I was having issues with my headlights and wiper fluid. Thought it was my FEM...but I also had issue with oil light coming on for no reason and my airbag light would sometimes stay on. Changed the front end module and still had head light issues. Then I read about hard reset of TIPM....so i did it. And low and behold my lights work, wipers work and the oil and air bag lights don't come on needlessly. Would suggest if you have weird electrical issue try the hard reset. I left it over night to make sure the solenoid was completely drained. Good luck!!

 

I know this is an older thread, but I am at my wits end with my TIPM. I'm hoping someone here can help because it seems that I am just throwing money away. Here is the story and current situation.

I have a 2008 Ram 2500 4x4, 6.7 with 6 speed manual, electric shift transfer case.

A few months ago, my truck wouldn't shift to 4x4, high or low. I kept fooling with it and it finally shifted, but when it did, the truck shut down. Truck started back up and was in 4hi, but wouldn't return to 2wd. I kept messing with it and it went to 4lo and truck died again. After it shifted to 4lo, it was stuck in 4lo. I ended up removing the T-Case motor and manually shifting it back to 2wd. I replaced the T-Case motor, but it wouldn't shift and I had the service 4x4 light on and while driving it, the 4hi & 4lo lights on the dash would flash randomly. So I changed the TIPM with a reman from Cardone. I still had random 4hi & 4lo lights flashing along with service 4x4, then the nuetral light on shift **** would come on randomly. I then changed the shift ****. After this the truck seemed fixed for a day or so. Then while driving down the road, it shifted into 4lo on its own. I was lucky enough to clutch it and pull over without exploding the T-Case. I shut the truck off for a few minutes and when I started it back up, it shifted back to 2wd. Later that day, the 4lo light started flashing, so I pulled over and it shifted to 4lo on its own again. This time it wouldn't shift back to 2wd, so I pulled the T-Case motor and shifted it manually. Currently, I have the motor unplugged. The service 4x4 light is on, which I understand why. The weird thing now is, when I turn my headlights on, the 4hi light flashes and it I cycle the headlight switch, the 4hi light stays on.

My question is..... could the Reman TIPM I bought be faulty? Could the T-Case motor be faulty? Should I try changing the TIPM with a brand new Mopar one along with a brand new T-Case motor and change them at the same time?

The Reman Cardone TIPM said that it didn't need to be flashed by the dealer. Would taking it to the dealer and having them flash it fix my issues? And if I bought a Brand New Mopar TIPM need to be flashed by the dealer?

Thanks for any incite on this issue, Im at my wits end.

 

 

I dug around on All Data yesterday, I found the test for the codes that its throwing, which is C140D & C1405. I did the test for C140D, which turned out to be the Tcase motor bad, which I guess you can get bad parts everyday. I didnt have time to do the test for the C1405 code, which it will tell me if the TIPM is bad. I'm wondering if the TIPM is putting more than 5.5 volts to the tcase motor and burning it up.

 

Seems like Dodge was sued for their lack of acknowledging this PROBLEM!

https://www.gotaclassaction.com/chry...tain-vehicles/
Plaintiffs bring this action on behalf of a proposed nationwide class of consumers who purchased or leased Chrysler vehicles equipped with the defective TIPM, or, in the alternative, on behalf of statewide classes of consumers who purchased or leased their Chrysler vehicles in California, Maryland, and Florida.

What Happened?

It will work if its the same part number and even Some are Interchangeable. Programming isn't necessary . Turn the key wait 30 seconds for before you start it after installing new tipm. That's all it takes for the car to recognize it and start communicating. technically the vin may be Incorrect in the tipm but won't effect anything that you will notice driving the car. Buy from reputable source do your reseach. I get all mine from flagshipone.com. make sure you diagnose dont buy one of these inless your 100% with proper diagnosis. Have a good day 🤙✌

 

I'm new on this forum . And late on this topic
To reset the Totally Integrated Power Module you need to disconnect
both battery cables and join them together for a few hours, this would drain
all the capacitor and do a "Hard Reset" .
I have tested that on my 2005 Dodge Magnum , trying to ad Bluetooth module for phone connection .
The TIPM gave a code saying there is a new controller on the CAN Bus
And I could not see the HFM (Hands Free Module) in my scanner
After doing this hard reset , the HFM came online , I could see it on my Solus scanner.
So likely if you find a TIPM that fits your vehicle generation , it should relearn all your components and option on your vehicle.
I will try a used one on my Magnum and be back with results. Just for fun .

 

Actually you can interchange the TIPM from different trucks so any early 3rd gen will work in any other early 3rd gen, i know because I have a 2003 ram 1500 5.7 hemi and a 2004 ram 2500 5.9 Cummins and I have tons of spare parts for the 1500 and the TIPM was bad in my 2004 5.9 diesel and so I tried the spare tipm i had that came from a 03 1500 5.7 and it works perfectly in my 5.9 Cummins with zero issues and no programing as long as the tipm your using comes from a truck with the same or more features then your truck then your fine. and YES diesel TIPM will interchange with a gas TIPM without any issue at all. heck the gas tipm has the fuse spots for the diesel, just read your tipm lid. and my odb-II works perfectly also so its false that they dont interchange in anyway and need programmed. even if you get one from a truck with less features than your truck you can take it and get the features unlocked. I have worked at the local dodge dealership for over 15 years, so I know my ram trucks inside and out. anytime mechanics tell you things need brought in and programmed they are usually trying to nail you for an expensive useless task because its easy and they can charge you a ton. so always do your research before paying a stealership $1,100 for a fuse box <3

 

Tipm died in neighbours 2010 wrangler. Searched and only one year made for that tipim. Que bababababulls$t. Just got back from the junk yard, spent 25$ on a tipm from a 2010 grand caravan. Guess what, FIXED and everything works perfectly no codes no drama FIXED!!! No programing nothing!

 

I just realized I never follow up with my FCM - TIPM story.
So on my ,05 Magnum , scanner would see the HFM present , but because it is not enable , it does not work.
So Using Alfa OBD or APPcar Diag FCA I simply enable the Hands Free Module . In the menu you select "Set" instead of "Not Set"
and of course a key cycle to reboot. After everything was working right.
So if you find a correct generation "TIPM" or "Gateway Module"(FCM) it should work , no need for vin writing
but if it came from a lesser equipped vehicle a few function will not work properly until "Set' or "Enable" with Alfa OBD
If it came from a fancier vehicle , a few codes might show up because of missing hardware from those extra options.
