There is probably a fault in the wiring between the display screen and the control module or in the middle connector.
Check the left-hand picture signal. Check the cable between the control module terminal #A7 and display screen terminal #7.
Check the ground signal to left screen, that is, the cable between the control module #A8 and the screen #8.
Checking feed to screen
Check the supply to the display screen. Supply is carried via a cable between control module terminal #A6 and display screen terminal #6. The ground terminal is from control module terminal #A3 and display screen terminal #3.
Checking the lighting for the control module
If the surround lighting for the display screen does not function. Carry out the above checks on another cable.
Check the supply to the lighting. Check the cable between control module terminal #A10 and display screen terminal #10. The voltage must be approximately 10-14 V.
In addition check the power supply for the cable, the cable between control module terminal #A9 and display screen terminal #9. The resistance must be less than 1 Ω.
