Brake Controller

[BossHogg]

Are you guys going with aftermarket controllers mounting them in the standard kick panel location? I had a P3 in a previous truck but with long legs it was always getting bumped and just in the way.

Here is where I mounted my P2, I'm tall, 6' 4" and my knee/lower leg bumps the P2 on entry/exit. I don't like it here but couldn't find another location. Suggestions...(besides getting Chrysler to fix the issue).

Update: P3 installed, i just had to disconnect the one plug like boss hog said, have not hooked up to camper yet to try it, also Ram customer service called me back yesterday to ask if I made another appointment and offered a rental car for free if I need it, sounds like they are starting to listen to people a little, next appointment is monday.

Let's see, 50 plus page discussion here, every RAM and RAM Cummins forum I've been on has two or more threads running about the ITBM turning off the trailer brakes under 30 MPH, the icing, Tekonsha designs and builds an interface cable between their Prodigy brake controllers and RAM's factory ITBM connector. To add insult, webs sites are sell the P3/3024-P cable combination. You would think Ram would be beyond listening and taking action.

The ITBM issue discussed in this thread is limited to the 2015 model year (possibly the 2016s), for MY15 RAM redesigned the ITBM back to the traditional four wire and standard brake signal. The ITBM in my 2013 RAM works as expected.

I have a 2014 Ram, built Jan 14, and am experiencing the same problems you have been experiencing. I have to have the gain up to 10 to get any type of braking at all on my 5er. The problem seemed to get worse after a computer update,
After the last update all I get is static on the radio when tuned to an AM station. I do know that a computer update will reduce the fuel filter change % in the EVIC, It has happened to me 2 times.

I know.....Have to take the steps though like boss said. ill tell u what. Im glad the season is almost over. Now they have all winter to find a "fix". Im not buying another controller! Here are a couple links to pics of the 2 different ones. the one is for the 15 and the other is for 13-14 . Looks like the harnesses are the same? u can never go by what those clowns tell you. So if the harness from the 15 fits into the 14 itbm could the computer setup still be different? It has to be or they would have left the same part #, right?
If they give me some crap , ill show them the 7 volts and have them explain that. Better yet, take my truck out and smash into something and sue since all my visits are documented

Do not act too quick on a change out!
I have a 14 3500 Ram built Jan of 14 that has the same problems!
Did they start using the "15" controller in 14 at some point?

Hey guys check this link out. This guy had the same problem and got it fixed but it doesn't say what the issue was.
Brake Controller Not Working on RAM Pickup - Airstream Forums

Here is what he said the RV dealer did.

On the 2015 Ram the 7 pin receptacle that is joined to the bumper can be removed. That 7 pin receptacle then can be removed from the wiring harness via a quick release, sort of. After removing the the 7 pin they observed how the two plugs mated via looking at the marks on the electrical connections. One of them they felt did not look like a good connection. They used a dental tool and bent one of the leads. Then they filled all the connections with a clear electrical jelly stuff. After that we got the numbers. On full gain and full braking 10 volts plus is within spec. So I was told.

There have been a few people on here with the same problem but it was only a couple people.

My 2014 2500 has the same problem. I took it to the dealer and they supposedly tested it and said it worked fine. BS! They also had the nerve to tell me that some owners are installing after market controllers in their trucks that have the factory controller. No ****. Ram needs to address this problem or some of us need to get together and start a class action. After 8 recalls I am fed up with the crap from Ram.

Cant Dodge it so Ram it,

You may have other issues to deal with. What is the weight of your trailer? I see you actually did some measuring yourself, but was it done in actual driving conditions?

If you look through the entire thread it has already been shown that the 2014 ITBM works fine. Lokk at your part number and compare it to below. If it was a very late 2014 that you purchased it may have a 2015 ITBM.

nasaland, now you are starting to sound like FCA/Ram!
I also have a 2014 Ram (built Jan 14) and and am experiencing the same problem as the 15. It started after a software update.

Others have also posted that they have a 14 and are having the problem.

Well, I'm about to put the brake controller as well as the Ram to the test. Next Friday, we are heading out on probably at least a 12,000 mile trek through Canada and Alaska. Prior to the track bar mod that will be done next Monday, I've done about everything preventable that I can think of from all fluid changes, front drive shaft lube, and all new tires. As for the controller, I did find that the plug (box mount) to the receptacle had came loose. Second time. This time I removed and examined the socket and found not only the retainers broken but also that the harness to receptacle terminals are very weak and were not making a good connection. I tightened them and then used dielectric grease and finally sealed the connection with RTV. It was then that I noticed that I was set on light electric rather than heavy. After resetting I only pulled it around the drive which is very steep. In 4 Low, it would almost stop the units on the steep part of the hill. Think better than it ever has. After this trip I should know for sure any weak links with the Ram.

The behavior of the ITBM dropping output at speeds below 30 MPH is very much a software design. Get with your dealer or look at your service work order and see what modules they reflashed.

I am a big fan of if it isn't broke don't fix it. I tell my dealer do not reflash anything without my OK. They broke my 2013 with the Uconnect hack software update and after several months it still isn't right.

If you want to feel better about your RAM issues think about me, I have two of these monstrosities that dealers can't fix. I can't leave anything in my 2013 RAM, the doors randomly unlock themselves. Dealers say, "can't duplicate customer concern". I'm tired of hearing that. I asked to have my truck instrumented, a process where they hook up a CAN bus logger recording all of the vehicle's events. They won't do unless they can see the problem. What kind of logic is that.

