Does E70 4.8L Have this module?

[e70jane]

I think this is the reason why I cant clear the faults on the sunroof, backup battery discharge, energy saving mode active, and ac k-can failure from carly.

If not, which is the module that controls it? I'm guessing they are all controlled by the same module, no?

cant read the PN

Is there a module that controls a/c as well as the sunroof?

Ditto ard in regards to the module in your first post....it isn't legible...is it the JBE? If YOU can see the 11 digit BMW part number...you can type/paste that into the part number search box on one of the online part database sites to see which BMW models uses it (like www.realoem.com or BMWfans.info.

Looks like the AC's & sunroof's direct control modules (the "control center roof" & IHKA) are under the control of one of the major gateway modules...the JBE (junction box) module: https://www.newtis.info/tisv2/a/en/e...ronics/csgGD2D

Here's another link to info about the JBE: https://www.newtis.info/tisv2/a/en/e...ronics/XVDnMDM

The air conditioning/heating system's control module is the IHKA: https://www.newtis.info/tisv2/a/en/e...rsion/GP9io2f2.

The sunroof (based on the wiring diagram from the TIS website) is under the control of the "control center, roof" (that big thing right in the front center of your headliner:

Ok, I see. Thank you anyway. I guess Ill just have to locate all the modules and test all the lines with a oscilloscope. I know I've got a bad line somewhere that's causing all the CAN faults on my car.

Check the JBE (you replied before I was finished with my reply...I was still searching for info). Go back and re-read and check the links and info in post #4...it has been edited and additional info and links added since your follow-up reply.

Im confused...why?

Becuase you cannot figure out how to (1) post a larger picture or (2) find the part number yourself or (3) tell us where that module was plucked from?


hint: BMW parts are xx xx x xxx xxx...11 digits...but often, the leave off the first 4..so you only will find x.xxx.xxx

I believe the jbe is also known as the body control module. I’m willing to bet this is the culprit after all that’s been tested on my vehicle. Do you know if this module is interchangeable if it’s from the same yr make and model? I want to avoid bmw at all cost because they will surely overcharge for programming. My x5 is a 2007 4.8l fully loaded with dual climate controls. I also found a module from a 2008 4.8L, also fully loaded with dual climate controls too.

Any of the online part database sites will give you the other BMW models and production date/build date range that uses the same part. Just enter the last 7 digits of your VIN...then go to the ELECTRONICS diagrams and look for the JBE (junction box electronics). Click on the 11 digit BMW part nbr and it will list all the other BMW models that use the same part...also look at the supplemental info column for the build date range, too. The part database site will also give you other part nbrs that were superseded and let you know if they are retroactively exchangeable or not.



Example using a generic X5 4.8:

.. I've spent nearly a half year trying to fix the problem. 2yrs ago i bought the x5 from a small car lot because I was attracted to the price tag, 3rd roll, and mileage of just 49k. It drove fine for a few hundred miles until the cel appeared and accompanied by a slight hesitation. After minimal research I started off replacing the gas cap then even the 02's but it did nothing. The strange part was a reset of the computer the car would drive fine again with no cel but will return after around 50 miles of driving. I then used Carly to check for faults and a bunch came up, from pt can to kcan to vvti failure, anti theft system, ac, etc. The voltage was super low and sometimes resulted in a battery drain overnight so i bought a new battery and even registered it but no still difference. I then brought the truck to bmw to do the fuel pump and airbag recall and had them check the problem. They said the IBS neg cable was bad and replaced it and charged me over $500. I got back the vehicle and it drove fine because of the computer reset, but 20 miles later the problem came back. I took it back to bmw and complained a whole lot, so they kept the truck for a month to check everything for free, unusual but thankful! They narrowed down to the computer and found that the components and connectors were improperly secured in place and an aftermarket dme was installed. They said a new dme and programming were needed and "should" fix the problem. Of course it also came with a hefty price estimate so I took back the car. I wasn't convinced and shipped the dme to an independent shop specializing in bmw dme repairs, and paid the guys $450. Surprisingly, the unit was sent back with a refund of $400 because nothing was wrong it. How honest, right? They said there's no aftermarket dme's either and that the tamper seals on the unit only means it was repaired once before. So after all that, I'm back to square one. I then did more research and next I started to tackle the alternator. I spent $350 on a new valeo, what a waste of money. I replaced the cam shaft actuators, the eccentric sensors, vanos tested, no difference. I even went as far as replacing the throttle body harness, what a joke!



Anyhow, with the pandemic, I now have more time off and will try again to tackle the problem. This is why I revisited your post and started researching on the JBE. I came to realize that many bimmers with electrical issues were mostly a result of a faulty JBE. And due to the location of the unit and how most failures are a result of age and shock, I'm aware of a previous accident involving the passenger side fender, so I think this could likely be the case. If it does the trick, I will surely pay for a plane to ticket to Indiana and buy you many drinks, my friend. Thank you Q for sharing your knowledge and take care.
