E46 Dynamic Stability Control Systems

Coding

Coding must be performed after replace-

ment of the DSC III control module or the

steering angle sensor. ZCS coding is found

in the Coding and Programming selection

from the start screen or when pressing the

Change button. Follow on-screen instruc-

tions for initialization of components after

completing the coding process.

Adjustment Functions

Adjustment (initialization) is required when:

• Replacing the DSC III Control Unit.

• Replacing/Re-coding the Steering Angle Sensor.

• Replacing one or both Brake Pressure Sensors.

• Replacing Lateral Acceleration Sensor.

Steering Angle Sensor

The steering angle sensor requires an offset adjustment after the sensor has been replaced,

coded or after repairs to the steering or suspension system. The offset adjustment informs

the steering angle sensor processor of the straight ahead position of the front wheels.

The adjustment is performed by completing the Test Module found in Service Functions.

Once the adjustment is complete the sensor sends an identification number over the CAN

bus to the DSC control unit. The ID provides confirmation that the steering angle sensor is

coded and has successfully completed the adjustment procedure.
