Most 2013 and some 2014 NO fuel heater engaged

[TCDiesel]

Most 2013s and some 2014s do Not have the Heat elements engaged, I had problems with My fuel again form Holiday.

Here's some Quotes I Left at CF -12 rear filter plugged/gelled up , no run

--------------------------------------------------------------------------------

We'll ,I knew that filter would be trouble, If I did not install the auxiliary bypass Pumps/Filter the truck we be towed to Dealer, I drove it into the shop and Removed the Rear filter it was gummy, the front was good.

When I installed the auxiliary system I made plans to bypass that filter in the future, sometime today I will be installing the filter bypass for extreme cold, well -12 is not even cold.

This truck has Dual additional pumps with in heat filtration.
-----------------------------------------------------------------------

Yep... In most cases it works out, Stuff happens and I move on, This 2nd time with the worthless attitude Definitely terminates any future Business, I'm not going to extend any kindness to Holiday, They will just take advantage of it. My future purchase (Holiday) won't exceed 2 for 1 Donuts but that's going to be it.
---------------------------------------------------------------------------------

I know, The rep came right out and declare it was non-functional and we checked.. The tech manually engage the element and 0 volts, after the flash/Program it was working (Both)

Check out work order.

Trying very unsuccessfully to not sound like a dumbass, but should I go to the dealer to have this checked out or wait till I can't start my truck? It was down to 10 here yesterday.

 

[TCDiesel]

Yes, print out the attachment and schedule appointment ASAP.

 

[rrl989]

TCDiesel, thanks for the info. What would be a way to verify this on my driveway? I'm very familiar with the 2nd gens but a bit of a newby on these 4ths. Where are the fuel heaters, on the rear filter in the back?

Looks like problem identified yesterday. Have your dealer perform this Star Online case.

STAR Case
This document does not authorize warranty repairs. This communication documents a record of past experiences. STAR Center
Online does not provide any conclusions about what is wrong with the vehicle. Rather, it captures all previous cases known that appear
to be similar or related to the vehicle symptom / condition. You are the expert, and you are responsible for deciding on the appropriate
course of action.
Chrysler Group LLC Contact the STAR Center for assistance if no solution is found Version 5/23/13
Case Number: S1314000010
Release Date: 12/13/2013
Symptom/Vehicle Issue:
2013 - 2014 Ram Trucks equipped with the 6.7 L Cummins Turbo diesel engines with fuel related
faults and/or hard, no start or start/stall condition due to fuel gelling in cold ambient temperatures.
Discussion:
Ram Trucks equipped with a 6.7L Cummins Turbo Diesel exhibiting the above concerns have a
condition that will cause the chassis mounted fuel filter heater not to function. The condition is due to
a configuration setting in the Body Control Module (BCM) that does feed power to the fuel heater
relay for the chassis mounted fuel filter only. The engine mounted filter fuel heater is operating
properly.
Vehicles that exhibit the issue as described in the Symptom/Vehicle Issue described above;
generate and print a Configuration Report and then perform a vehicle reconfiguration to resolve the
issue. Perform a reconfiguration as follows;
 Generate and print a Configuration Report
 From Vehicle View (Topology) screen, select BCM
 Select Misc. Functions
 Select Vehicle Reconfiguration
Validate proper heater operation by testing for battery voltage at the heater connections with the
ignition switch is in the Run position.

So if I disconnect the chassis filter heater connector under the truck and I have 12 volts with the key in run as in the last sentence of Sag2's post my truck is OK right?

So if I disconnect the chassis filter heater connector under the truck and I have 12 volts wit the key in run as in the last sentence of Sag2's post my truck is OK right?

That is correct.

 

[RikDavis]

So if I disconnect the chassis filter heater connector under the truck and I have 12 volts wit the key in run as in the last sentence of Sag2's post my truck is OK right?

Is there a temperature above which no voltage would be expected at the connector. In other words must this test be done when it is cold?

 

[Kirwin]

Excellent question. Sag2, does the PCM tell the BCM to energize the relay when ambient temperature is at or less than a pre determined value?

 

[MelvinPierce]

Easy way. Plug it in for a couple hours when it is cold out. Then, start it, and switch your evic screen to show water temp. It was zero a couple days ago, and water temp was at 60F. Heater was working!

 

[TCDiesel]

We are talking about the frame mounted Filter heater, Two ways to check it ,1st manually with correct device, second check the voltage when (My guess) 30* or less.

The old canister engine mounted filter turn on at 30* and of at 70*

We'll Both of Mine were NOT working correctly on My 13, the engine was on correctly but off to soon, the rear was NOT working altogether. I did check them both before I left to The Rockies yesterday.

Yep. My mistake.

 

[Dieselnerd]

Any idea of the production dates of the 2014's that might be affected by the heater problem?

