Well, I messed up..

[Silverwolf2691]

Short version: Didnt drive the truck for a bit, jumped the truck, got it started. Drove it for a bit, then parked it. checked to see it would fire again after shutting it off, thought the wait to start didnt show up. next morning, slow crank. attempted to jump the truck, didnt fire off. swapped batteries now i have no CCD bus and no wait to start. i also attempted to jump the truck with the Quad hooked up the second time.. 

 

Long version: Last weekend (I think) I tried jump starting my truck. Havent started it since like late October. Finally got around to trying to get it started. Unhooked the Quad, put one of those lithium jump packs on, got it fired up. Let it idle for a few minutes, then took it for a short drive. Got back home. Shut it down, then tried to restart the truck. Truck fired right up, but I didnt think I had seen the Wait to start light. Tried again and no Wait to start.  I did hook my Quad back up at this point so it wasnt loose. Had stuff to do that night so thats how i left it.

 

Next morning went to start it, and slow crank. didnt think twice and threw a jump pack on and attempted to start the truck. Didnt help much. still cranked slow. Had to get to work so i just swapped to my challenger and left it there.

 

Today, i swapped out my batteries. go to start the truck and no wait to start, no gauges, odometer is blinking, and i have 'no CCD' displayed on my overhead display and odometer.

 

Do I have a couple different problems or is there one common denominator? As soon as i post this im going to start digging into articles as well to see what I come up with. I'm already assuming due to the no wait to start light, that im going to have to send my ECU to auto computer specialist.

 

any input is appreciated.

[Silverwolf2691]

Been digging for a bit.

 

I'm Almost positive that one of the Control units is shot.. Possibly both.

 

From what i read the CCD system "lives" in the PCM. But the Wait to Start lives on the ECM. The CCD does talk to Both units but I dont know If a Failure in one Makes a failure of the other. (im thinking not.)

 

I guess the immedate questions i have are

Where do i start diagnosing this?

Can i run the engine with these issues? (if it starts)

Would the cluster codes help? if so how do i pull those? (i think this is the cluster test, Prob not helpful)

 

Just went out and double checked. im getting no info to the cluster. the gauges come off of rest but stay on the bottom of the ranges. i havent tried firing the truck off, i dont think it will from what i read..

 

I just dont Know where to start diagnosing down options. Or if im trying to avoid the truth.

Might be more along the lines of do i have to send one or both modules in to get fixed.

Pull codes using a code scanner.

[Silverwolf2691]

Cant connect with my OBDLink MX+. Will try with a different wired scanner tomorrow. 

 

Just straight up fails. Has power to the port but cant seem to communicate with my truck. 

 

No 'key trick' codes pulled either.

Double check the pins in the OBDII port I've had one pin push out and not make contact and cause this very issue. Pop the socket from the dash frame so you have a bit of slack. Then check each wire and you find one that pulls out really easy and the tab that locks has most likely bent just enough not to stay locked. 

[Silverwolf2691]

Sorry for the delay gents, between 2 weeks of rain and OT at work, been a bit nuts. I did a feel check on the OBD port but nothing feels out of place. Need to figure out how to remove it. Going out in a bit to do just that. 

 

My Dad and I did go through some fuses that sounded pertinent to the issues at hand and everything checked out. No Blown fuses. 

 

I dont know if this is an effect of the no CCD or Wait to Start not lighting up, but engine cranks with no start. Probably from CCD if i had to guess. That seems to control (talk to at a minimum) everything in the truck.

 

I'm headed out to to take a daylight look at things. See if anything is obvious.

 

Probably look at what needs to be done for a W-T Mod as well. I need battery cables and was going to get some of the military terminal ones from ceautoelectricsupply.com. See if i can get some of the Mod wires all set to be installed with the kit.

[Silverwolf2691]

Alright, just got back in from looking over the truck.

 

No pins move more than i would think is acceptable in the OBD port. They move a bit, like sub 1/16-1/32, but I think that was standard/acceptable for most electrical connectors.

 

I dont see any obvious wire breakage or actual rats nests.

 Have you checked all the ground wires? Make sure everything is grounding properly.

 You said you checked fuses, did you check in both fuse panels? There is one under the hood and the other on the driver's side of the dash.

This is where I got my cable from when I did my truck.

I also used military connections.  They are great. Word of caution, look closely at them. I bought a 10 pack to have extra. You have to pay attention to the battery post hole. Positive will be bigger than negative.  There were five of each in my bag. I marked them with a marker for quick identification.

[Silverwolf2691]

Not yet on the ground wires..

 

Havent had an issue with grounds yet. Have had no electrical issues up until I swapped batteries.

 

Any fuses relevant to the issues im having in the dash fuse panel?

[Silverwolf2691]

Trying to keep up on things...

 

Called @Auto Computer Specialist about the time of my last post, Didnt get far. Was no way to leave a voicemail or talk to someone. Then called on Monday or Tuesday and spoke with Demetrius (sp?) about the issues I've been having. He said that its the ECU so that's what I'm gonna send in.

 

Fingers crossed  

[Silverwolf2691]

ECU is down in Florida with @Auto Computer Specialist. Turn around time should be 5 work days from Wednesday. Fingers crossed.  

[Mopar1973Man]

Should get a email of what happen to the ECM so let us know.

[Silverwolf2691]

Got my email from @Auto Computer Specialist today.

 

Apparently my CPU had started to come loose.. among other things.. 

 

 

ECU should be back Thursday. Next is some battery cables.. mine are not great. Work on the W-T mod as well while getting this swapped..

Looks like your problem solved...👍

[Silverwolf2691]

I hope so.. kinda need my truck back to do some stuff around the house. And i dont have snow tires for the challenger yet.. but southern new england is in a snow drought right now so I'll take all the dry days i can get at the moment.

[JAG1]

You got my attention on this as I get a 'CCD' on my overhead about every 2-4 mos. and it goes away without any symptoms at all. Keep in mind that a bad starter can put a tremendous load on the entire electrical system. I once had 2 newer batteries draw down to nothing  with just one short try with the key to start.

[Silverwolf2691]

Ok final update.. 

Got the ecu back and put it in.. and same symptoms. Took a bit to get back to it so the truck sat for a while. Finally got back to it today and started looking at fuses again.

 

Sure enough fuse number 9 labeled 'engine' was blown. Replaced it had no ccd issues and my wait to start was back. So i am back to a running cummins.

[Mopar1973Man]

Yeah, you gotta look closely for cracked fuses. I've seen fuses that cracked and look like they are whole and not blown but still don't work. Blown fuses are a little easier to see.
