Hi there, Excellent video. I have a 2017 Jeep Grand Cherokee, was getting electronic stability control on, couldnt engage low gear, all sorts of things. I got a new TCCM via Amazon, replaced it with a friend in 5 minutes and voila !!....all iss back to normal. everthing works, coudlnt be happier !, not a penny wasted in labor and who knows what they could have charged me for the part. Juat wanted to share my experience, no programming no nothing, just take out the old TCCM and placed a new one, and that was all I did. Regards and thanks
I can’t thank you enough. I had my Service 4WD and service electronic stable control light on with the clunking noise at the start. I took it to the dealership, and they said the lights were due to internal failure of the Transfer case and the only way to resolve this is to replace the transfer case, which will cost me $4980.53, including parts and labor. I searched TH-cam for the issue; your video was the first search result. I ordered the Transfer case module from Amazon for $128 and replaced it as you explained, and the issue was fixed. Thank you again for saving me $$$$.
Super helpful -- took me less than 5 minutes to change mine out. Auto shop quoted me $500 for the part + labor and this cost me $26 and 10 minutes. Huge help. Thank you!
@abrahamgonzalezdelgado1717 actually it didn't work. The two different replacement parts made it worse (074AA part number). It actually works better with my original "bad" part. Car runs fine, it only occasionally gives me the "Service 4wd" indicator. The odd part is I know exactly when and where it's going to trigger. There are a couple small hills near home that trigger it. I can literally point my finger when it's about to go off. Like clockwork. I don't know what to make of it.
I have a code for transfer case control module, lost communication with a service electronic stability control light just bought one will it fix this problem? Comes in today
Did you try resetting the fault codes? You could have a bad TCM. Aso make sure your steering angle is correct when you check through the dash. Turn steering wheel from left to right and watch that it changes. Also, check for any broken wires on your speed sensors at each wheel.( this is common on the rears, cables rubbing through). Also, If you have an OBD reader you can check the rotation speed of each wheel while you drive. If there is any deviation in speed at one of the sensors change it as it's not picking up the speed correctly and thinks your car is losing traction constantly. Hope that helps and gives you something to check. 👍
I have codes C1476 stored and C1438 active however car runs fine no slipping only thing is when the car is downshifting u can feel it and traction light won’t go away , sometimes it randomly goes away and car downshifts normally , but then once car is off and on it comes back on . Would this be the tccm? The transfer case was rebuilt before.
I have a 2017 that has the clocking/spinning noise at startup accompanied by the clunking in the rear which worsens when turning sharply. I believe you may have saved me lots of money and time if what I am seeing here on your video is correct, so Thank You for this video, Sir. I did want to inquire if there are any scenarios where this part would need to be programmed? I called the Dodge dealership, and they state that it has to be reprogrammed to fit my vehicle. What do you think, Sir?
Mines it a 2014. I never reprogrammed mine. It was plug and play mate. You should be good to go. I bought mine from the dealer. It wasn't that expensive around Au$250.
@gbcautoworks Sir, I honestly believe that you have posted one of the most useful videos ever concerning the WK2. I see so many people with this issue on the forums and they change fluids, change transfer cases, pay dealerships thousands of dollars for them to play the guessing game. I can attest that the transfer case control module eliminated the clunk, the clicking at start-up, as well as the warning lights and depreciated ride comfort. $300, plug and play just as you stated!!! You literally saved me from considering trading my Jeep in, so many thanks to you, Sir for being willing to share your knowledge and expertise.
Wow, that's amazing mate, glad to hear. Thanks very much for your positive feedback. It means a lot. The whole point of these videos is that if I can help one person, then I am happy 😊 Thanks again! 👍👍👍
Hello I’m having same issue but my vehicle drives up to 25 miles nd just goes in lump mode transmission quoted me 4800 should I try the sensor first I’m really stressed out on having to spend 4800 not to mention I just purchased it from a dealer as well about 5 months ago it’s 2017 grand jeep Cherokee limited
I have a 2014 jeep grand cherokee laredo, what mine is doing is when is on idle or driving its making a clicking noise. Amd it just started about 3 weeks ago. It has 154,xxx miles i keep up with oil change when is due. What could this be i haven't taken it to a shop or anything yet, incase is an easy fix.
If the noise is coming from underneath the car, it's usually the TCM or your TCM motor. I would check for any damaged wires, then I would try resetting it through the obd port. If that doesn't work, try a TCM module.
2018 grand Cherokee limited started flashing 4WD low on the dash with a message saying “service electronic stability control” So I hooked up a code reader and it says “lost communication with transfer control module” Any ideas?
Hey mate, have you tried the easiest things first, battery power when the car is running , also any blown fuses, and checked for any broken wires around the wheels, at the module and at the transfer case motor. The cheapest option is the transfer case control module. Do you know anyone who could let you swap it out to see if it cures your issue?
@@gbcautoworks batteries are good, I am going to check the fuses tomorrow and replace them. As far as the transfer control module goes, I only unplugged it and plugged it back in. The broken wires for the wheels would be able to see from outside or underneath?
First of all, so glad to see your video, I may have a same problem on my 2015 grand Cherokee. I have been getting the service 4wd system for few days and then I realized I was getting the Electronic stability control indicator with the car icon. After checkin on a diagnostic computer, it shows error c1403-92. I wanna ask your expert advise if my issue would be the same as this that I need to change the device -as you showed?
