Check that the LED diode for "SALOON" have a steady green light on both gates. 

If it doesn't work, try below:

1: Connect a gatecom cable directly between the PCB:s. If it works, then we know that the PCB:s is fine.
2: Check all connections. From PCB, down to MPB, between MBP:s and then to the second PCB. 
3: Change cable between the MPB:s. 
4: If it still doesn't work the cables inside MPB needs to be changed.
