General Informtion
With the introduction of the 1994 model 3 Series (E36), BMW is pleased to announce a new Automatic Stability Control with Traction Control System (ASC+T) known as ASC+T (Teves). This system is available as optional equipment on all M50 engine equipped 1994 3 Series vehicles.The Teves ASC+T system is a further development of the Teves ABS Mark IV system. The Automatic Stability Control Plus Traction (ASC+T) system is incorporated into the Teves ABS Mark IV system with the addition of only a few additional components.
The technician is encouraged to review the Technical Reference bulletins in order to review the concepts of wheel slip, lateral locating forces, braking coefficients, and features and limitations of previous ABS, ACS, and ASC+T systems:
34 04 83 (2035) Anti lock Braking System
12 01 89 (2095) Automatic Stability Control
34 01 90 (2105) Automatic Stability Control with Traction Control System
The function of the Teves ASC+T system is similar to ASC systems installed in other BMW models, namely the control of wheel slip by providing traction control (while driving off and at slow speeds) and stability control (while driving at cruising speeds and while cornering). By controlling wheel slip, frictional contact is maximized between the tires and the road surfaces under a variety of driving conditions.
