All the bypass info I find is for the pre 2014 TIPM. I need help with my 2015. Is there a ready made bypass cable? A relay kit?

I don't want you to feel like you can't get any kind of attention here; so I will make a lame attempt.

Why are you wanting to bypass the pump relay? Is this a known-poor design that often fails? Or is this a "rock-crawler" that has to operate in odd attitudes, that the stock relay/system can't handle? I have no guess as to what that "TIPM" is.

Dear bill, TIPM mean "tottaly intregrated power module" fancy word from dodger.

 

[nickb2]

mostly meaning a bcm, ecm, tcm all in one, and when those go south, sell the dang vehicle. I am also going out on a limb, but from what my limited french brain understands, op is looking for a bypass to source out a fried relay in the TIPM. However, I would need to know which relay circuit he needs to bypass, so will wait on op to respond and see if he is serious enough to delve into this kind of project.

I thought I replied. Well I did, but apparently my reply didn't post. It is the fuel pump relay as stated in my subject line.

If you'd like to know: It's a common Chrysler problem. Recall covers some models. Not mine. No reason why not, it's the same problem as the recall. There are a plethora of bypass kits for the mini fuse TIPMs but not the micro fuse TIPMs. The bypass powers the FP via the cigarette lighter. I made a bypass and I'm running. I would like to fix it like the recall fix. The recall fix installs a Mopar external relay kit and the instructions provided give the wire colors so you don't have to trace everything down. That's what I wanted. I found one. I ordered one - charged my card and all. Then they refunded me and said it's a dealer item only. Investigation (friends in the business) said they have so many of them failing they are keeping the kit I ordered for themselves. I can order a standard relay sized appropriately but it would be nice to not have to reinvent the wheel as far as identifying the correct wires in the wiring schematic.

I don't know what happened to your reply. I can't find it being held up for any reason. Did you have a URL or similar link in it? That often triggers our spam filter.

I can understand not wanting to "reinvent the wheel", but since Mopar seems a bit poor on designing "wheels", maybe your DIY solution would be better. cheaper, and quicker...

Get the wiring diagram and I'll show you where to put your relay in. This relay is going to be PCM operated correct?

is this what you installed or ordered and did not get?

here is a wiring that may help.

 

[nickb2]

In this circuit, they call the tipm a PDC, same thing, just another way of dodge not respecting standardization. Wowser, I was able to actually write that word.

Yes grc, it is pcm operated. Pin 84 @ pdc grounds out and good to go. Many times, the transistor fries out, not the relay down south, up here, these pdc's go south cuz of green irish stuff known as corrosion due to road salt we put every where.