Besides the ITBM screw-up on my 2015 RAM, the damn TPIS (tire pressure information system) standard on 3500 in place of TPMS, the TPIS screen was there one day and gone the next. Dealer reconfigures the vehicle, TPIS is back, for a while.

Between these two trucks and the technology screw-ups in RAM's software, I should have a permanently reserved loaner car at my dealer.

One day, this crap is going to push me over the edge. I'm glad I get free legal though my work. I feel better, thanks for listening.

Please read the later part of this thread, especially the area that talks about Continental and the patent. There were major changes made between model years. The majority of people who have had trouble with the 2014 ITBM have found it to be either plug wiring issues or trailer brake issues.

Please look at BossHoggs measurements. People on here who understand these changes and the theory of operation know how it should work, and have proven certain things that relate to the different model years.

Again, there are people here who are jumping in to the discussion without having the background info, or are trying to turn this thread into a 'what's the best aftermarket controller' thread.

...and believe me, in no way do I consider myself a proponent of Ram's take on this mess!

I mounted mine in the center console up by the dash where your keys are laying. Worked great and didn't have to lean over to use it.

2014 Ram ITBM

After spending over 4 hours reading every post to this thread and printing about 25 pages to take to the dealer service dept. Here is my situation.
I have a 2014 Ram built Jan 14 2014, I ordered the truck Dec 16 2013. When new the ITBM worked great, I still had to use a high gain around 8.5 to 9 with my fifth wheel RV. I have had several computer flash upgrades on the truck.

When hooking up to my 35 ft. fifth wheel I would always lift the landing gear about an inch and hold the slide to 100% and full gain then pull forward, this was to make sure the king pin was locked. When the truck was new and until recently the brakes on the trailer would hold the truck from going forward. The last time I did this I was able to drive off with no problem, the brakes did not hold. March of 2015 the brakes on the RV were serviced and adjusted I have towed the trailer 3 times since they were adjusted.

I feel that one of the recent computer flashes has changed the dynamic of the ITBM making it like the 2015 that is having problems. After a recent flash I used my 18 ft. car trailer, I could always lock up the brakes on it, I had no brakes at low speed and the indicator came on 2 times that the trailer had disconnected. I pulled over to check and everything was OK with the plug.

Today I was able to take the truck to a local utility trailer dealer, they work on my car trailer, to check the voltage at the plug. I know the signal is a PWM and you need a scope to actually see everything. The dealer has a test box that they use to check vehicle wiring, we were able to run the cable from the box into the cab of the truck.
Here is what we found:
ITBM set at Heavy Electric, Gain at 10, Slider at 100% (pulled all the way to left)
0 mph 7v 7A
20 mph 7v 7A
40 mph 11v 10A

At some point, I think it was a recent flash, my ITBM function has changed and started acting like the 2015 ITBM. I have a center console and I cannot see behind the dash to get the ITBM part number without removing a lot of the console.

Had no problems with my 04 Ram and after market brake controller!

Could you possibly post a picture? I'm having trouble visualizing the mounting and access to the manual brake control.

I do not have first hand knowledge of the ITBM in a 2014 RAM, just 2013 and 2015. The results you are showing are characteristic of the problem I see with MY15 ITBM. The actual speed number is 30 MPH on my 2015, above 30MPH I see 96% output or about 12.5 volts, ample to stop my trailer.

As far as PWM, it is not mistic by any means, it is simply another way to send power down a wire. PWM is a nifty way to allow a computer to modulate the amount of power thus the birth of proportional braking.

PWM is a square wave that runs between zero volts and battery voltage. The amount of time the square wave is on versus off controls the equivalent voltage and thus the amount of power. Don't let anyone tell you that you can not measure the voltage of a PWM signal, that isn't true. If your dealer delivers that line of horse sh$t, challenge them with this information and make them go to work for you. The cheap give-a-way DVMs Harbor Freight passes out will measure the equivalent voltage of a PWM signal.

Power through knowledge.

Ok here is my update my dealer or anyone else cant fix this problem there for i am installing a P3 with the proper adapter and leaving the factory itbc in place.
Chrysler customer care has asked me for my Proof of Purchase so that they can refund me the cost of the itbc we will see if that happens.As far as the location of the p3 TBD.

 

[delta ram]

P.S my dealer tried and worked very hard but could not come up with a fix they also stood up for me when it came to CCC.

 

[cc rider]

Yeah.....I wouldn't hold my breath. You're telling me they're going to refund $ without knowing what/if there is a problem? I know that we all know there is a problem. I would have took that person's name.

Yes i have his name and ccc id thanks for the help cc

Update: P3 installed, i just had to disconnect the one plug like boss hog said, have not hooked up to camper yet to try it, also Ram customer service called me back yesterday to ask if I made another appointment and offered a rental car for free if I need it, sounds like they are starting to listen to people a little, next appointment is monday.

UPDATE took truck to dealer as requested by Ram, the only problem is the woman from Ram CC thought the dealer was going to install after market controller and would of covered it, but I had already purchased it and installed it so they cant reimburse me due to not being installed by dealer and being under warranty, but then today she called back and told me she is looking into compensating me in a different way like a service contract or Gift card, I am extremely happy by the way that they are handling this. so ill keep you updated.

 

[cc rider]

Not to be a D!@# but , u were told u would be given a rental car and not be reimbursed for an aftermarket controller cause of the warranty. . But. U paid for a factory controller and a TRUCK that has a job to do and you're extremely happy?
They must love customers like you!

Well there was a misunderstanding as I didn't realize she thought the dealer ordered the controller and was going to install it on the next visit and I guess that's why she asked about a rental car, but since I bought and installed it they can't cover it so that's why she wants to compensate me in a different way, so let me know how you make out
