Hello,  I have followed this forum for years but just joined today. Because i've got a sad sad story. I hope you guys dont

get this code. Looking for some help maybe.

 

 

Reading over the forums from this site and cumminsforum,  i now fear my ecm has died. 

Truck running fine after 45 min freeway drive.  Get off freeway and truck starts to act funny.  Gauges going

ape ****(including temp gauge going full hot and then back to cold).  Pedal goes more and more 

unresponsive. (dead pedal). Rpm's are uncontrolled. Truck Rpm all over the place.  Truck lost its marbles. In limp mode with rms going full retard.(never go full retard)

limp it rest of the way home. Idle home in first gear up steep *** hill .  Thinking vp pump computer has died for sure.

 

But no it doesn't look like pump, My Codes from the reader.

0606-very bad code (ecm failure)

and a bunch of high input codes. that i'm guessing don't mean **** after the 0606.

,0113,0118,0123,0121,0238.

 

Testing truck

-truck will run for a few minutes. with no codes. When its warms up the rpm/gauge issues and codes come back.

-I have check alternator for ac noise. I have run truck with 140 alt fuse pulled.  Bought a new alternator that i will use later with new ecm. Just in case....

-I have checked apps sensor for fluctuation when truck rpm goes up on its own. Voltage does not move. (check with analog meter).

lt Blue with black tracer to ground.

-checked/cleaned a bunch of grounds including one by pass side battery.

 

Thinking about taking ecm off to polishing up the surface of engine and computer.?

Checking more for bad wiring, intermittent grounding someplace maybe....?

What do you guys think? Ecm Toast for sure? Could it be in the Pcm?

Where Can i find a good replacement or repair?  Nobody seems to sell new ones.

They all need to be programmed with right vin.  Some ebay sellers have them up for 800 bones. But idk

 

2002 5.9 5 speed.  Mods- raptor lift pump 1/2 inch lines. S@b Intake. Edge mileage max. gauges. 140k miles on truck

 

 

Mixed bag.

 

Like I know the WAIT TO START lag is bad memory. Lift pump on coming on is a MOSFET failed. Sensors with all hi or lo volts could be a ground or 5V supply (regulator) issue. The big problem is after opening the case can you fold it back up tight and get it sealed up without water getting in the case? 

What about a larger separate water tight case like those cases for fishing gear or radios? Just thinking out loud.

Wanted to ask.... is there any device can be placed on our rigs to protect against sudden alt failures and ac voltage spikes?

Or at least a gauge on the dash?

I cant find a gauge...  as for the filter, found this?

Good one CSM, .aircraft need the good stuff too. Thank you for looking around for that and wood be nice on the truck but, 349 bucks?. I'm still stuck in the 90's pricing for stuff.

 

Mopar Man should come up with something. He is electrical engineer and sell it on this forum. Mike did you hear that?

I've been looking for good quality diodes like what Nations Alternators sells. Hoping to find high quality replacements.

Maybe nations would sell something compatible?... Maybe they could cut us poor dodge guys a break here at the moparman site. 

 

Notice this site http://www.aspwholesale.com/ has parts for my old bosh unit, but i'm reluctant to rebuild it.

 

This looks like a nice alternator.  http://www.nationsstarteralternator.com/180-Amp-HP-High-Output-Alternator-for-2000-Dodge-p/13874-180-hp.htm?CartID=1

 

 

 

I run a 240 amp Mechman alternator. Pricey, but bulletproof

ok..so a problem with the new ecm after about 500 miles.  The cruise control does not work. It worked on my old ecm.   I think the one they sent is from a 99. I dont get anything, no instrument cruise "on light" , notta nutthin. 

 

On a 2002 5 speed mt the cruise is all controlled from the ecm?

I might just go without it since truck is running good otherwise. knock on wood. 

Cruise control isn't a ECM function. Cruise control is controlled by the PCM.

 

maybe a communication problem between pcm and ecm? possibly pcm and ecm on different software series.... could they have programmed new ecm wrong?

 

Also read on other posts that a smarty programmer could fix this with "recovery software".  Was thinking about getting a smarty.  thanks

The ECM has to have something to do with it. I had the same issue with my first ECM rebuild except my light stayed on all the time but the cruise did not work. This was actually the second from the same co. The first on did not work at all a generated a 606 code where the oe did not. When I replace the second with the Cummins reman the cruise worked. Never touched the PCM. It is still the oe,

I would be suspect of the rebuild. While everything but the cruise worked on mine it only lasted a year before leaving me stranded on the highway when it died. Just my personal opinion.

Yes it does.  I can confirm this.

 

I had ACR send another ecm out to fix the cruise control issue.  

The cruise control worked on this one but after about 2 blocks down the road the ecm went into limp mode and the truck died.   It would not restart after that. So dam the luck.

 

Pulled that one out and reinstalled the first one they sent.  Truck started and running fine.  But,  still no cruise.  The cruise light does not even come on.  They seem like a decent company so this is kinda upsetting to me. Now i'm not having much faith in the first one they sent.

 

The question is.....whats the dodge/ram dealers source for rebuilt ecm's.  Does cummins rebuild them directly and only sell them to specific dealers?

 

 

I have no idea who rebuilds them but there seems to be several that sell them but dont know what they are doing. Mine came from Cummins but who did the work, I dont know. Found this on Ebay http://www.ebay.com/itm/Dodge-Cummins-2500-3500-Remanufactured-ECM-3947912-/281664808615?fits=Year%3A2002|Make%3ADodge|Model%3ARam+2500&hash=item419487e6a7:g:snQAAOSwg3FUj1wh&vxp=mtr

and then on there website http://goecmdiesel.com/product19__cummins_isx_isb-ecm_isb.html. I have no experience with them. There is a member here that bought one and it did not solve his problem. He returned it. here is the thread
