ECM Replacement 5.9 Cummins (3rd Gen/Common Rail)

In this video I bring you guys along as I replace the ECM on my truck

[@wheyez1]

Just watched your video, thanks for the info, I noticed quite a few no turn over questions in the comments. I had that problem once before and it turned out to be the key. There’s a crystal in the key that works as a anti-theft system. Fortunately I had spare keys made. Exchanged key and it started right up.

Thanks for the video

[@dereksimenac8844]

Easier to lay underneath but never seen an old 5.9 that clean

[@ChrisRocha1672]

Same here I felt she was pretty clean I still miss that truck

[@chrischi6031]

I also have a 2006 mega cab automatic transmission with only 143K. She died while driving down the Hiway. I’m not getting nothing but a click no crank at all. I’ve put new red top optima batteries, new alternator, FCA replaced, transmission neutral sensor replaced, I’ve installed a new ignition switch and replaced every fuse.. still nothing but a click. Pulling 4 codes p5209, P1755, p0513 and p0532. I’m leaning toward my ECM now. Thanks for the video

[@ChrisRocha1672]

You have an interesting series of codes to say the least. They may have been caused by weak batteries. The 513 I'd recomend changing the batteries in your key fob. Check all of your connections and make sure your starter is ok. I've never seen an ECM cause a no crank in my experience. Given what all you have replaced my next guess would be the starter. I've seen in some cases if the ac compressor locks up it will cause a bo crank no start. Take off the serpentine belt and see if there is a difference. Lastly check your fan clutch harness if that shorts out on something it can do odd things

[@chrischi6031]

Chris Rocha thank you I’ll definitely look into that also. I have the transmission throttle valve coming and also purchased cam shaft crank sensor for piece of mind as I’m going through her. I’ve also cleaned up both battery terminals. I’d find it unbelievable if this motor froze up with only 143K and not a drop of oil missing. I had a mechanic come look at her and he could only get 1/8th turn by hand with a 4’ bar 😔😩

[@ChrisRocha1672]

@@chrischi6031 those engines make fantastic compression but I would be worried. I'd see if you could jump the starter directly and see if it can spin the engine

[@chrischi6031]

Chris Rocha looks like I get the same movement from the fan on that click only like 1/8 to 1/2 inch. She didn’t make a bang boom and no smoke out the back when it died. I swear the engine reeved up like I lost the transmission and thought somehow I went into neutral at first before she finally shut all the way down at 70 on the hiway.

@@chrischi6031 what do you mean from the fan on?

[@lanewantstorip]

I put my new ecm on and now it’s flashing security light and cranks but no start Checked all the wiring harness hots and grounds and everything check out well but still no start

[@ChrisRocha1672]

What year is your truck? I was wondering if I would have a security problem on mine and thankfully I didn't. It may just need a reprogram

[@FURFEELINGS_3]

Same throttle process with a 2009 6.7 Cummins same body style same location of ECM so I figure it’d be similar

[@moez462]

Is it similar? I’m having issue with the gas paddle codes.

[@omnphugs]

When the grid heater kicked on and the lights went dim did you fix it

[@ChrisRocha1672]

Only to a point

[@nickdarling9557]

Where you get new preprogrammed ECM FROM ?

[@TX-cumminsgriesel]

I keep getting p0868 and p0513 codes as well as a bunch of communication codes.. dodge dealership says it's the ecm because the trans all looks fine relating to the p0868 code and the p0513 they just needs new batteries is the fab. Every once in a while my trans goes into limp mode when the 0868 code comes up.. do you think it is in fact the ecm?? It's a 06 automatic. Good video with good angles and info 👍🏼👍🏼 Thnx chris

[@ChrisRocha1672]

Not having an automatic truck I honestly couldnt tell you. If its communication I'd look at the wiring first

[@jonnyborrego8474]

[@rickl7024]

Cummins,, junk ecm,,, enough said

[@fbilley3957]

I had help taking off the wiring harness so really why i dropped in was to get a good shot of the ground hook up. It would have been nice to see the whole side shot of the unit with all the wires in place. Otherwise i got some very useful info

[@ChrisRocha1672]

I understand that it was difficult for me to get a good angle on the ground wire. It was just attached to the bolt on the upper right though

[@ericjaquez4347]

Chris, can you provide any update on the new PCM?

[@ChrisRocha1672]

Never had any issues with it till the truck broke down almost a year later

[@ericjaquez4347]

@@ChrisRocha1672 did the truck beak down because of the PCM/ECM or was it something else?

[@ChrisRocha1672]

Something else. Long story short I lost a bolt to the injection pump. It vibrated and snapped the remaining bolts and I just couldn't afford the repaid

Hey I’m having an issue with my 07 6.7 Cummins. It flashes the electrical red light on the dash. And drops speed randomly. I tried putting a new gas pedal but it was same situation. Should I put a new ECM?

[@ChrisRocha1672]

You should be able to pull a trouble code if it's doing that. It'll point you in the right direction

[@avigoods719]

Sounds like a vgt problem. You should pull the code.

[@OutsideJustin]

I’m having the same issue now what was your fix?

[@moza-8660]

@@OutsideJustin we ordered ecm cuz all the codes pointed that way. But sold it within a month before the ecm ever got delivered. Dealer had some good deals on new 22’ Silverado 2500hd….

[@d3lyniceem808]

Mine is a 06 will not turn over. I’ve replaced the fuel pump, starter and batteries. A bad pcm will keep it from turning over right? I’d rather buy a new pcm than injectors

Hi just found this . I made the mistake of starting without doing the peddle reset that you show hear . I am not getting wot . Is there a way I can restart this process and do the pedal as you have shown here to get WOT

[@ChrisRocha1672]

To be honest I'm not sure. Maybe unplug the batteries for 30 minutes and try again

[@joshb.8883]

Did you figure out the wot problem

[@OGGventures_cruising]

Same thing here. Put a new one in and tried starting it. Truck ran for a few seconds then died. Did that 3 times and now it won't start at all. P code 2509. Tried un plugging battery for a while and tried again after lunch. This time doing what you showed. Is there a way to reset it or does it need to get a flash reset?😬

[@tristenoberlender9685]

Mine won’t start it will only crank with the theft light, should I send the ecm off to get the theft system bypassed

[@ChrisRocha1672]

Does the theft light come on or flash real fast during or just after cranking

Ok, so my speedometer doesn't work, ABS, Brakes, Check Engine lights stay on. Ran codes and they said speed sensor was bad. Changed still no speedometer and lights are still on. Ran codes again. Says ECM is bad. Do you think that the ECM is causing the Speedometer not to work and lights to stay on?

[@ChrisRocha1672]

It would depend on the exact code. In theory yes it can but that's usually the past point of failure

Its probably the ECM not being flashed. The BCM/SKIM doesnt recognize it thus it won't communicate and essentially it creates a no start

[@arthurhunnicutt7291]

I installed my refurbished ecm today. Left the battries disconnected, all went well. The reason I replaced the ecm was that I kept getting the lighting bolt throttle position sensor. I had it replaced by the dealership. 30 miles down the road, it tripped that code again. Took it back to the dealership, they kept it for several days then told me I needed a new computer. So put the new (refurbished) ecm in today, drove 10 miles and it started throwing that same code. I put in 2 New battries last week. I'm thinking it's something else and wasn't the computer after all. Would you have any suggestions? I'm beginning to think there's no answer for this.
