We are having similar issues. First time was about 1 am between Needles & Blythe CA on a 2 lane. Immediately pulled off on a leaning shoulder when lights came on. Checked temps with an IR gun. All were OK. Silverleaf showed low coolant level code as well as several real goofy codes like #18 injector problem etc. from about 8 months prior that I was completely unaware of. I thought low coolant level might have been because we were on a substantial slope, but sensor would have been on low side not high side of radiator tank. Restarted after 20 min rest & it ran fine rest of night. It happened 2-3 more times showing low coolant level error. Replaced sensor & thought I had it taken care of. Wrong! Took coach to S&S in El Paso. Tech downloaded DDEC to their system. Only errors showing were low coolant level errors. None of the goofy stuff on my Silverleaf. They suspect a problem in the harness but I was short on tome to get it done so we headed to CA for work. Has happened 3-4 more times, but now I just hit over-ride switch on dash & like magic everything resets & we continue on without missing a beat. I have scheduled it to go in to S&S to get a new harness or another sensor as soon as we get back from CA.
