Figure 4: Electrical pump connection with adapter lines for compact
connector - (3) and Jetronic connection (2)
Procedure:
– Connect the connecting line 1 684 462 511 (1) of the CRE 800
control device to adapter lines (2 and 3) on the solenoid valves
DMV1, DMV2 and the rpm sensor (speed sensor) of the
common-rail pump.
i To connect the connector cable (see Fig. 5, Pos. 1) the
multipurpose adapter lines with flat-type connector 1 684
460 256 (see Fig. 5, Pos. 2) can also be used. These are
available in the delivery specification of the CRS 845 tester
set.
The polarity of the electrical terminal of the solenoid valves
DMV1 and DMV2 is optional. For this reason, it is not
necessary to observe the polarity for adaptation with the
multipurpose adapter lines 1 684 460 256.
! Do not use the multipurpose adapter line with flat-type
connector 1 684 460 256 for adaptation on the rpm sensor
(speed sensor) of the CP 2 common-rail pump.
! Connector cable 1 684 462 499 may not be used for testing
CP 2 common-rail pumps.
