BE-38Body Electric System
Backup Radar System
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 workChange the detector head
There is dirt on detector headClean the detector head
Rear standby tire inspection1. 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.

Remark: the right and left LED display the direction and distance of obstacle respectively for driver
reference.If the voltage fails to reach 12 v, check the power
supply system of original vehicle
s large wires
to restore the voltage to 12 V.
