Just a follow up to Jun 18 post on "SDS" message on the EVIC, I kept running it around the local freeway in my burg, and after the countdown ran for 18 miles the Service Def message disappeared from the EVIC and now at 1500 miles has not returned.
Assuming there was a burp in the system,....... to kenb's above I had the same happen with DEF tank between 1/4 and 1/2 tank same message, stop the truck, wait for resets.. started it and it reported "empty tank", "stuck float assumed", filled it and its been fine....pinged Ram Cares on the Forum and the reply narrative was that the gauge reading near 1/4 and or above 1/4 tank is subjective to when the message will make its grand entrance in the EVIC...... and I take it as don't trust it below 1/2 tank and as many have said carry a couple gallons if towing far between possible DEF stations. Based on what Ram Cares said they "know" the reading is a generality and a Class Action would be as effective as trying to beat a rattlesnake to death with a twinkie...
