Another ECM Toasted? 0606 death code

[Cumminsince1983]

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

Test your alternator. I bet your alternator is excessive high in AC noise. Also if you have any wiring mods to the grounds or noise filter makes sure to remove the filter and return all wiring back to stock configuration. 

 

 

[Me78569]

Did you pull the edge off and see if the issue goes away? 

 

also a short in a ground or sense wire on any of the engine sensors can cause VERY strange issues.  

 

I had an oil pressure sensor that internally shorted and caused this type of thing.

[Cumminsince1983]

Hey thanks for the reply, your no doubt the 2nd gen master.

 

Yeah thanks to reading around the forums here. checked the alternator for ac with a few meters(including a fluke). Ac seems to stay under .1 amp. I think it was maybe .05 a.   I thought maybe it was just a random spike. And maybe it is.....so ran truck with 140 alt fuse pulled. Rpm issues still there.

 

Took alt to napa to get it tested.  He couldn't find the right alt code or something for it to test the dang thing.  Its the 132a Bosch.

 

 

 

Thats a good idea, Ill try pulling the edge. IT's been on the truck for maybe 5 years though.Did you get the 0606 code with the shorted oil pressure sensor?

 

 

 

[leathermaneod]

You need to check for AC volts, not amps....definitely a good idea to check with different meters thought :-) Also just because your issues remain with the fuse pulled doesn't mean you don't have excessive noise, the damage could already have been done....Good thing you got a new alt for use with your new ecm, though you don't need it if yours tests ok. But its definitely a good thing to check periodically and when you put a new alt on.

[Cumminsince1983]

Oh yeah I meant .05 volts.  Good catch.  

 

Is it possible to get rid of the o606 after getting it. ? Or does that mean ecm is toast and I'm just checking these things to prevent another roasting

. I'm in denial about buying $500-900 part.

Does anyone just repair these boards? 

 

Thanks!

You describe what mine did when the ECM went. All the same symptoms and codes except for the 606. I only got that after installing a rebuilt one from an internet rebuilder. I would go thru the processes mentioned above just to be sure since the ECM is such a big ticket item.

[Mopar1973Man]

Alternator is the cause of the failure. The P0606 is the sign the ECM is damaged. 

[Cumminsince1983]

Put a new alternator on it and took the edge mileage max chip off. Same symptoms.  Although the rpms seem to really run away when applying a little pedal. I did replace the apps sensor last year from another dead pedal episode.  Maybe a failing apps is sign of alternator issues. 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. Maybe i should do a different test....

 

checked ac on the NEW alternator while engine was running.  .05 volts ac. alt to neg on battery.  Like you say the damage is most likely done already. Going to find someone who can test the old alternator better. I don't have a scope. probably will not put edge back on.  maybe a smarty tune or something.

 

codes

po606 Ecm

p0113 intake air tempcircuit high

po118 engine coolant temp circuit high

po123 app sensor high

po121 APPS Sensor Volts Do Not Agree Idle Validation Signal

 

Any recommendations on place to find Ecm? I am thinking allcomputerresources.com

 

[dripley]

All I can say is do some research and check them out good. I googled them came with a little good and a lot of bad. Alot of times folks are more apt to post there bad reviews while folks with success dont say any thing. So you still have to temper what you read.  

[Mopar1973Man]

ECM damage is already done... You are going to need to replace the ECM.

[dripley]

I am of the same opinion. You could borrow one and install it to verify if one is available to you. 

[Cumminsince1983]

 

-So just a little update on this.  The New Ecm from all computer resources is working like a charm...so far. 120 miles on it, knock on wood.

 

It did take them a week and a half to send it after payment. To get the "lifetime warranty"also had to send the old one back in.

 

 

-Back to the source of dead ecm on a 142k truck?

 

The old alternator was "Good" on oreillys machine. Napa guy could not get his machine to work. Way to go Napa guy.

