Removal and Installation of DSV Control Module - ra07016028823x(8823)
Engine 603.971 in Model 140
Operation no. of operation texts and work units or standard texts and flat rates: 07-8823
| Vehicle identification number (VIN) | read with HHT from DSV control module (N3/13) (see menu prompting in HHT, section diesel engine, "DSV" system, version coding).
NOTE:
The DSV control module (N3/13) and the RCL control module are assigned by means of an identification. This identification cannot be erased (see HHT actual values "drive authorization system" menu point 3 identification). It is therefore not
possible to replace the DSV control module (N3/13) or the RCL control module with parts from another car as a check.
|
| DSV control module | remove, install; chisel securing bolt loose for this purpose (sheer bolt NP part no. 601 990 07 63).
NOTE:
Before first starting, the identification of the DSV control module (N3 /13) with the RCL module must be started with the HHT. If it is necessary to perform adjustment work on the injection pump (pump removed), the DSV control module (N3 /13) must be unbolted. If a new DSV control module (N3 /13)is installed for test purposes, it is essential to identify but not to interlock the control module. If the DSV control module (N3 /13) does not remain in the car, the identification is retained until the data are overridden during the next identification process. This process can be repeated as often as desired until final interlocking is performed. If a control module is not interlocked, not more than 40 starts or ignition ON/OFF may be performed otherwise the control modules will then be permanently interlocked . |
