It is really needed in this cold weather…
One of the most informative and easy to follow explanations on the BMW electrical system. Thank you!
Good video! Been looking for this.. thanks from Huntington Beach California!
Thank you my friend 🤗 I’m glad this does some help. It’s my first video so let me know if something’s missing!
The bonus test light DIY was also pretty cool! You should make a seprate clip just for that, I think others would find it helpful!
Thank you José I’m glad you like it ☺️ This is my beginner video and I totally had no idea how to manage episodes 😆 Maybe this project is too big for the beginning! Anyway thank you for the comment, I’ll try to improve as much as Y can 🤗
This is the best content I saw on youtube , thank you so much
Thank you Korhan, my pleasure! Please come back often!
nice work
Thank you Clifftone! I'm happy that you like it. Come back often for more DIY works!
Super pofessional work! I'm subscribed. Thanks so much! I have many DIY projects for my E93 Convertible Couple...
Hi Rufel thank you! I’m happy you enjoyed this video. Please come back often for more DIY projects 🤗
Excellent explanation! Keep up with good informative stuff abot BMW. ;)
Thank you SD! You are welcome to come back often!
Actually I'm going to be very busy in the incoming months; I'm become a father, having two examinations and one license to take... wow, I think I have to pause making videos for a while... but you can still find me via email or CZcams!
I will make a short communication talking about this plan. See you soon!
Great video. Will follow it to retrofit F10 M LCI heated wheel. What wheels are installed on your car? Looks awesome
Hi Alexander thank you very much 🤗 I bought this one from some seller from Belarus via eBay. I believe this one was from E70 X5 although I cannot find the part number on it 🤷♂️
Well the feel is not as good as the original M3 wheel (genuine leather or nappa leather). But it is okay for me 🤗
Why are the terminals named like this? Is it legacy from some ignition lock terminal naming?
Hi Janne thank you for raising this question so I got a chance to learn about it 🤗
I found the Wiki page about the standard DIN 72552 for naming in automobile wiring so I think this is the answer 👍
en.wikipedia.org/wiki/DIN_72552
I believe BMW has its unique naming system based on DIN 72552 standard.
Do you lose MDrive with this (M Button)? I see there's a unique number for the MDM SLZ's, but they don't list one that includes a heated steering wheel.
Hi Aaron you are right! The heated steering wheel is not available for E9x M3s. However, on the other E9xs, the heating circuit does not go via the SZL steering column switch cluster, instead it goes via the spiral clock spring (or coil spring cartridge per realoem.com) to the steering wheel. So the clock spring with the 4-pin extension harness is the key part for the retrofit. Swapping the clock spring allows additional wiring for the heater, and the M Button (actually the multifunction switch cluster) circuit is still there.
For whom is curious about the SZL for MDM, please refer to my video about MDrive retrofit: czcams.com/video/hIKka5dYtp0/video.html
Is there a relay that cuts off power to the radio ?
Hello the radio on E90s is named N38 or N38a. It is on terminal 30g_f and the relay is named I01139. This relay cannot be seen on my version of fuse box.
Please search on Google Images "e90 fuse panel relay 30g_f" you will see another version of fuse box on E90s. I01139 is on the right middle on the fuse panel, the black rectangular one below the black square one.
Be noted that there are some other modules on this terminal!
I didn’t get the notification for this , thanks I appreciate it after I reconnected my battery my radio and cruise control and other stuff stop working . I hope this relay is the problem there is only one fuse getting no power and it’s to the radio any advice it’s been like 2 years lol
Hi Gatiyo yes the relay I01139 is responsible for the power supply of terminal 30g_f. Also note that the faults in electrical system can make 30g_f shut down. So please scan for the fault codes about electrical system. Perhaps after clearing other faults, terminal 30g_f can be recovered!
@@funcarsgoodpeople thanks for the reply I appreciate it , 30g_f is a soldered relay on my fuse box I’m not getting no power to radio fuse and other fuses that has to do with the radio. Does this mean I’ll have to replace the fuse box ? This will be helpful
Hi Gatiyo yes this is one possibility but before swapping the whole fusebox I would try to supply 12V power to those fuses to verify whether the downstream modules are still functional.
Looking at the fuse slot F41 (if not i’ll update to you), you will see a colored (maybe blue or magenta) socket underneath. That is the pin to the radio. I would try to supply this pin to check the radio.
