The sensors are connected with the TCU via the wiring
harness.
â–² WARNING: If an inspection reveals irregularities, then the
engine must not be taken in operation until the
cause is found and rectified.
The easiest way to check function of turbo control components
is by the communication program. If this program is not at your
disposal, the following static checks can be carried out.
- For verification and troubleshooting, check all connections
for passage and physical damage. See Fig. 76-31.
- Verify that all plug connections fit tightly.
â– CAUTION: In the event of physical damage or incorrect
operation, replace part without delay. Repair
on your own authority is not permitted.
â—† NOTE: Fig. 76-31 contains a lot of information. Be-
sides the wiring designations, plug allocation,
cable length, the polarity of the voltage supply
to the single components are also stated.
If the wiring harness is replaced, the throttle valve position
must be recalibrated (see 76-00-00 sec. 3.1.1.7) and the
turbocharger control checked in accordance with 76-00-00
sec. 4
If this aid is not at your disposal, an engine test run has to be
performed. See corresponding Maintenance Manual (Line
Maintenance) for the respective engine type 914 Series.
