Blind Spot Monitoring issue

[eer2001]

Ok so I have 400 miles on my 392 and the passenger mirror triangle for the Blind Spot is on and I am getting the message that Blind Spot Alert Unavailable. The brake light is clean and just for shits and giggles I cleaned the bumper sensors even though they are not part of the system from what I have read. I have not removed any doors either to mess up the door pins as this was something I read on another forum. Also, I checked the fuse and it is ok.

I went ahead and thought it might be the sensor/module in the passenger taillight, so I ordered a new sensor/module and installed it. Still not working.

I assume it is only the passenger one and did not try the drivers side swap since that light is not on.

Anyone have any suggestions?

Pins may be bent in connection. Had JT with same issue, bought new, doors never off. It’s covered under warranty. I figured it occurred at factory during assembly.

Thanks I’ll take a look at them! Just odd it worked fine for 400 miles then now it’s not with no changes. That’s why I thought the module.

Mine threw the message when I put on Rear Window Defroster, was driver side connection.

I believe they just put the pins straight; unsure if the module male/female was replaced. I never bothered to look at the invoice they gave me, just was happy the problem was resolved. I’m in the if it’s under warranty, it’s Jeep’s problem mode.
If they give you a hassle, just mention you’ll be calling the 800 number for Jeep. Somehow that statement changes the dealership’s attitude that I go to.

Yeah agree, I jsut don't want to go to the dealership and let them have it for X amount of time, teaaring thoguh stuff if it an easy fix or say $100 part (hence hwy I bought the module and took 10 mins to swap out). I will look at the pins again, thanks!!!

I had to take a good clean to those rear sensors like you mentioned … took more than once to clear this one for me.

Ok, so I have an update but no fix yet. AFter messing with fuses, changing the blond spot sensors, etc I was still getting errors. The past few weeks I was drivining without any cable/phone plugged into either of the USB ports and while it took a day or two the Blind Spot Sensors have been working flawlessly for the last week. My radio/uconnect is up to date so I am not sure how to fix the problem.
Any thoughts other than dealer as I will bring it up to the dealer when I head in for my first oil change?

The actual sensor lives in your tail light. Assuming it's clean, I'd pull the sensor and double check the connection. YouTube it and check it out.

Another issue could show up when you take off your/swap doors. The wiring harness has little 'pins' that can get bent when you disconnect/reconnect the harness.

Yeah I actually replaced my sensors on both taillights. Doors have not been removed either.

The issue seems to be when something is plugged into either USB port. If nothing is plugged in then the blind spot works fine. It’s very weird for sure.

I changed to the Oracle flush-mounts and neither side works very well. Are your taillights still stock? If so, pull the door harness and double check the pins. After that, Ive maxxed out my usefulness and it sounds like an issue for the dealer.

Scroll down to post #6 on this thread. It shows the layout of the system and all of the parts involved. There’s a lot more involved than just your tail light sensors. It could be an issue with your BCM (body control module):

I’m considering the Oracle Flush-mount Taillights. You mention here blind spot doesn’t work very well with them. Curious how much of an issue this is, can you please share how much of an issue you’ve experienced? Anyone else done this swap and having issues with blind spot on the Oracle lights?

Godspeed Youtube guy installed Oracle Flush mount taillights and had same issue...blind spot monitors would no longer work.

I changed out my tail lights
I had the oracle rounds in a for a second but the blind spot sensor is actually in the housing and needs to be moved
As I recall there wasn’t a spot to do this with the oracles and I went with the smoked JLs maybe from extreme terrain and when I installed needed to move the sensors over as well

I just installed the Oracle Lighting Flush Mount and can not get the Blind Spot Alert to work.
Message: Blind Spot Alert Unavailable Service Required
I did transfer the sensors from the old to the new tail lights.
If anyone gets them to work let us know!!

 

[prodriquez]

Did you test your wiring? It sounds like a loose connection.

This is interesting, I don't think I have seen my triangles light up yet. I get the back up sensor alarm but haven't seen the blind spot work yet. One would think on the interstate I would see that come on.

Yup, the do not work well in the Oracle flush mounts. It’s the price of looking cool