Do you know which fuse slot is terminal 30g_f? I would like to install the dash cam with surveillance parking by using this slot and preventing battery drain off. Thank you
Hi Eric from the wiring diagram for my 2008 E90 (with new version of fusebox), there are only two fuses on 30g_f; F31 for radio or CCC, and F17 for the phones and navigation system. Please note that the fuse distribution may vary. You can send your VIN via e-mail to funcarsgoodpeople@gmail.com and I can send you the PDF of wiring diagram of your BMW.
I had considered the parking surveillance and it's indeed a good idea to prevent the battery from draining out. I know Mio offer some kind of power cable to cut off power of the dashcam when voltage is too low. I also see some people use another battery for parking surveillance but this is not ideal for small cars (occupying more spaces.)
Thanks for your help. I have sent the VIN number to you.
Got it! Please see the mail!
So the fuses on 30g_f are:
F31, F32: Trailer module
F61: CAS (car access system, locking/inlocking the car)
F74: Instrument cluster
F60: Junction box
F59: Navigation
F56: CCC (the headunit)
@@funcarsgoodpeople Thank you so much for your help! I am successful to connect the dash cam as I wanted.
Wow great news! Eric! I’m thinking of trying to turn terminal 30g_f with ISTA+ to test an empty fuse slot. I’ll let you know if that is possible or not. See you!
Hi Carl, you seem very knowledgable on car electronics. I'm on youtube trying to find out why my 2013 mini r56's usb and aux port isnt getting any power. It used to work and one day it stopped working. The cigarette lighter works no problem and all other electrionics but the usb and aux port that are side by side don't work. Thinking it's a fuse or 30g_f turned off or not sure what issue but maybe you might have an idea? Appreciate this video and the new knowledge you provided me.
Hello Brendon thank you for the message. I am relying on ISTA for all of the problems I get. I refer to the wiring diagram of your R56 Mini. The USB and AUX ports are connected to the ULF (universal hand-free) module. Then the module sends sound signal to the audio unit via MOST circuit (optical signal, see my video: czcams.com/video/RhKOkYNZ65M/video.html)
If your ULF is broken, the MOST circuit is open and the audio system is also down. No sound will come out (try turning on the radio!) You can check fuse F10 to see if the of ULF module is out. Since USB and AUX ports are out simultaneously, I am assuming it can be a bad ULF module.
If the ULF is functional, maybe the USB and AUX harnesses are loose or broken. That's the idea I have right now.
I recommend using a diagnostic tool to see the fault codes. That will lead us to the problem more precisely. Best luck!
@@funcarsgoodpeople Thanks for the reponse! Radio works and no other electronics aren't working just the aux and usb port that are next to each other. I got under the usb and aux port and made sure it was plugged in properly and they were. Not sure if the other end got loose or not I didn't trace it back but they are connected at the ports. Another piece of information I can provide is that I got these two error codes when looking in the secret service menu on the dash.
Error01 A559 h 200038357B01
Error02 9314 h 2027582F8C00
Not sure if this has any meaning at all. I wasn't able to find anything online that explains. Really strange. I just want to have my usb and aux to work lol
@@brendonguo2494 I see! I cannot find related info in ISTA about the codes mentioned above. We'll just leave it alone.
So let's just check the other end of the AUX-IN harnesses. The ULF module is under the driver's seat. The connector of the USB harness is the black one X17182 with 4 pins.
And for the AUX lines they are in the black connector X17397 with 54 pins. The pins are 4, 5, 22 and 23.
Please check if these two connectors are firmly plugged and if their lines are intact. Let me know the result!
@@funcarsgoodpeople Thanks for the additional insight. I will look into this more about the ULF module and such. Appreciate your videos!
How many boats is supposed to be going through the ECU on a 2008 535 XI
Hi Robert, from what I found from the pin assignment, I believe that the supply voltage is 12V or the battery voltage. The ECU is also getting information about battery health. Are you encountering some power problem?
I put a new motor in the car it's a new turbos and the ground wire up underneath the motor mount was broke and but it's fixed now but I think it popped and relay or short or something out but it will car won't crank everything clears the code clears for the service and change all all that's back in the green but it still won't crank up and I put starter relay in it new starter
Hi Robert,
The engine start is controlled by the CAS, car access system. The CAS will compare a code stored in the ECU (or DME) to allow engine start. I guess you also changed the ECU together with the new motor(engine)? In that case, some programming is required to pair the CAS and ECU.
You can send me email: funcarsgoodpeople@gmail.com I will send you the related document in ISTA if you need 🤗
"Key identification and start procedure
The following procedure takes place after inserting the vehicle key in the ignition lock:
- The transponder in the key is powered via the loop aerial and sends the key data to the CAS control unit.
