NEED HELP ASAP

[stinkfinger]

Guys, I am in a pinch here and need some help. The other day I went into limp mode and made it home, I got the service trans error message. I did some digging and noticed that fuse # F57 was Blown so naturally I replaced it and started it back up and it drove good for a few miles. so i parked it thinking everything was ok. Today my wife took the truck and the message came back. I am at work right now but I am sure the F57 fuse is proably burned out again. What could be cuasing this and what should I do or check to fix it?

could be anything your going to need to verify if that fuse is re blown and then scan the truck wih a good scantool most likely a wire issue if you are blowing fuses.

If that fuse is related to the transmission, I woul take a look at the harness/plug for the trans to see if any visible damage, or perhaps moisture/crud in that area.

It doesnt take a whole lot to potentially short out and cause issues.

Hoping for an eaay and simple fix for you.

You said you wife got the code, but did she verify it went back into limp?

You have to run the codes boss.

So fuse 57 has the TIPM under it?

Yes it does have the TIPM under it. Also yes, it did go back into limp mode. when i got home fuse 57 was blown again. i changed it for a second time and the truck started back up with no codes

TIPMs have a solder joints in them and they often corrode, and when they corrode they can fry the fuse just like a shorted wire would/could. Post the codes. Some items use the ground to communicate with PCM, so I doubt you can rewire but I don't know for sure. Most likely you need a new TIPM if it is fried.

That is what confuses me. I am not getting any check engine light, so there for no codes? or am i wrong on that one?

I have a parts truck that I bought. Could I swap TIPM's?

Just had a Convo with a RAM member so 2014 doesn't have locked PCM, so in theory it will work, you may need simple reset.

Where would I get that done? a dealership?

 

[Burla]

No look up hard reset, all you need is to have no power for 20 minutes at worse, recycles pcm.. And only if it needs it. Since you have to take off battery when doing it anyway, maybe it will reset itself.

Fuses typically only "blow" if there is a problem. The fuse itself just doesn't fail, but they blow because a wire is shorted out or there is some other problem. Just replacing the fuse rarely actually fixes the problem, and it will just blow again like you found out.
I wouldn't just start throwing parts at it without some testing. Sure, it could be the TIPM but just because you have a fuse blowing that is not the first thing I would do. You will need a wiring diagram and trace the wiring associated with the fuse location. It could just be a rubbed through wiring that is shorting out somewhere.

for sure!

Do you have any experience troubleshooting electronic circuits?
You will require a digital multimeter or a 12V test light at a minimum.
Harbour Freight and Walmart both sell inexpensive DMMs.

You can find a service manual at the link below.

Has anyone found a 4th generation service manual in a PDF format? If so can you please share the link? I can't get the McFall one to work on my phone. Thanks!

Please keep us updated on what caused the problem when/if you find out.

Before you start changing stuff, why not do a bit of work and check current draw on the circuit, pull the box out and look for green corrosion, check all plug ends as well.
then look close at all the wire harness for rubs, pinch wire, etc.
I would start at the lower end first. the plug, and any spot where the wire harness runs along the frame and such for bad insulation. it will be small if there is one as a bad short will blow fuse as soon as power is turned on.

Changing fuses will not fix anything, you have to find the reason.

You could hook a meter on current and watch the meter and go along and shake wires, wiggle connector's and see if you get a current spike.

Or take it to a shop and let them do it.

I most definitely will. So far I have swapped TIPM from a parts truck I bought and still blew the fuse so TIPM is not the problem. Pulled the main connector out of the transmission to check for corrosion or melted insulation. It look ok to me. I cut about 6” of wire wrap and heat wrap off at the end of that connection and noticed wires that were taped together. I thought maybe I found something, I don’t think that would’ve happened at the factory. So I took the tape off and was hoping to find melted insulation or exposed wire but it was damaged at all underneath the tape. I don’t know maybe that is the bad spot. I’m going to have to buy a multimeter and troubleshoot it that way. I know absolutely nothing about electrical so I rely on you guys to help me with that. Mechanically I’m good I just suck with circuits.
