ISB fault 1682, SPN 3362, FMI 31 check engine codes
My check engine light came on this weekend after bringing my 2012 Journey home from storage. LCD on Dash indicated SPN 3362, FMI31.
while doing some Google searches, this is related to Fault Code 1682. "Aftertreatment DEF Dosing Unit Input Lines - Condition Exists. An error has been detected by the aftertreatment DEF dosing unit."
Just curious if others have had issues with the DEF system.
Dropped unit off at local Freightliner shop this morning.