Although the oreilly machine read .4 low and 2.5 high on the "ripple test"(these numbers may kill a dodge ecm?).  That was for the old bosch 132 amp unit. Doubting new nipondenso 136a unit is much better then the bosch. Have not tested new alt.

 

I agree with what others have said; The multi-meter test can help but it may not show what you need to see.  A nice oscilloscope( no one owns one) or a high quality computerized machine(not oreillys) is what you really need.

 

The test results are still inconclusive at this point....

 

 

 

-other ecm killer suspects

 

-Truck is running the raptor 150 lift pump. Its a big pump. Possibly causing strain on the batterys/electronic system. Possibly, but probably not the suspect

 

- pulled the edge mileage max off the truck to be safe. Im sure its fine.  Innocent until proved guilty... Anyone want to buy?.. 

 

-battery terminals were kinda dirty, but not too bad. 

 

-dodge stuck a bunch of  contemptible ecm's and vp44s (my vp44 died before 85k) on our trucks.  I think this is our killer. Hurry, someone arrest dodge for ecm/vp44 butchery...i mean ram...or fiat...or whatever the hell.

Most electronics are killed by high AC noise. 0.4 AC volts is a automatic fail... Normal good alternator is 0.01 to 0.03 AC volts. Marginal is 0.05 AC volts. Then a complete fail is 0.1 and above.

I've got a 10 year old AirDog 150 still never been an issue.

Also have ran a Edge Comp for over 10 year no issues even with a wire tap. ECM and VP44 still going.

Battery terminal can play a role in this problem. The lead contact between the cable and the battery post should be clean and bright. As for keeping it that way light coat the terminal with engine oil they will never corrode again. Grease is OK but uo all way get it on your clothes and your arm while working where oil will not.

I could tell a story of what happened but it would take to much time to type the entire thing. As for the electronics failure main problem is excessive AC noise. You above test was a FAIL and you cause to way things are frying out. Like My only lost in my truck was ABS computer so far. I've been through 4 alternators now.

Speaking as one who lost an ECM at 217k, going the rebuild route of the internet was a royal PITA. The unit in your picture looks to be professionally done. Mine looked like someone took a hammer and case to it. First one did not work and the second only lasted a year. I am surprised at the Cummins logo on it. Is Cummins giving them their blessing? $800 buck is very reasonable for a quality ECM. The rebuilt I received was anything but quality.

[Hawkez]

A lifetime warranty seems like a pretty good deal as long as they stay in business.  I wonder what that warranty covers or what would void that warranty?  This may be a silly question, but is the odometer stored in the ECM?

This may be hearsay.... Cummin's offered to sell them engine and electronics with a warranty.  They did not want to pay the $ for engine electronics.  So they voided the cummins warranty and mounted... other awesome hardware.  Hardware that works, but needs some tender lovin care to keep working.

 

Anyways. Recommendations on a good quality low noise alternator rebuild?  The new nippondenso 136a is probably not bosch quality.

Not sure but it does seem of good quality. website states  " Dealer Authorized! "MOPAR SPECIALIST" ."  

 

 

 

 

thanks for the help dudes.

So far on the stock side I've not seen anything worth while that's including either remanufactured or new. There are few members Nations Alternators and Mean Green but expect to pay much more for them.

[leathermaneod]

What is the source for this rebuilt ECM? It certainly looks very professionally done! Seems like something we should all stick in our back pocket for a rainy day. Maybe a sticky on the forum if nothing negative is found this source...

 All computer resources.   They have a website or you can find them on ebay.  They list the ecm's they have sold over a given time span.  Noticed Lots of dodge diesel owners have used them.  Not a good sign for dodge owners. 

 

Yes, i will update if the ecm fails too soon and my alternator/batterys/cables/ext still look good.

 

Just for shits and giggles we should find what is "typically" going bad with the ecm itself.  Its probably a $2 part and some good soldering skills.
