RE: SCR again...a new code (08-02-2023 )pgls651 Wrote: Cummins ISX 15 cm2350. Hit the derate with a code I haven't seen before. 1682- Aftertreatment Diesel Exhaust Fluid Dosing Unit Input lines-Condition Exists. just a guess, but pull the def lines and make sure they aren't clogged up, like Bengy88 said. Did you look up that code on Quickserv and follow the troubleshooting steps? also, wouldn't hurt to check the wiring for the DEF pump and such. Dunno about the 2350, but my 2250 has relays and fuses for that inside my battery box and I think it's controlled by the DCU which is also (on my truck) located near the battery box under the cab. Those DEF lines, and the tank too, all have heater elements that work to keep the DEF from freezing. User's Signature: "...And as we wind on down the road, Our Shadows taller than our Soul..." | |||
