Pre-LCI to LCI Xenon AHL Conversion: Resetting and Coding ALC Modules
Adaptive Light Control modules, also known as Stepper Motor Controllers (SMC), are coded to
operate specifically for the vehicle and side they are installed in. Thus, installing used ALC
modules could result in directional aiming in the opposite direction of steering travel than is
expected. Recoding them into their new position first requires that they be reset; otherwise,
recoding them may have no effect.
The procedures described herein were conducted with NCS Expert Tool version 4.0.1 running
under Windows 7 x64. Vehicle was a 2008 335i Sport Sedan AT with FRM2 module standard,
firmware version FRM2_E89.C09. The LSMC and RSMC modules coded had firmware version
SMCDS_LI.CO7 and SMCDS_RE.CO7 respectively.
Resetting ALC (SMC) Modules
1. Launch NCS Expert Tool, and from the menu bar choose
File
->
Load Profile
menu…
…select the “Expertmode Profile” or “ExpertmodusExpertmodus (Werkseinstellung)”
(depending on what “expert” profiles you have available or installed), then click on
OK.
These “expert” profiles should
not
have the “FSW-/PSW-Manipulate with FSW_PSW.MAN”
option enabled; if necessary, edit the profile to disable this option to prevent errors from
occurring during the reset procedures (save the profile under a unique name).
2. Click on the
FG/ZCS/FA
button (or press [F1])…
…then the
ZCS/FA f. ECU
button ([F3]).
3. Select the “E89” chassis, click on
OK…
…select “CAS”, “FRM”, or “NFRM” ECU (it doesn’t matter which), then
OK.
This preloads the VIN into NCS Expert Tool so it won’t need to be manually entered for
follow-on operations. NCS Expert is now ready to process ECUs.
4. Click on the
Back
button ([F6])…
…then
Process ECU
button ([F3]).
