As simple as it may sound, you will realize when you try to remove the PCM/ECU from the diesel Gladiator, that you will find the 4 nuts holding the PCM is near impossible to undo due to the limited access. Have searched online and there is no write up but scattered information about people...

Glad that you got it to work!

Any sales event coming up for the Black Friday 2025?

As I continued search for my answer I found the issue. Seems like there is a cable tie buried well below. Here is an awesome video showing what needs to be undone.

After playing with the idea of the leaving PCM on top of the fuse box lid, I realize there things get pretty hot and likely need a good air flow. I just got my 2nd and last free oil change from Jeep and I don't see myself taking the Jeep in for any repair in the foreseeable future. So decided...

I guess what you can try is vampire tap into the harness and apply current/voltage to the pump manually and have a physical switch to control that. Only thing I would be concerned is how this feedbacks into the BCM? Install diode maybe?

Took some time to have the ECU tuned. Sending it to Canada was quite a hassle. Used USPS to send it. Tow tune with DEF option. Had to clean fault code and power cycle a few times to get the engine light off. Haven't driven much but hope this helps engine to stay healthy.

My girl just turned 1 YO. Congrats on your newborn! ACC is pretty good. Absolutely worth every penny.

There you go. Can't believe this was over a year ago. https://www.jeepgladiatorforum.com/forum/threads/adaptive-cruise-control-acc-with-stop-post-factory-installation.85023/

Good to know. Thank you. What year range Ram translates to Gladiator Gen3?

It would be nice if you would share the cable cover. Any chance you would share it with the rest of the forum?

So 2020 Ram ECU works on a Gladiator?

I have ordered mine a few days ago and it is enroute. I will be putting on some tint before installing it on the truck for this reason.

Free if you have a USB drive! Check the first page on how to do this on your driveway.

Happy to hear this update is working and helping!!

I also have an FJ. That is a clearance light. Hardly enough to throw any light on the ground. Also requires you to remove the mirror to replace the bulb. Some people wire in different light fixture in there to make it brighter.

Most importantly, are you guys seeing improvements on the Uconnect?

@Synctheship which tune are you considering? DEF?

Thank you for checking the blank PCM and the verification error. I used 12V adapter that is supposedly better from Amazon but interestingly I had to power cycle when reading from the original PCM. I would definitely try higher amp rated adapter if I were to do this again.. My plan is to...

@dgeist Which tune did you go with by whom? I am curious to which tune y'all went with.
