Functions for "ignition ON":

 Engine control is achieved over the circuit 87 relay, engine (for model 211) or over the CDI relay (for model 220) by means of a voltage from "circuit 87"

 For fuel predelivery, the fuel pump is actuated for
approx. 30 seconds (only for first "Ignition ON")

 To obtain a lamp check in the preglow indicator lamp and the engine diagnosis indicator lamp (or for model 211  the CHECK ENGINE indicator lamp) are actuated the instrument cluster for about 1 second

 Preglowing through actuation of glow plugs over the glow output stage (or for model 211  over the glow time output stage)

 Data exchange via the CAN databus (circuit 50 signal).

 The fault memory can be read out and cleared via the data link connector .

 Corrective programming can be carried out using STAR DIAGNOSIS via the diagnosis data link connector
