4. Key tooth inspection
Check the broken or peeled spline teeth. The spline teeth may,
if only small part is peeled off, be repaired in the same way as
that for the gear teeth, and can be reused. In case the spline
tooth is broken, the spline must be abandoned. The contact
type of spline is not the same as that for gear; however, spline
that shows step sliding must be abandoned.

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.

Mount of bass speaker and VCD
(a) bass speaker
Connect the audio output wires of bass speaker with the sockets in bass speaker correspondingly according
to the wire color (red plugging element should be plugged in red socket, yellow plugging element in white
socket, the grounding wire (black), power wire (yellow) and signal wire (blue) should be fixed at the
corresponding positions (GND
12V
REM) on bass speaker tightly.
(b) multi-disc VCD
The feed cables of VCD main device should be connected as marked, when connecting the plugging element
of wire harness of video camera (CAM) with the plugs on main device (CAM), notice should be taken on the
two arrow marks so as to prevent the plugging element damage; The audio output wire plugging elements (red
and yellow plugs) of bass speaker should be connected with the red and white sockets of mainframe (AV OUT);
the plugging elements of TV receiving input wire of amplifier should be connected with either of the plugging
elements(AV AN) of the mainframe; the plugging element (black and white ACC) of anode wire of power
supply should be connected with the red socket (ACC) of mainframe wire harness; grounding wire plugging
element (black GND) should connect with the black socket of mainframe wire harness; the plugs of audio input
wire of deci-disc data converter should be connected with the red and white socket on mainframe according
to the plugs color (the plugs (red, white CD OUT) of audio input wire of eight-disc box should be connected
with the red, white socket (CD IN) on mainframe according to the plug color, the yellow power wire plugging
element (BATT) should be connected with the yellow power wire socket (BATT) on mainframe, the electric
aerial, plugging elements of control wire of function amplifier should be connected with the electric aerial
(CTL), socket of control line of function amplifier on mainframe. After completing the connection of plugging
elements, wrap the connecting position with adhesive strap in order to prevent those plugging elements from
peeling off, the plugging element of feed cable of TV receiving aerial can connect with any two of the four
holes on amplifier, meanwhile, turn on the switch (with a red indicating lamp) of amplifier when watching the
TV play. When mounting the VCD mainframe, push the wire harness innermost as can as possible so that there
is spacious room for mainframe, then push in the mainframe, notice should be taken not to damage the wire
harness. Fasten the mainframe to the degree that it cannot be pull out by hand after assembling, if it cannot be
clamped tightly, prize out the two clips on the inner sleeve, then fasten the mainframe, and mount on the
external decoration frame finally. When disassembling the mainframe, tear down the external decoration
frame first, then insert the special key into the open grooves at two sides to pull out the mainframe.Body Electric System
