Distance Signal (Road Speed)

Up to 9/97  - This information is supplied to the IKE by the ABS/ASC+ T or DSC control module with a square-wave signal. Pulses from the left-rear wheel speed hall sensor are used to produce this dynamic digital signal. The IKE processes this for the cluster display and provides a speed signal output on the I / K-Busses.

From 9/97  - The left rear wheel speed signal is sent by the DSC module to the IKE via the CAN-Bus.
