conjunction with engine management
controls to control wheel spin and
maintain vehicle stability while braking.
Added midway through the 1999 model
year was Dynamic Stability Control
(DSC). This system uses ASC
technology, but implements wheel
speed modulation throughout all
stages of driving. DSC is able to
reduce understeer by applying differing
amounts of braking force to each
wheel, as well as overriding the engine
management system during hard
cornering.
A summary of distinguishing
characteristics of the various systems is
shown in Table a. E46 Electronic
braking and stability control
For ABS system and component
descriptions, see
Steering and Brakes-General.
WARNING!
A car with electronic stability control
is still subject to normal physical
laws. Avoid excessive speeds for the
road conditions encountered.
