# Service bulletin 14\-001\-14 REV. A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10136985
- Published by NHTSA: 2018\-05\-21

## NHTSA's summary

Fuel Gelling in Cold Ambient Temperatures This bulletin involves reconfiguring the Body Control Module \(BCM\). Some customers may experience a Malfunction Indicator Lamp \(MIL\) due to fuel related Diagnostic Trouble Code \(DTC\) and/or may have a hard or no start condition due to fuel gelling in cold ambient temperatures \(20°F or \-7°C\) or below. DTC?s, such as P0087, P0191 or P026B \(or other DTC?s\) may have been set. Ram Trucks equipped with a 6.7L Cummins Turbo Diesel included on the RRT VIN list exhibiting the above concerns have a condition that will cause the frame mounted fuel filter heater not to function. The condition is due to a configuration setting in the Body Control Module \(BCM\). NOTE: The engine mounted fuel filter heater is operating properly.

Diagnosing A Urea Module That Is Exposed To Diesel Fuel This bulletin involves discussing what will happen to the rubber material used in the urea pump when exposed to diesel fuel. This unit is sometimes referred to as the Selective Catalyst Reductant \(SCR\) module or the Adblue Delivery Module \(ADM\). Units exposed to hydrocarbons have a particular failure mode, the rubber heater unit is crinkled and in some cases the metal heater protrudes through the rubber membrane. The rubber material used in this unit is designed to withstand Diesel Exhaust Fluid \(DEF\) only. Exposure to fluids that contain hydrocarbons \(i.e. diesel fuel\) will damage the unit beyond repair. Units returned that exhibit this failure mode will have warranty claims that are rejected. Units that exhibit this failure mode should be considered customer abuse and should not be covered under warranty. Use the Hydroscopic test paper \(P/N 223\-44\-863\) available through MoparEssentialTools.com to confirm exposure.
