Troubleshooting Red Check Engine Light and White Smoke

December 16, 2015, 06:42:56 pm

A friend of mine has a 2000 U320 with the 450HP Cummins engine. On a trip home he had the yellow check engine light come on. When he was almost home, the red check engine light came on, and he had white smoke come out of the exhaust. He checked the engine codes and got what he thinks was 707. Does anyone have any idea what that code means. His fuel filters are clear.

Ben,
Things that can cause the white smoke:
Coolant internal leaking into combustion chamber, no lights usually
ECU Voltage low, Yes a light
CAN Bus info incorrect due to crank & cam sensors out of time also low power.
You bet lights
All this is a guess, a Cummins Dist. would be my choice, not Honest Bob's fix it garage.

Good luck

Not seeing that code in my list (nor does the Google find it).

Red light skin s the stop engine light. First thing I would check is the coolant level. I don't have a 707 either

We have that list and did not see a 707 code either. I guess this might be a problem for Cummins.

Remember your Cummins Power Club card- or sign up for 1 when you go in. Gets 10% off your bill- pays for itself in 1 trip to Cummins. Want to guess how I know?........................

Water entering combustion spaces will create white smoke. Faulty head gaskets and cracked cylinder heads or blocks are a common cause of water entry, and are often to blame. Unfortunately, expensive mechanical repair if this is the cause.

Not going to write off your Cummins just yet. Check fuel pressure. Filters can be clear and lift pump the problem. Can cause starvation and then possibly white smoke. Keep fingers crossed too.

White smoke from coolant in the combustion chamber usually dissipates/evaporates not too far from the exhaust. White smoke from fuel lingers for a while.

Most radiator shops can quickly check for products of combustion in the coolant. Coolant level would also be down.

When I had a problem with the red STOP engine light, it turned out to be algae in the fuel. New fuel filters solved my problem.

It would help if more info was mentioned such as running smooth or rough, loss of power or not, and loss of coolant ?
Cummins recommends having their shop check it out.
Cummins does not list any 707 code for the ISM that I can find, few close have to do with my original post.

I had The Yellow light come on one's and all it was , low coolant level. If the coolant level is below the sensor that is on the bottom of your overflow tank it will come on. Just fill and the problem is solved.

I had bought a 45KW diesel generator that had been on a Verizon cell site. Generator after 10 years only had 400 hrs on it. When I got it home and started it, it blew out all kinds of white smoke. Turned out the engine was not getting enough fuel since the tank had jelled up. Once had new filters, cleaned out fuel lines and with good fuel the generator has run great since.

Curious minds want to know: What do you do with a 45 kW generator? It definitely would fit in the "whole house" category! What sort of fuel consumption does it have?

Yes a 45 kW Is about average for a medium home, our range is from 20 thru 300 for homes.
For commercial, We handle up thru 3.2 mw. 99% Cummins, rest are Kohler & Cat.
I always get a chuckle when homes are over 30,000 sq ft, seems to be a new fad going around along with costs getting over $20M.

Guys,

Let's get the discussion back on the OP's issue-- Troubleshooting Red Check Engine Light.....

You know you could do an old school check. Stick your hand in front of the exhaust then smell what is on your hand. Does it become wet with fuel or coolant? Coolant should smell sweet... ish.. The fleetguard OAT coolant I use doesn't smell as sweet as the normal green coolant. If it's coolant... it's pretty universally bad. Fuel not necessarily as bad. Plenty of other fine suggestions as well.

I hope the fix for this problem is simple and inexpensive. The time to troubleshoot is as soon as a light comes on.
What was the engine temperature when the light(s) went on and how far was the coach driven after that point?

Re: Troubleshooting Red Check Engine Light and White Smoke

Reply #18 – December 20, 2015, 01:43:57 pm

Could you follow up if you find out what went wrong with this engine? It is the same as mine and the info would be helpful

Re: Troubleshooting Red Check Engine Light and White Smoke

Reply #19 – December 20, 2015, 06:28:02 pm

Thanks for all of the suggestions. I don't have all the information since this is a friends's coach and he is a good distance away from me. He is going to explore this problem more after Christmas. He did get the coach back to his home, he was less than 3 miles from his house when he got the red check engine light. I will let the forum know when he figures out what is wrong with the coach.

My friend has finally gotten his 2000 U320 coach back from Cummins. It ended up being the ECM. That part was $1,800 and then Cummins charged a bunch for labor because they went through the whole system to find the problem. Total bill was around $4,300. Ouch. But his coach is running great now.

Sure makes me like our 27 yr old coach--the one without all the fancy electronics!! Wow, the cost of a complete set of new Michelin tires plus a tank of fuel!!

Re: Troubleshooting Red Check Engine Light and White Smoke

Reply #22 – February 11, 2016, 03:56:42 pm

$2,500.00 labor figures 3- 8hr days to find and fix his problem if they charge 100.00 per hr...

Mark,

It sounds like you have a lot of experience.

As a relative newbie, I would like to learn from that experience. It is possible that someone has a different perception than you, but that does not necessarily invalidate your personal observations and advice.

Please continue to contribute and share.

Thank you,
