DIY: Flash your LCM with Newer Software
281 - 300 of 316 Posts
I have done this, but ok.
You have done:
facelift sedan LCM on a touring. ✅ will work.
touring LCM on a facelift sedan. ❌ will not work
If you done a touring LCM (LL) on a facelift LCM (LH), then please share witch us. I did everything you said, I did everything in NCS...it not works.
I sold my touring LCM to another user who has it functioning in his sedan.
Why would there be a touring-specific LCM when for all intents and purposes they're identical cars?
No I tried it and it don't work for me.
The right taillight is not working, if they are switched on. If I use the Coming Home feature, they are working.
I flashed a blank .man, but changed nothing.
I changed some setting, like:
PIN37_49_PARKL or PIN29_30_PARK
Original: BMW 6 936 826 (ECE SA dyn LH m FLC)
Flashed: BMW 6 936 825 (ECE SA dyn LL m FLC)
Was it a pre facelift sedan?
This is a great tutorial, I was able to find a SW3.6 LCM and flash it and put it into my 2001 M3. I wrote the VIN and mileage with PA Soft since I don't have NCS Expert working. I also used PA Soft to disable bi-xennons.
OEM LED tails work, xenons work and level, no flickering or bulb out warnings.
Are there any issues I can run into since I didn't copy the VO over? My main concern is the PWM value for the LED tails (EF), but I think the donor LCM came from a car that would have had LED tails already.
I also have triple blink, fogs with high beams, and the euro hazard lights (although it's not a double blink, more like one quick blink then two quick blinks). Are these functions enabled because the donor LCM had them or does Terra's flash come with these enabled?

It is not fully correct. It worked like this with pre facelift LSZ (CI:26-CI:29) that all versions of one coding index had all same hardware and to change from halogen to xenon and vice versa it was OK just to change the front panel and recode the LSZ.
When LSZ2 (LSZ CI:31-CI:37) came after Y2K into production, there started the tendency to cut and save cost anywhere it is possible, so despite all LSZ2 was having the same "universal for all versions" PCB, they differed by the components soldered to the PCB.
The options that was possible to install/not install on the PCB included:
- driver for stepper motors controlling lights vertical aim adjustment
(missing in the AHL Xenon LSZ2 version for 2003/03+ Coupe and probably US LSZ2 versions)
- levelling sensors inputs conditioning parts [LSZ2 description contain "dyn"]
(missing in all but Xenon LSZ2 versions)
- LSZ2 pin 20 and pin 38 driver (the longest 28 pins chip on top of the PCB) [LSZ2 description contain "L" or "LL" when not installed and "H" or "LH" when installed]
(missing in all but Sedan or 2003/03+ Coupe LED rear tailights LSZ2 versions)
- front panel AHL ON indication LED driver
(missing in all but AHL LSZ2 version for 2003/03+ Coupe)
So, any AHL LSZ2 version will never control stepper motors directly in any of non-AHL E46 car despite properly coded, as there is no part to do it. There is AHL module that controls vertical and horizontal lights movement.
Any "LL" LSZ2 version will not control LSZ2 connector pins 20&38 (Sedan outer taillights or Coupe LED BFD lights despite properly coded, as there is no part to do it.
Any halogen or AHL LSZ2 version will not read any axle load levelling sensors despite properly coded, as there is no part to do it.
Any non-AHL LSZ2 version will not illuminate the AHL panel LED, when AHL panel attached to non-AHL LSZ2 version despite properly coded, as there is no part to do it. (I know it, I let desolder CPU pin grounding resistor off my PCB and let the driver, resistor and capacitor solder to PCB to allow it work on my non-AHL LSZ2.
When You are lucky and You find a LSZ2 with the most parts installed (ECE Xenon Sedan or 2003/03 Coupe version), You can use it in any other body version, but e.g. Touring or Compact LSZ2 version could not be used in Sedan properly.
The front panel with Automatic/Non-Automatic switch position can be exchanged with no issue. LSZ2 is ready for any front panel and when Automatic light contron position is chosen, it switches the lights ON when RLS is either missing or when present and it detects any lights ON conditions (dark, tunnel, rain, ...).

