Suspension, Steering and Brakes - ~enerail 
The main components  of the  system  are the wheel speed 
(pulse) sensors, the 
ABSIASC or ABSIDSC control  module, 
and the hydraulic control unit. 
Traction control also comes into operation during  decelera- 
tion. Decelerating on  snowy or icy road surfaces  can lead to 
rear  wheel slip.  If a  rear  wheel starts  to drag  or lock  up, the 
ASC  system can limit the problem  by adjusting  throttle, fuel 
injection and ignition  timing.

Dynamic Stability Control (DSC) 
Dynamic Stability Control (DSC) utilizes  many principles and 
components  of the  ASC  traction control  system. DSC is ac- 
tive throughoutthe driving range, unlike  ASC which  is only  ac- 
tive during acceleration and braking.  DSC helps stabilize  the 
vehicle  in cornering and avoidance maneuvers  by adjusting 
engine  controls such  as throttle, ignition, fuel injection and the 
application  of...

I Front Suspension 
This repair group  covers the repair  and replacement  of com- 
ponents that make up  the front suspension  of E39  cars. 
Two  different types  of steering systems  are used  in the  E39 
series.  6-cylinder 
(5251,5281 and 530i) models  are equipped 
with a  rack and pinion  type steering system mounted  to an 
aluminum  subframe. 
V-8 (540i) models use a steering gear- 
box  type  system mounted  to a steel  subframe.
