The Aladdin monitoring system on my 2006 Monterey HAD been working reasonably well...until yesterday!!! For some reason, the system had a melt-down while we remained parked for the winter...ie. we've been parked for 2 weeks and the system has worked fine until yesterday so whatever the failure, it is unlikely related to any travel-related vibrations.
The red lights on both joysticks are lit but with the engine off, I can't get anything to display on the monitor screen by moving either of them. With the engine running, the screen lights up, the rear-view camera display works with the trans in reverse but neither of the joysticks allow me to scroll anywhere to monitor any of the functions. When I tried to assess the holding tank status on the gauge mounted in the service bay, the three indicators jumped from top to bottom for a few seconds and then switched to blinking erratically. I've checked the connections at the four interface modules I could find (DC, ATS, Tank and Temp/Compass) and they all seemed to be OK. I also check the connection at the J1939 Bridge box and it seemed to be OK.
From what others have said on this forum, I thought the root cause of my problem could be joystick related but it seems unlikely that both joysticks would fail at the same time.
Any thoughts from the Aladdin experts would be helpful.
