Trouble Shoot
1. If only one pc ambient light color not synchronize: check the 4 cables if loose; the cable soldering sequence if same as other light, if PIN is plugged into hole well, if PIN is broken
2. If all lights not work, use multimeter to check if the module has power, if yes, pull out the module cable, after one minutes, re-plug it again
3. Light color not changed or not same as the menu, do the same thing as step 2
4. If the light is dark, check light case, light head if loose, or check if the light head is put to correction position
5. 5, If all lights not work, check if CAN cable is connect wrong, use multimeter to check the 2 CAN cables if there’s power to module （CAN cable is white and yellow cable)
