The inaccuracy display of tachometer is usually caused by the interior failures of tachometer, in such situation,
change the combination directly. As for the good-bad shift or out-operation of tachometer, the failures can be judged
according to the following approaches:
1)
Start the vehicle, then check the voltage of signal input of tachometer (wire harness with multi-meter, the
voltage should be 6 V or so.
2)
In case there is no signal voltage, check the power supply system of the whole vehicle to remove the failures
in circuit.
3)
The plugs of wire harness is only allowed to be inserted in the combination instruments under the condition
that the signal voltage is normal, and the instrument is in normal operation.
4)
Where the instrument is in abnormal operation, such trouble is caused by the failure of combination
instruments, in such case, change the combination instrument directly.
d.
Troubles of fuel gauge and water thermometer
1)
In case the instrument indicator points to the large number after it is powered, disconnect the sensor from the
plugging elements of wire harness before judging such kinds of troubles, if the indicator is still at large number,
it can be make a judgment that the trouble is caused by the interior failure of instrument, in such case, change
the combination instrument directly; if the indicator returns to the small number, according to which it can be
judged that the trouble is caused by the sensor failure, therefore, change the sensor directly.
2)
where the instrument indicator stands still, such trouble may be caused by three causes probably, interior failure
of sensor, plugging elements of wire harness or interior failure of instrument; the inspection may be conducted
according to the following approaches: disconnect the plugging elements of wire harness from that of sensor,
grounding the wire at the sensor end; in such condition, the indicator should move upwardly to the largest
number; if such phenomena occurs, it can show the trouble is caused by the interior failure of sensor, in such
case, change the sensor directly; if the instrument indicator is still immobilized after it is powered, it can be
judged that the trouble is caused by the interior failure of instrument under the condition that the wire harness
and plugging elements are normal, in such case, change the combination instrument directly.

Inspection on Common Trouble
Failure Judgment Methods
No backup radar display (no
system start notification when
the reverse gear is engaged)
Check whether the plugging elements of power supply
of back up radar control box are in well connection as
shown in drawing H in next page.(when the reverse
gear is engaged, touch the detector, if there is vibration,
which shows the detector is powered.
Check whether the wire harness of inner mirror in
electric room and that on the top of body are in well
connection as shown in the drawing A in next page
Check whether the wire harness of back up radar
control box is well connected with that of chassis
and that on the top of body.
Rotate the vehicle key to the ACC position and
engage the reverse gear, then measure to see whether
the back up power supply reaches to 12 V with the
multi-meter of 50 V of voltage, refer to the
red
and black
positions shown in the drawing in next
page.
If the voltage reaches 12 V, change the backup
radar control box in trial firstly, then the inner
mirror in electric room, finally change the roof
wire harness and the chassis.
No backup radar display (but
there is start notification when
the reverse gear is engaged)
remark: such trouble occur
under the blocking condition.
Check whether the power supply of back up radar
is well located, see the red and position in the
drawing of next page.
Check and align the plugging element.
Poor properties of ultrasonic wave
Change the ultrasonic detector heads.
Continuous back up radar red
lamp alarming (remark: there
is no obstacle within 0.5 m away
from the detector head)
Check whether the detectors in the two circuit of
back up radar control box is well plugged, see the
marked positions F, G in the drawing of next page.
Check and well connect those plugging elements
Poor connection of the left/right ultrasonic detector head
Poor performance of back up radar control box.
Check and well connect those plugging elements
Change the ultrasonic detector head
Change the back up radar control box.

The detector head doesn
t work
Change the detector head
There is dirt on detector head
Clean the detector head
Rear standby tire inspection
1. engage the reverse gear for five times repeatedly within ten seconds at the spacious place so that the red
lamp on the screen flash three times, the system will automatically remember the standby tire status.
2. When the body height varies or the stand by tire is opened, make a new inspection for the rear stand by
tire to ensure the backup radar in normal operation.
