Common faults and troubleshooting 
methods for the hazard warning lamp 
switch  

1.  Common fault: Button stuck or having 

abnormal noise. 

Cause analysis: The motion and guide position of 
the switch is not lubricated by grease, making the 
button’s guide rib rubbing and interfering with the 
guide slot of the casing.  

Troubleshooting method: Apply proper amount of 
grease around the button’s guide rib.  

2.  Common fault: It is difficult to assemble the 

connector.  

Cause analysis: The pin is warped; there are fins 
and burrs on the connector. 

Troubleshooting method: Remove the fins and 
burrs; use tool to correct the pin and recheck it 
with the special gauge.  

3.  Common fault: The backlight symbol has 

nonuniform light transmission; there is 
shadow and light leak.  

Cause analysis:  

a.  The connector LED is not welded at the 

center of the switch symbol.  

b.  The improper setting of the parameters of 

CNC engraving machine make the backlight 
symbol coating incompletely carved.  

Troubleshooting method:  

a.  Adjust the LED position to have it located 

below the symbol’s center. 

b.  Replace the switch button. 

Removal/Installation of Left Switch Block 

1.  Disconnect the negative cable of the battery. 

2.  Open the left storage box.
