Injection Signal

Up to 9/97  - The DME supplies the signal (ti) via a dedicated signal line. The IKE processes this signal for fuel consumption evaluation.

From 9/97 - The DME send the ti signal to the IKE via the CAN-Bus.

NOTE: On vehicles from 9/97 the wiring for the ti and TD signal may still be present in the wiring harness but the IKE is programmed to only accept the signals from the CAN-Bus.
