Stop Engine light- comes on briefly only up hills

January 21, 2015, 10:11:46 pm

Subject basically tells it all. Engine oil was just topped off, and so was coolant. Checked trans (has transynd) with shift pad and indicates Low 1 quart. It happened at various loads, but always up hill. Usually only came on long enough to read it, maybe 5 seconds at the longest. This started happening occasionally on our way back from Canada and has gotten way more frequent on our current trip. The hydraulic oil is at the add mark when checked while cold... I didn't have any 15w40 on hand. I am going to see if they have some at the travel center here at the Golden Acorn casino where we are overnighting on our way to "Q". Anyone know how many quarts down the hydraulic oil is when it reaches the add mark? More importantly, could that cause the stop engine light to come on if going uphill gives a lower reading, assuming it has a level sensor?
Any input is welcome. This is not a relaxing scenario!!!

Checked the quickmart and they do have Rotella T 15w40, but are out of the Delo 400. Should be compatible, I would think. But hydraulics other thank brake fluid is new for me. it looks from Barry B's site that it just uses 15w40 engine oil...
Thanks, Don

Don,
Your hyd. tank don't have a level sensor in it. It only has a sight glass and dip stick. Your alarm is more likely tied to a sensor starting to fail on the engine, like the engine temp or one side of your engine position sensor. I think that your 8.3 is new enough to have the double sided engine position sensor. Have you checked & cleaned all the electrical plugs on your engine for yuck? These are just some random thoughts. Yes engine oil is what came in the hyd system. On a side note the filters have had a part number change the old number was Nelson 84101B and after Fleetguard took over they changed the number to 87610A, or that is the number this week for the case of filters I just got.

Don,

One other random thought. If this occurs only starting a pull up a grade you may have a motor mount giving up. This could cause the engine to move too much during torque up thus pulling on a sensor wire giving you an intermittent alarm.

Probably not your problem.... But on a previous brand of motorhome we had this same trouble. And no one could find the solution. Then on our way to Valdez, two diesel mechanics stopped to help us stranded on an uphill stretch. They found an electrical wire to the engine shutoff valve had the insulation worn through and was grounding completely now instead on intermittently. Seven inches of electrical tape fixed the trouble temporarily. Later, when we encountered these guys again in a restuarant, we bought their dinner. (They would not take any payment. The next day they gave us a tour of the power plant for electricity in Valdez. Two WWII submarine engines and a standby jet engine.)

Thanks for the ideas guys... Keep the suggestions comming.
The Silverleaf diagnostics window shows the following faults on the last occasion yesterday, and previously when we were on our way back from Canada. It has been the same each time I have opened the diagnostics window, except for the dates and times;
Cummins Fault Codes 12/8/14

I've done some searching on the Internet, but I've yet to find what system these codes are referring to. Anybody else have any insight? If I knew which sensor or system defaults are referring to, it would definitely help narrow the scope of my diagnostic process.

From some quick looks around as well, that may be a fuel injector pump warning (1077) ...

If the pump is getting weak it may not be able to deliver the fuel pressure that you need when under load, such as going uphill.

You may find there is a small leak somewhere as well.

Here is the only thing I've found .. does not look like the VmsPC gives the Cummins fault code, but using the other codes you may be able to trace it down.

Fault Code: 329
PID: S233
SPN: 1077
FMI: 12
LAMP: None
SRT: Engine ECM has detected an overpumping malfunction in the Cummins accumulator pump system (CAPS) pump.Fault Code 329 can result due to one or more of the following:

Other fault codes that are caused by bad grounds.
High fuel inlet restrictions and/or air in the fuel can set the fault code.
Fuel that does not meet Fuels for Cummins Engines, criteria, specifically density and viscosity, has also been know to set fault code 329.
High fuel inlet temperatures can also set fault code 329. Fuel temperatures at the inlet to the gear pump should not exceed 60°C [140°F] on ISC
This fault code could also be caused by a fuel leak in the sealing plate between the injection control valve and the distributor. The injection control valve module should be replaced if a fuel leak in the sealing plate has been identified.
Fault Code 329 can be caused by broken internal injection control valve components and/or by poor lubricity fuel which scuffed the internal components of the injection control valve.

Result: Low power; possible engine shutdown.

Thanks for the research Steve, I am hoping that it doesn't have anything to do with the internal components of the CAPS pump. I had earlier check engine lights which I was able to reset by disconnecting the chassis battery, one of which was a lift pump unknown failure, and another stop engine light which came on and went off again after about thirty seconds or so. The later would happen only once and within the first 5 or 10 minutes of travel. It was, as I think about it now, under similar circumstances: under load, such as merging on to the freeway, and as i recall, usually up hill. It showed up as something like "manifold grid heater- over temperature". Not sure about the verbiage, but it was words to that effect. Anyway, some reading I did at the time, stated that the grid heater, and lift pump shared a ground connection. I just need to find where that is so I can check it...
That would be my preferred fix!

I hope it is a ground as well, and that is one of the first things the diagnostic list mentions as well. I'd also check the data connection between the ECM and the Fuel Pump, make sure the connection at the fuel pump is clean and secure. Keep us informed, its always fun chasing codes, but at least they give some someplace to start.

@Don While at Q Pierce loaned me his ProLink-9000 along with the manual. Reading the manual I found that there are several different types of output messages. MIDs, PIDs, SIDs & FMIs.

Message Identifiers

Program Identifiers

Subsystem Identifiers

Failure Mode Identifiers

Here is a link to a PDF that lists the SAE standard codes that are displayed by the ProLink. http://brianforte.net/linked/sae-mid-sid-pid.pdf

I do remember reading that the greater than 200 codes are sometimes reserved for manufactures to use as needed but this PDF shows several codes in the 200 range. ie: your SID 233 shows as "Controller #2" no idea what that means.

I need to get one of these things! I have done a bit of research, but still not sure what I would need to buy to be able to get access to the Cummins holy grail. Thanks for the link to the PDF.
