effectively detecting the reversing gear information and the like); 

2.  Connection error of reversing rearview camera wire harness; 

3.  During reversing, the system power end has no +12V voltage or the system power ground is 

not connected with the body ground well; 

4.  The transmission harness for the video signal output by the system is damaged (rearview 

system end has a signal and the non-core navigation end has no video signal), so that the 
signal is lost in the transmission process. 

11.13.6.10Possible reason of rear camera image-line resolution reduced (Definition reduced) 

1.  The camera lens surface is dirty (such as waterlogging, muddy water, oil and dust etc.). 

2.  When the camera is in the condition of low temperature (high temperature) for a long time, 

enter into the condition of high temperature (low temperature) suddenly; 

3.  Because the camera lens is damaged to human factors, the glass lens on the lens surface is 

damaged (with cracks). 

4.  On rain days, in heavy fog and at night (in the environment with insufficient light) 

11.13.6.11 Routing maintenance precaution of reverse rearview mirror camera 

1.  Ensure the normal use of the system and you need to clean the surface of the camera lens at 

regular intervals (it is recommended to wipe with dustless cloth dipped with alcohol). 

2.  To avoid the camera from being damaged due to external force, please do not impact the 

camera (particularly the lens) due to hard object. 

3.  In order to ensure that the definition of the camera is not affected, please do not scrap or 

scratch with sharp objects (hard object) or rub the surface of the lens. 

4.  When failing to troubleshoot through the method recommended in the manual, it is 

recommended to repair through professionals. 

5.  If the vehicle is lent to the other people for use, please inform the user these precautions.

Diagnostic steps: 

Note: Inhibit starting the vehicle when performing this inspection step; otherwise, the damage 
to the vehicle and personal injury may be caused! 

1 

Inspect whether the reversing lamp works? 

(a)    Rotated ignition switch to "ON" position. 

(b)  Place gearbox gear to "R" gear. 

(c)  Obverse whether reserving lamp lights up. 

Does the reversing lamp turn on normally? 

 

2 

Inspect whether the power and grounding of the parking radar control module are 
normal. 

 

(a)  Rotated ignition switch to "OFF" 

position. 

(b)  Disconnect parking motor control 

module harness connector SO32.

(c)  Rotated ignition switches to 

"ON" position. 

(d)  Place gearbox to "R" position. 

(e)  Measure resistance between 

parking radar wire harness 
connector SO32 terminal No. 1 
and reliable grounding. 

Standard voltage: 11-14 V 

(f)  Measure effective grounding 

resistance between parking radar 
wire harness connector SO32 
terminal No. 17 and vehicle 
body. 

Standard resistance: less than1 Ω 

Is measured value normal?

Repair the wire harness 

(a)  Repair open-circuit fault between parking radar control module wire harness connector SO32 

terminal No. 1 to reserving lamp, and fault between parking radar control module wire 
harness connector SO32 terminal No. 6 and effective grounding of vehicle body. 

(b)  Connect to parking motor control module harness connector SO32. 

(c)  Rotated ignition switch to "ON" position. 

(d)  Place gearbox to "R" position. 

Confirm whether the buzzer is normal. 

 

4 

Inspect whether the buzzer driving circuit is normal. 

 

(a)  Rotated ignition switch to "OFF" 

position. 

(b) Disconnect 

parking 

motor 

indicator harness connector IP10.

(c)  Disconnect the combination 

instrument p harness 
connectorIP01. 

(d)  Use multimeter to measure 

resistance between parking radar 
indicator lamp wire harness 
connector IP10 terminal No. 6 
and combined instrument wire 
harness connector IP01 terminal 
No. 7. 

Standard resistance: less than1 Ω 

Confirm whether the resistance 
conforms to standard value.
