Just started working for a new company, was put into a truck that had a CEL on and when I asked they said “do a passive regen, it’ll go away” well anytime I need to do a regen, I have to park and regen nearly every hour because my passive regen isn’t working. I’m trying to find an answer or at least someone else whose experienced this (also seeking mechanical help and advice too!) I’m in a 2018 Kenworth T680 automatic.
Update: check engine is on along with the MIL, we have a blinking regen light and the diagnostics says “derate due to engine filter full” but not even 40 minutes ago ran a full regen. And while running a new regen, it said to regen while I was already doing a regen... Any help would be appreciated!
CEL on truck won’t passive regen, only parked