What happens if you clear your codes? Does it come back straight away or after a few days? Error code indicates transfer case position sensor. Have you checked the connector plug and wiring at the sensor? Could be an issue there, the sensor itself or possibly at the module.
@@gbcautoworks thanks for getting back, yes unfortunately the error comes back. I have noticed a strange stiffness while turning Jeep extreme right or left, this happened twice. I will now check the connector plug as you have suggested. I have not taken the Jeep to dealer yet, as I am already in fear of huge quotation from them :(
@@gbcautoworks hi mate. Cleared all error codes but they come back, removed battery and then removed, cleaned sockets and plugged back the module from underneath the passenger seat. The error on 4WD service and 4wd shift in progress remains. I can drive the jeep but at full steering turns while parking the jeep feels jammed and doesn’t move easily. Shall I change the transfer case control module?
Your error code was for transfer case position sensor. It's either that, the module or your transfer case is faulty. Do you know anyone with another jeep who could swap out the module first to try prior to buying parts? Also, are all your TC and diff fluids clean and fresh? How many k's has it done?
@@gbcautoworks amazing idea, I will find out if I can locate another similar Jeep. Fluids all good and recently changed including transmission oil. Roughly 115,000 km. What is and TC diff fluid mate?
I have my 2015 Jeep Grand Cherokee Laredo, the traction light comes on when I'm on the highway and it won't let me increase speed, it stays in one gear, I have to turn it off and on for it to work normally again, do you think this is the error? and where can I get it programmed?
Sounds like the TCM module is faulty. Can you check the wiring connections to make sure that its all plugged in correctly? Have a look at Fuse F94. Do you have any friends with a similar Jeep that could let you swap over the module to check? Good luck. Hope you get it sorted 👍
Hello! How are you? I have a 2014 Jeep Grand Cherokee and the error P1D8C-00-PARK PAWL SOLENOID CIRCUIT OPEN. Mechanics were unable to clear the code and I think it must be a bad TCM. Will replacing it fix this?
Can you test the park paul solenoid to see if it's open circuit? An auto electrician should be able to help you out. There's no point changing the TCM if the solenoids open circuit. ( no electrical coil to activate the solenoid).
@@gbcautoworks I see, I think I'll try it with an automotive electrician. I hope it's not something worse and too expensive. Thank you very much for your help.
@@gbcautoworks that's interesting you list that part number. The part number my dealer gave was 68395074AA. However, I ordered 74AA and it didn't fix the problem. Wondering if I need to try 733AE
@@gbcautoworks FYI I've had none of the "noise" issues or driving issues with my 2015 Jeep GC. It drives absolutely perfect. However the "service 4WD" indicator comes on. I took it to the shop for diagnostic and it pulled codes for worn transfer case clutch. Tried this solution with the part I mentioned and no luck today.
The car was a bit clunky. I replaced the module, serviced the diffs and the transfer case. Reset adaptives and it's a lot better. I will Put some videos up soon.
@@gbcautoworksdoes that mean the jeep was jerking on acceleration? My 2015 is jerking and the dealer said the transfer case binding internally and advised to replace it. But I found your video and wondered if I should try this 1st. This video was very informative by the way. Thank you.
Are your rear wheels binding when you turn a sharp corner while parking etc? So if you put your steering wheel to left or right and try turning slowly you will hear the rear wheel dragging. Mine was doing this and I changed the rear diff fluid and transfer case fluid. It's worth a try before buying a new transfer case. I changed my transfer case module as I was getting a bit of a clunk now and again. Also, the transfer case motor can start to rattle on and off. This module change usually sorts out out.
I had issues with my jeep, dealership quoted it for 1k for the transfer case control module and said it was on backorder… just ordered the part and changed it myself.. now my service 4wd light is on with the traction control light.. any ideas?
@@gbcautoworks im pretty sure! Original issue was 4wd overheated unavailable light, wouldn’t shift into any other gears, and turning left or right when driving or reversing it would feel stuck… after changing the part it drives better just those two lights are on and it wont shift into any gears still Jeep service center said it would be the transfer case module
I would unplug the actuator first. See if it makes a difference. If not ,pull out the actuator and drive it a short distance and see if that helps with how it drives. I think it sounds like it's seizing up, hence why you have an overheating fault coming up. Also, pull out some of the diff fluid and check that too, make sure it's not all burnt and black in colour, which would indicate it needs changing. Did Jeep not do a thorough diagnosis of your car? Seems strange they said that it was the TCCM when clearly it's something else... Can you plug your car in and scan it. Then try resetting everything, including all adaptives. AlfaOBD is a good scan tool. Get the app on your phone and buy the obd port connection and your in. Hope that helps 🙏
Could be transfer case position sensor. Does the transfer case motor click or does the wheels bind when turning corners when parking up? Do you know anyone that you could swap the module with to rule it out?
@@gbcautoworks mine binds when cutting corners or back up into a parking spot. Had transfer case rebuilt and still doing it. No dash lights anymore though. What’s your suggestion?
@joselomeli3295 that's strange if it's still binding. Was it done by a reputable shop? Was the TC motor replaced too? Have you tried taking out the motor to see if the binding goes away ? Were all fluids done? I usually always do fluids on front and rear diffs as well as the TC after a service.
