For the purpose of getting air on the system to raise the truck up enough for me to crawl under it. (Im a car hauler so my ground clearance is very tough for a bigger guy like myself) So upon starting the truck, i noticed the once solid and then flashing red light on the def gauge was no longer active.
I hooked up insite. All faults were inactive.
Good on one hand, frightful on the other.
Is it true everything is functioning (POSITIVE) or is it a False-Positive and as soon as I get up to highway speed and everything at full run operating temperature it’s going to show itself again?
Can I know before I go?
So, stupid question, but did you fill up on DEF while at the fuel island? I ask because that red light on the DEF gauge usually warms of low fluid level. The derate could have simply been due to being too low on DEF.
As for the SCR code, 3567, I used to get that once or twice a day. Usually I would just hook up insite and clear the codes once or twice a day. That resets the counter which resulted in the 3712 code. If like me your 3567 was intermittent then you can go weeks just by occasionally clearing the codes. If the 3567 has a high number of occurrences then you'll need to stop more often to clear them.
Either way you should be able to get home, stopping as needed to clear the codes.
I initially thought the same thing “low def” but i had filled up my def less than 600 miles. Maybe a bad level sensor? To answer your question though, yes i filled it up at the fuel island (just over 5 gallons) but the flashing red light in the def gauge was still flashing AND i was at a full derate so if that was the problem was their a delay due in the reset because it had already gone so far? So many unanswered questions and possibilities. But yes that what it seemed like was happening was it sensed a low def Level and light goes red. Continues sensing low level light starts flashing (HEY IDIOT IM ABOUT TO SHUT YOU DOWN TO 5mph) and that’s what happened.