I'm just wondering when the configuration update took place. I see the date 5/23/2013 in the STAR post by Sag2. (Contact the STAR Center for assistance if no solution is found Version 5/23/13) Are the trucks built after that date OK?

Mine was built in mid-September and I'm getting ready for a big trip. All hitched up to my fifth wheel and too cold and snowy to crawl around underneath. Any info would be appreciated.

Wow, that sucks!

Sounds like the fuel could use a little more winterization as well since you shouldn't have to rely on the fuel heater at -12°F.

The Rep Form Holiday is big liar, The Test sample they remove form My Auxiliary Tank was clouding up when I and the Guy they sent out pull the sample, the Truck was in My Garage heat at 70* We could see the problem with our eye's. They Claimed it was good to -27 BIG Lie. I'm Not done with Holiday, with the incident form June and Now this. Holiday did emergency Drops at all corporate Stores Knowing the Dept of commerce in MN was coming to dip the stations tanks after I filed the complaint.

Next OCT 1 2014 I will be personally get samples form the 5 corporate stores around Me, I will test them and if they are NOT -10 the commerce Dept will be taking samples OCT 2 2014, if they don't meet the -10 its goona be $$$$$ in fines.

I'm in West Yellow until 2-4-14. I have already spoke to the Powers in MN to force station owners and the law to require better water/contaminates filtering at the Pump. the National convention for the fed level Meets in Albuquerque NM on 1-18-14

I've said this many times the system they use to rate filters is flawed and if these filters did what they (Most) claimed I would be out of business .............

 

[Kirwin]

TCDiesel, when you say you checked the OEM fuel filter heaters, exactly what did you test? That there was 12 Volts available at the body harness connector for each heater at the filter head harness connection? Or are you stating that the calibration of the thermistor/sensor in the filter head that contols the actual curent to the heating element was incorrect and the heater, although it had power at the harness connector at the filter head, did not come on even though it was cold enough that it should be on? Obvioulsy if the BCM does not know that there is a fuel heater connected to it, the system won't work. Thus I was thinking that the Chrysler case you cite above, the BCM was not powering the fuel heater relay and that both heaters were connected to the output of this relay. It would seem to me that if there was a fuel heater relay, like in the past trucks, that the chassis mounted filter heater supply wire would be spliced in and would power both heaters from a single relay. I (mistakenly?) assumed that the "configuration error" that you discussed above was related to the addition of the chassis mounted filter assembly and that the BCM had not beeen updated to enable the power output to the fuel heater relay that allows power to the heater/thermistor assembly in both the normal engine mounted filter head and the chassis mounted filter head. Since gas engines don't have a fuel heater that I'm aware of, I thought that this may be the acutal issue that Chrysler's master computer didn't know that the diesel trucks configuration needed to be updated and when they added the second filter they added a whole new relay setup and thus they needed to enable another relay driver in the BCM to reflect this for the chassis mounted filter head heater. I will look in my service manual CD tonight to see if it has any insight on this, but, it's pretty useless when it comes to electrical things. It doesn't even have a good explanation of how the trailer tow wiring circuit is powered, so I'm not expecting any real answers on how the fule heaters are arranged. Hell of a thing, send that kind of money for a service manual and you don't get any wiring schematics, not even a generic one.
As a side note: If the fuel was gelled in the tank the truck won't run long even if the heaters are worknig correctly, gelled fuel will not make it through the filter on the bottom of the pump in the tank and the truck will die just as if the fuel filter is plugged. Ken Irwin

Just had my '14 3500 into the dealer today. I was going to ask about the frame mount filter heater not working, but they mentioned it first. They checked, and had to turn it "on".

They said RAM is telling them all the 13 and '14 trucks, up until just recently built, all have the same issue. The rear filter heater is not turned "on" at the factory, and need to be reconfigured to get it on. It is a software issue, no mechanical problem.

 

[CEppinger]

I think that mine has this also. Code P0087 (low rail pressure), drives fine for 10 miles(fuel already in the lines?) then starts to buck and stumble when trying to accelerate. I get fuel at the same place that I fill up the Jetta and no problems with it. It was towed to the dealer at noon, will update when I get the truck back.

Seems like it should be a recall issue then?

 

[MelvinPierce]

I would doubt a recall, as that is usually safety related. However, could well be TSB. For most owners, it is not a big deal. If you are not in cold enough temps to cause gelling, it is a non issue. Mine was not working, and the truck drove fine at -27F. However, I was running almost pure #1, so no gelling, so no heat needed. For most, the dealer will check when it goes in, and do the reconfigure to turn it on.

One drawback, manager said that the reconfigure would cause the transmission to start all over "relearning". And, I could tell the first shifts around town were a little jerky. I have had it before, and smooths out soon.
