Super helpful video. Still trying to figure out what is the issue with my car The rear tailgate module doesn't communicate with any scanner Do you know what could cause it?
You should check the back right corner of your Bmw f25 sometimes water builds up and has no way to escape. The tailgate module should be around there. Check the inside for water damage.
@@Bmwdiagnostics92 the replacement one doesn't communicate. The original one was completely submerged in water. I bought another one and it still doesn't see it
@@voffchik26 you need to program/code the new module in to the car. It is recommanded to use Ista for this kind of work. But I think a non bmw software also can do the work.
@@Bmwdiagnostics92 I totally agree with you, however I was told that even if the module hasn't been coded or programmed as long as it's the same part number it should communicate ( at least being recognized by ISTA in the module tree) with the scanning software. In my case no software even see it. Says communication error with the module
@@voffchik26 did a bmw dealer tell you that? On newer BMWs you can't expect it to be that easy. If you replace a control unit. And the rep manuels in ista tell you to program/code the vehicle you need to do it. But if the prosess can't be completted. You should find a wiring diagram and check all power and grounds if that is okey you should try to read the communication lines with a osilloscope. I hope the water issue was taken care of before you replaced the module.
So, if I replace both struts, and replace the BCM, (all new parts) and still get nothing from the remoter or interior/exterior push buttons, and the errors are still: 801714, 801716, 801718, and 801720 "HVAC Hall sensor short circuit to positive" on both left and right sides..... WHAT is the solution?? I have Ista+ on my laptop, where would I go to "reprogram" or 'code" the module?? Help please???
Why did you replace the BCM? If you did replace the struts you need to go to service function and I think it is on Body try to find tailgate and see if you can relearn it. If you replace the BCM you need to program the vehicle with the Yellow ethernet cable and you need to put the Icom in to lan before you but it into the obd2 and then you need å charger that can deliver 13v and the ignition have to be on. Go to control unit replacement and work your way through there select BCM.
Thank you for sharing your knowledge and experience🙏🙏🙏