LSZ(2) pins to taillights assignement is here:
LSZ2 CI:35 for Xenon and Sedan with RLS - this is the very right LSZ2 to use.
I guess You did it, but if not, please check all those hints.
If none of this helps, I do not know what to do next...
I guess You did it, but if not, please check all those hints.
- Check and double check all the software and drivers version You installed. There should be the proper match between the system and the version of the SW (e.g. XP 32 bit version on WinXP 32bit computer).
- Check and double check the location and proper soldering of the pins on LSZ2 PCB You soldered the wires to, proper wires assignement for flash tool connector, propper connection of the connector to flash tool (not reversed if the connector is DIL flat ribbon and not individual wires)
- Check and double check jumper settings on the flash tools
- If it still does not work, try to get/borrow another computer, e.g. with Windows XP and try to install all SW there, when installed, test it again
- I always read the CPU first to test connection, if read successfuly, I save the result as well
If none of this helps, I do not know what to do next...
Stupid I choose a wrong programmer ( kinda blind😊).
Now flashing is okay.
So next to ncsexpert ...., I will hope I will manage this.
I am kinda noob at computer stuff😊

Just curious how do I read cpu, you mean at " interface menu" and choose detect usbdm interface?
You should do it with different program from the software pack, the USBDM Memory Dump.
Please see the original efc3 post with the USBDM LSZ2 guide at "Interest in updating LCMs to SW 4.0 or 4.5?", see post #51 of the thread.

Interest in updating LCMs to SW 4.0 or 4.5?
with NCS, set CYCL_TI_BLK -> dreimal workzz! thank you so much.. so aside from teh triple blink, anything i can enable on an 4.0LCM thats not in my old 3.6?
www.e46fanatics.com
So shoulc I follow post nr1 or post 51 to flash ?
See efc3 post #51 for NOTE in step 4 about EEPROM write in the other thread. It was valid for the SW version 4.12 in 2016 when efc3 wrote it, I had downloaded that version back then and I follow the original guide to the letter. The current version of the USBDM software might have definition for MC9S12DJ64 EEPROM programming already included (I did not test it), so You can try it to follow post #1 here and if You still detect CI:35 LSZ2 after flash, it means no EEPROM was programmed and then follow the efc3 write step 4 NOTE to flash EEPROM to LSZ2 CPU as well (EEPROM contains new partnumber and coding index 37 values when read with diagnostic).
How to change the VIN in LSZ2 to Your car's VIN, storing of Your car's proper FA into LSZ2 and coding of the LSZ2 according Your car's proper FA is written here in post #1. Do not forget follow it as well. Then You can customize Your LSZ2 setting as You wish.

Thank, than I will follow post nr1 with 4,7 software. Will see what happen, finger crossed with coding ncsxpert.
What do do mean by FA?
What do do mean by FA?
Just to note, as I reffered to software versions (v4.12), it was always the version of the USBDM software version.
Do not mix it with the LSZ2 firmware version. They are those:
Note, the LSZ2 coding index 37 has two version of firmware, v45 and v47. I cannot tell the difference in function (beside the 92 blocks that differ in S19 files), but I would recommend to use the last version v47. Let us assume, that the later version is a bugfix to the first release.
Do not mix it with the LSZ2 firmware version. They are those:
- SW 3.6 for LSZ2 coding index 35 (source LSZ2)
- SW 4.0 for LSZ2 coding index 36 (older CI, better move to the last one)
- SW 4.5 for LSZ2 coding index 37 (FW made 2006-10-16, s19 file in original thread post #51 - see my link in post #295 above)
- SW 4.7 for LSZ2 coding index 37 (FW made 2007-02-07, s19 file in this thread post #1)

Thank you, I will try the latest one.....
