No. 250Door lock is not self-locked after driving 30 feet   

Malfunction Cause 

Solution 

Malfunction of fuse for 
centralized controller   

Check fuse of centralized controller for conducting; if it’s broken, the fuse of 
centralized controller should be replaced;   

Internal malfunction of 
centralized controller   

Check centralized controller for normal working; if it’s abnormal, the 
centralized controller assembly should be replaced;   

 
Malfunction of speed sensor   

Check normal function of speedometer and then check if the signal is 
transferred to centralized controller; if it’s not working normally, the speed 
sensor should be replaced;   

Locking latch for left-front door 
in poor operation 

Check, repair or replace locking latch for left-front door;   

Failure of speedometer 
indication  

Check why the speedometer indicates abnormally, or replace combined 
instrument;  

Door lock is not 
self-locked after 
driving 30 feet   

 
Malfunction of harness   

Check loop of centralized controller and relative central control locking; if it’s 
abnormal, the loop should be checked and repaired;

No. 251 Failure of central control locking while driving   

Malfunction Cause 

Solution 

1. Check if the lockup unit is firm and free of dropping-of; if not, it should 
be repaired; 

 

2. Check the lockup unit for blocking; it should be moved freely during 
normal working; if it’s blocked, the lockup unit should be replaced;   

1. Malfunction of lockup unit 

3. Check motor of lockup unit and measure its resistance for short-circuit 
or break; if so, it should be replaced;   

4. Check fuse of central control for break; if so, the loop should be 
checked for short-circuit, grounding and over-current; if so, the fuse 
should be replaced after repairing;   

2. Malfunction of circuit   

5. Check connector for loosing or dropping-off; if so, it should be 
repaired;  

Failure of central control 
either by manual control 
or by remote control   

3. Centralized controller   

6. Centralized controller is damaged internally; the centralized controller 
assembly should be replaced;   

 

 

Failure of central control locking while driving

No. 252 Flashing CGQ alarm indicator for speedometer   

Malfunction Cause 

Solution 

1. Check if the resistance of sensor is in normal range; replace it if 
necessary;  

2. Lift front wheels and shift the gear; check speed sensor for signal; 
replace it if necessary;   

1. Malfunction of speed sensor 

3. Check speed sensor for dropping-off or poor contact; repair it if 
necessary;  

2. Malfunction of drive assembly 
for speedometer   

Check speedometer for blocking or damage, otherwise replace it if 
necessary;  

2. Malfunction of circuit   

4. Check sensor combined instrument loop and all connectors for 
short-circuit, open circuit or poor contact; otherwise repair it if necessary; 

Flashing CGQ 
alarm indicator for 
speedometer during 
driving   

3. Malfunction of combined 
instrument  

Check internal PCB of combined instrument for fault; otherwise replace 
it if necessary;