- The CAS control unit checks the key data to ensure it is correct and only then sends an enable signal to the starter.
- The CAS control unit sends the variable code to DME/DDE. There, the variable code is checked against the saved variable code; if they match, the fuel injection is released.
- After the engine has started, the CAS control unit generates new key data (change code) and transfers them to the transponder in the key.
- A new variable code is also created and stored in the DME/DDE control unit."
Falha no terminal 15 como resolver BMW série 5 f10.
Olá Marcílio! Você pode nos mostrar os códigos de falha?
Grosso modo, o terminal 15 é acionado pelo módulo CAS (Car Access System). Portanto, pode haver algo errado com o CAS. Os códigos de falha informarão detalhadamente sobre o mau funcionamento.

Hello Marcilio! Can you show us the fault codes?
Roughly speaking, terminal 15 is activated by the CAS (Car Access System) module. So there may be something wrong with CAS. The fault codes will tell about the malfunction in detail.
Thank you. I got an error code for 2008 BMW 328i:
Can communication analysis/Most systems:
A0B2 supply, terminal 30e/30l
Where is terminal 30e/30l?
Hi Hong I did some search and I have the following suggestion:
A0B2 for 2008 BMW 328i LCI is the fault code regarding power supply of CAS. Terminal 30E means power supply from Terminal 30 to power electronics in CAS, where 30L is to power electric loads activated by CAS.
The CAS has two power inputs from fuse 36 (40 Amp) and fuse 55 (5 Amp) coming from terminal 30, namely 30L and 30E. So please check if these two fuses on the fuse box are blown.
Please come back and let us know the results!
@@funcarsgoodpeople Thank you very much for your reply. I checked the two fuses as suggested and found that they are good. A0B2 code no longer appeared after I erased the codes.
Other codes include:
CAS Car Access System:
1. A0B4 Engine start, starter operation
ECM Engine Control Module
1. 2DEB Power management vehicle electrical system
2. CDAD Message (request wheel torque, drive train,BF)
3. CD99 Message (torque request EGS, B5)
4. CDA1 Message (steering0wheel angle, C4)
5. CD9E Transmission data 2, 1A2
SC Dynamic Stability Control:
1. 5DF4 System voltage too low
JBE Junction-box Electronics
1. A6CF AUC sensor
INSTR Instrument Cluster
1. A559 Instrument cluster: Power supply has been switched off (closed-circuit current cutoff relay
F-SBX-H Interface box high
1. DE50 Ring break diagnosis has been carried out
F-SBX Interface box
1. D68D wake up network unsuccessful
Most system:
1. A0B4 Engine start, starter operation
CAN Communication Analysis
1. A0B4 Engine start, starter operation
I failed to start or jump started the car. No crank, no nothing. The battery drained super fast (from 12.5v- 9 v in half day).
Any suggestions would be highly appreciated.
Hi Hong, it appears that there is an electric power problem that makes these fault codes. To summarize the above codes, I'd say the ECM and DSC lost communication because they were not powered or the power was unstable.
So the priority is to have a running engine with stable electric power (with a good alternator.) But as you mentioned the battery drains very fast, let's suspect some short circuit somewhere on the car. I suggest first remove the fuses for unnecessary/unrelated modules for engine start (e.g. radio, air conditioning) to isolate CAS, ECM(or DME) and DSC.
And now the car cannot be jumpstarted, so I will first check the starter motor, fuel pump and ignition electronics(wiring). It sounds like the ECM(or DME) is not working properly. I'm glad you can still read the fault codes and we don't see something catastrophic at this moment.
Could you please send me your VIN via email: funcarsgoodpeople@gmail.com so I can check corresponding documents and wiring diagrams on ISTA? I will also send them to you to bust the faults. Best wishes!
@@funcarsgoodpeople Just shot you an email with VIN. Thank you so much, Caril. I really appreciate your super great patience and help.
My pleasure! I hope everyone can be a faultbuster!
where is terminal 15 located ?
Hi Ben, the source of terminal 15 is located in the fuse panel. An earlier version of fuse panel has a removable relay. But later versions only have built-in relay for terminal 15.
The CAS module validates the car key and sends activation signal to the fuse panel to turn on terminal 15 when the ignition switch is pressed.
And some of the fuses are on terminal 15. Please see my video about how to find them because the location may vary by car models.

Hi Robert have you successfully fixed the no start problem? Please let us know!
