Dynamic Digital Inputs

DYNAMIC DIGITAL INPUTS







Distance signal - This information is supplied to the IKE by the ABS/ASC+T 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.

Engine speed signal - The ID signal is produced by the DME and sent to the IKE. Excessive engine speed events are stored in the IKE and can be read out through DIS. Engine speed is transmitted over the I/K buses.

Injection Signal - The DME supplies the signal to the IKE for fuel consumption evaluation.

Dimmer signal - This is a pulse-width modulated signal from terminal 58, of the Lamp Control Module. It is used to control back lighting of instruments and the LCD and is also transmitted to the I/K buses.

Transmission Interface - This single-wire is a serial one-way interface that provides the IKE with selector lever position, driving program and the fault message. This information is also sent to other control units over the I/K buses.
