check that the relay on the cab cable is pluged in and has a green light (it has a 4 square weather pack plug) this is what sends power to the modules when the monitor is powered up
I would check for the presence of the flashing LED on any other modules. Since you are using a Liquid Module you will also have either an Auxiliary Input Module OR the SC110 CAN switch box. They should have an indicator light themselves which should be flashing. This could be helpful for troubleshooting.
If the Auxiliary Input Module OR SC110 CAN switch box has a flashing indicator then the problem is likely in the CAN wiring to the Liquid Module. If no indicator LED is lit on the either of them then the problem is possibly the relay as mentioned above. The display and all Modules need to be able to communicate with each other. |
