I would test the battery and carefully check the battery connections and grounds. Could simply be a loose connection.

Someone gives you some things to check and you respond back with what if I replace the ECM. Well honestly, without you going through some basic troubleshooting you'll wind up just spending money hoping the problem will be fixed.

In addition, this really is something that could have been searched for on this forum as it's been asked many times before:
https://www.jkowners.com/forum/gtsea...0tree%20lights

I suggest instead of looking for a quick fix that you start listening to what people are telling you and perform some of the basic checks that have been suggested. I also suggest searching as well as most likely it's already been covered. If it comes down to all searching and suggestions don't work, then come back here posting what you've tried. This helps everyone to help you.

Good luck...

Could the problem be the ECM? Sure, I suppose.

Most likely? No.
Simplest? No.
Cheapest? No.
First thing I would check? No.

Have you done any testing that leads you to believe it is the ECM? With your symptoms Iíd say the TIPM is more likely than the ECM. Still not the first thing Iíd check though. Does it sometimes start and run properly?

I'd pay attention to the feedback above that folks took their time to give you at your request.

You've been provided good initial checks and a link to relevant threads.


So, you could:
Check battery + connections + grounds (the BASICS) -
- or -
Buy an ECM randomly and most likely unnecessarily -

Diagnosis takes some skill (unknown quantity) and a methodical approach (which you have not demonstrated).
Have you ever used a multimeter? If not, electronics are out of your league currently.
If you want to diagnose by just hanging parts, a bad repair shop can do that for you.

here's hoping the dose of truth or accurate advise didn't scare OP away.

I'd feel awkward coming into a bunch of strangers and announcing "I need help" ; if I did , I'd be listening to their recommendations & reply out of courtesy that I appreciate the pointers.

that's just me, tho'

Unplug the main connector at the front sway bar disconnect motor. shake out all the water and leave it unplugged and see if that fixes your issues.

I find your reply to my post a bit arrogant, I have been collecting data for at least 2 years, this has been a intermittent issue, all sensor lights and alarms going off but still running.
And an occasional no start, no starter power, and then it will start and run with intermittent sensor.
Yes I did check ground first.
I was nearly asking if anyone has had similar issues, I know Chrysler had a lot of issues with ecm,pcm,ecu and see what they did to correct the issue.

You should have stated that you checked grounds in your initial post. Instead you gave us half of the story.

No. You exactly asked if it is your ECM.
You do need help, I think we all agree on that.
Best course of action is to sell your jeep and get a bus pass, after you buy a new TIPM and ECM.
If you don't want answers don't ask questions you arrogant prick.

I find it funny you deleted your reply that stated you tried nothing and want advice on changing a part, so I find this reply not to be humble. Does this change the dynamics of what's going on? Hint: No

And you still want help, but still not giving the complete outline of what you've done and researched. What kind of reaction are you expecting when you don't give complete details? I expect you know already the reaction you already have received

Anyway, if you want more help then give compete details. It's really as simple as that.

No arogance intended. I simply gave my opinion, based on the extremely limited details given. I also asked for more details of the problem and asked what lead you to believe it is the computer. Not to discount your diagnoses, but to find out what troubleshooting had already been done.

Is your Jeep a Rubicon? If so, RPM Extremeís suggestion to unplug the sway bar disconnect is a good one. When water gets in and shorts the communication out it can really mess with things.

What data have you been collecting and what all have you checked? The more information, the better when troubleshooting anything. And itís even more important when troubleshooting over the internet since we canít look at the vehicle and only have the info you give.
