1997 MERCEDES-BENZ ML320 air condition

In the example:
Air pressure of the test location =955 hPa (mbar)
Altitude of the test location = 400 m
Intake air temperature of the test location =+20°C
2. Determine the performance on the output dynamometer =100 kW
3. In the altitude correction Table, the altitude value of the test location = 400 m, results in a height
correction factor of 46 hPa (mbar).
4. The air pressure of the test location minus the height correction factor results in an air pressure value (p)
of:
955 hPa (mbar) - 46 hPa (mbar) = 909 hPa (mbar)
In order to be able to insert the air pressure (p) into the Table, it must be rounded. In the example, to 910
hPa.
5. On the basis of the air pressure (p) = 910 hPa, we read a correction factor (KH) of 1.0787 off from the
performance correction Table with an intake air temperature (t) of 20°C.
6. The performance data in relation to normal operating conditions results in the following:
N
eo = Ne x KH
N
eo = 100 kW x 1.0787 = 108 kW
Output on the dynamometer: Ne = 100 kW
Air pressure value of the test location: P= 955 hPa (955 mbar)
Air-charge temperature of the test location: t =+20°C
Altitude of the test location: 400 m above sea level
Units: hPa = Hecto Pascal
1 hPa = 1 mbar
1 Pa = 0.01 mbar

Soft soldering materials
The alloy (mainly lead and tin) of the solder determines its melting point and thus the working temperature for
the soft soldering process. Additives modify the properties. Silver components improve e.g. the surface and the
joining properties.
The identification of the soft solders is according to DIN 1707.
Example:
L-Sn60PbCu2.
This solder consists of 60 % tin (Sn 60), max. 2 % copper
(Cu 2), the remainder is lead (Pb).
The melting point range is between 183°C and 190°C.
In the electrical system/electronic sector for vehicles, fast solders with a melting point range of approx. 180°C
to 200°C should used. These solders are available in the form of wires. They have flux from resins dissolved in
alcohol (e.g. colophonium) in their hollow center.
Soldering equipment
Soldering equipment with soldering tips that can reach a temperature of 250°C to 300°C are suitable for the
repairs specified by DaimlerChrysler. The aim is to use automatic temperature-regulated equipment (e.g.
soldering stations).
Preparation, general
Use suitable work clothing.
Use safety glasses.
Use any available soldering fume extractors, aeration.
Verify clamping devices and work surfaces.
Clean soldering tips with small wet sponge.
Protect surrounding working area from heat damage.
Preconditions for soldering
Soldering points must be clean, free of grease and oxides.

ACTIVE SERVICE SYSTEM (ASSYST) INFLUENCING PARAMETERS - GF00.20-P-0003-05A
The values of various influencing parameters are required by ASSYST for calculating the demand-based service
interval, and these are included in the calculation of the service interval as weighting factors . There are two
versions within ASSYST, the difference being in the oil level sensors fitted:
The familiar oil level indicator switch (S43) is fitted to engines (104, 111, 119, 120, 602.982, 604, 605,
606). In view of the fact that this is a switch, it is only possible to detect if the oil level drops below the
minimum level.
The oil sensor (oil level/temperature/quality, B40) is used on more recent engines (e.g. 112, 113, 166,
611, 668). This sensor consists of 2 capacitor systems with the engine oil as an insulator. If the water
content of the oil or the oil level changes, there is a change in the capacitance of the "capacitor".
The capacitance is thus a measure for the oil level.
In addition, the oil sensor (oil level/temperature/quality, B40) contains a temperature sensor which
detects the temperature of the engine oil.
All the signals are processed in the electronics integrated in the sensor to form a PWM (pulse width
modulated) signal, and passed to the engine control module (N3).
In addition to the weighting factors, which depend on reallife driving conditions, quality factors are also used
for calculating the demand-based service interval (remaining distance and remaining time).
Survey of ASSYST influencing parameters
Weighting factors (dependant on reallife driving conditions):
Load torque
Engine speed
Oil level
Engine oil temperature
Oil correction factor (is used as comparative value for determining oil level)
Coolant temperature
These data are supplied by the injection system control module (N3) to the service microprocessor over
the CAN.
The data relating to oil level, engine oil temperature and oil correction factor are supplied by the oil
sensor (oil level/temperature/quality, B40) through the injection system control module (N3), and are
therefore only available on engines fitted with this sensor.
Quality factors (these are factory-set to base values and can be changed with the HHT, if operating
conditions of the vehicle so necessitate; they influence the start distance):

General
The "Active service system (ASSYST)" draws the attent ion of the driver to a service which is due.
ASSYST is a demand-activated engine oil service system. In other words, in addition to the pure time and
distance criterion, various factors are taken into account for calculating the demand-oriented service intervals.
These are on the one hand quality factors which are c oded with the HHT, and on the other hand weighting
factors which take into account driving conditions and thus actual wear and tear.

The service intervals which are possible with ASSYST range
on engines with oil sensor (e.g. 112, 113, 166, 611) between 15 000 and 30 000 km,
for the new direct injection diesel engine 668 between 20 000 and 40 000 km,
for engines with oil level switch between 15 000 and 22 500 km (for engine 602.982 between 20 000 and
30 000 km).
The service interval achieved depends on the start distance and the driving conditions (cf. remaining
distance).
Start distance and remaining distance
Start distance refers to the service interval in km/miles which is the minimum distance which may be driven
until the next service. On engines with oil sensor (e.g. 112, 113, 166, 611, 668) this applies only, however, if the
specified quantity of oil has been added during the oil change.
The start distance is dependent on:
the set quality factors
(The quality factors are factory-set to a basic setting. They can be altered with the HHT, if operating
conditions so necessitate.)
The start distance is not dependent on the driving conditions (weighting of the distance driven) and on any oil
replenishments .
The standard value is normall
y 15 000 km, for the new direct injection diesel engine 668 20 000 km.
