Dsc problem

So I know if you hold the dsc button for like 5-10 sec you take stability control off as well as traction control but when I try doing it just the dsc light comes up but the brake light doesn't.

The turn DSC completely off and having the "BRAKE" light come on only applies to the later versions of DSC, cars produced after 09/2000 (2001 models and later) and not the M or Xi models.


See this document for more info: http://www.bmwtech.ru/pdf/e46/ST034/...20Internet.pdf
This info is posted here many times.


DSC III MK20
Model: E46 all versions except all-wheel drive
Production Dates: 6/99 to 9/00

DSC BUTTON
The DSC system comes on every time the vehicle is switched on. The DSC button can be
used to switch the system off. The warning indicator lamp comes on when the system is
manually switched off


************************************************************ *******

TEVES DSC III MK60
Model: E46 (except M3 and Xi) and E36/7
Production Date: From 9/00

DSC III MK60 is supplied by Continental Teves and supersedes the Teves DSC III MK20 EI
system. The MK60 includes all of the features of the previous MK20 EI system and incorporates
two additional functions:
DBC function
Modified ADB function

Modified ADB function (2-wheel drive vehicles equipped with MK60)
The ADB is an automatic differential lock that improves traction. The slipping wheel is
braked by pressure built up in the hydraulic unit. The drive torque can be transferred to the
wheel with the greater traction, which can transmit drive power to the road. This function
takes the place of a limited slip differential.

DSC Button
The DSC button is located on the SZM, however the SZM provides no processing, it is
simply a housing for the button which is hardwired to the MK60 control unit.
The DSC Button features two functions that can be set by varying the time the button is
held down for
:


Button activation Function Display

Short press: <2.5s Only the yaw control of the DSC is deactivated. DSC light illuminated
The ADB and DBC functions remain active. A higher slip ratio is allowed up to 42 mph for the
purpose of improving traction in slippery conditions. ASC uses different thresholds.

Long press: >2.5s All ASC, ADB, DSC, GMR (yaw control) and DBC DSC light and general
control functions are deactivated. brake warning light (yellow ABL) illuminated.
Used for service and use on dynamometers.
