By the end of reading through this BMW document...you should have a greater grasp of a lot of the electronic systems in your car...including EWS/DWA/FZV (immobilizing sytem/central locking system/anti-theft alarm siren system)...and the seat/mirrors/steering column operations etc.

You can see in the topology chart below...how the GM III is the main control module for multiple systems around your vehicle...and if you download the PDF (at the link above)...it will go into detail how all these systems communicate & interact with each other.

Hello. Sorry to hijack a thread but......Would this also control automatic headlights and hazard flashers? My 2002 X5 E53 is having the key remote lock/unlock issue, hazards coming on after unlocking car and automatic headlights going off while driving. Headlights set to ON stay on tho.

Thanks

I would recommend starting a NEW thread and then referencing this one.

You're issue spans multiple features that rely on several different modules.

I was wondering who would bring up a thread/post that is over 7 years old. Did you even try scanning the car?

Yes and this is all Torque showed.

Torque is just a Generic scanner. To scan all of the modules in a BMW you need a scanner that does BMW. I used Carsoft 6.5 when I had an E34 Touring and BMW Scanner 1.4 when I owned the X.

I have a Foxwell 14020SCH scanner and BMW Scanner 1.4 but I'm not that familiar with either one.
Does BMW Scanner have a way to save the errors it finds to a file?

No...the LCM/LCM III/LCM IV controls all external lighting & the hazard flashers.


Since you're experiencing odd electrical gremlins that appear to sometimes be unrelated...have you checked your ignition switch? The iggy switch issue is more common to the e38 & e39...but the e53 is a generational cousin so could befall the same malady.



If you have the vehicle running (lights on, radio on)...pull down the passenger sun visor and open the cover to the mirror. Take note if you can get odd electrical gremlins to replicate or appear when you do this. If it does happen...then the ignition switch is more than likely the problem since all of those things get powered when the ignition is on (terminal is in KL R, KL 15, or KL 30).

Wouldnt I have some sort of issues with the ignition itself? Like not engaging the starter or something?
