Just replaced my LCM and the turn signals arent working

[Groshbri]

So i just replaced the LCM in my 2000 bmw 540i because the last one needed replaced due to the front left and back right turning signals not working and now that i put the new one in the hazard lights working but the turn signals, high beam, lights dont work. I use the either turn signal not flashes or sound on cluster and they arent on out side either, same with lights and high beams. I had this happen before when my original LCM was in and i had a bad battery at the time and after i jump started the car one time it was fixed so i dont know if this is just my car or what. Also when i plug my old LCM in the turn signals and everything work fine besides the lights that didnt work before. if anyone can help its much appreciated.

Did you code it?

LCM is probably from an e38 or e53. It needs to be coded to your car for them to work right. You will also have a tamper light on your cluster and a mileage discrepancy between the LCM and cluster. If you need help with all this, PM me.

You haven't coded the LCM. NCS Expert is best for doing that.

Use an expert mode profile. You need to read the ZCS code in NCS Expert from the EWS, the process ECU and select LCM. Finally, run SG_codieren to set defaults for your car. Read the ncsdummy DIY if you need more details.

I have an E39 1998. I replaced the LCM 2 with LCM 4 and everything was hunky dory, but now a week later my turn signals don't indicate. They work but no green flashing or click. Also the headlight and high beam indicators don't work. The lights work fine but indicators don't.
I did code with NCS Expert and it sees it as LCM4 c22. I get errors in PASoft under shadow : 7C [124] and 7D [125] "Front turn signal indicator failure.

I do notice that NCSDummy doesn't seem to like LCM 4 C22 with E39.

Any help appreciated.

I disconnected the battery and now everything works . Brights, turn signal indicator work fine.
This was an LCM4 C22 from an X5. I ran PASoft and set the VIN and mileage and then NCSexpert in expert mode with no man file and that wrote a file for a clean E39 LCM, then read the new file, modified with NCS Dummy and viola I have what I want, including LED taillights, courtesy 3 blink flash, and double blink hazard lights. My fogs also work with high beams. All of my bulbs are LED and cold and hot monitoring are off.
