Principles of Operation
WARNINGS:
This procedure involves fuel additive
handling. Be prepared for fuel additive
spillage at all times and always observe
fuel handling precautions. Failure to follow
these instructions may result in personal
injury.
Eye, hand, ear protection and protective
clothing are required to be worn during
any general service or removal and
installation service procedure of fuel
additive system components. Failure to
follow this instruction may result in
personal injury.
In case of fuel additive fluid contact with
the skin or the eyes, flush immediately with
water for a minimum of 15 minutes and
seek prompt medical attention. Failure to
follow these instructions may result in
personal injury.
If fuel additive fluid is swallowed, call a
physician immediately. Rinse mouth
immediately with water, do not induce
vomiting. Failure to follow these
instructions may result in personal injury.
Always provide adequate ventilation when
working on the fuel additive fluid system
or related components. Failure to follow
these instructions may result in personal
injury.
Do not smoke or carry lighted tobacco or
open flame of any type when working on
or near any fuel related components.
Highly flammable vapors are always
present and may ignite. Failure to follow
these instructions may result in personal
injury.
CAUTION: Make sure the workshop area
in which the vehicle is being worked on is
as clean and as dust free as possible.
Foreign matter from working on clutches,
brakes or from machining or welding
operations can contaminate the fuel
system and may result in later malfunction. The fuel additive system is an on-board system
that allows the injection of an additive at each
refueling operation by the customer. The additive
quantity is proportional to the fuel quantity that has
been added. The fuel additive system module
controls the amount of additive fluid entering the
fuel tank at each refueling, A switch mounted on
the fuel filler flap is used to detect the start of the
refueling event and the fuel gauge that is mounted
within the fuel tank informs the fuel additive tank
module the quantity of actual fuel added.
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of leakage
and mechanical or electrical damage.

Changing the right-hand fuel pump and level
indicator module
E113328
If the right-hand fuel pump and level indicator
module needs to be changed on a vehicle with a
booster heater/additional heater, the bore for the
connection to the fuel-fired booster
heater/additional heater must be drilled.
The right-hand fuel pump and level indicator
module contains a demand-switched electric fuel
pump which drives two suction jet pumps. One of
them ensures that fuel is pumped from the left-hand
half of the tank into the right-hand half. On-demand
switching is performed by the fuel pump module.
To remove the right-hand fuel pump and level
indicator module it is necessary to detach theleft-hand fuel pump and level indicator module and
pull it out slightly so that the connecting hose can
be detached and the connector for the left-hand
fuel pump and level indicator module can be
disconnected. The left-hand fuel pump and level
indicator module can be removed without detaching
the right-hand fuel pump and level indicator
module.
The instrument cluster uses the signals from both
fuel fill level sensors to determine the fuel fill level.
The resistor tracks of the fuel fill level sensors
cannot be replaced individually.
The fuel filter is designed to last for the service life
of the vehicle and does not need to be replaced.
The right-hand fuel pump and level indicator
module contains an overpressure limiting valve.
This overpressure limiting valve ensures that the
fuel pressure between the injectors and the
right-hand fuel pump and level indicator module
does not exceed 3.3 bar after the engine is
stopped. This reduces the formation of vapor
bubbles and also prevents dripping from the
injectors.
Fuel filler pipe and tank cap
NOTE:
Any water in the filling area can cause the
mechanism to freeze at temperatures below 0 °C.
In this case the closing mechanism will not open
when the nozzle of the petrol/diesel pump is
inserted.

System Operation
Speed Control
Cruise control is integrated into PCM and
intervenes in engine management to automatically
keep to the target speed selected by the driver.
When the system is active, the vehicle can be
accelerated or decelerated without the accelerator
pedal being pressed. Cruise control is operated
using the control switch units on the steering wheel.
The PCM controls the throttle to achieve this. The
ABS module supplies the VSS signal for this.
On vehicles with automatic transmission, the TCM
receives a notification via the CAN (controller area
network) bus that cruise control is active. The TCM
then controls the transmission based on special
engine maps.
Cruise control recognizes three operating modes:
• "OFF": Control is switched off.
• "STANDBY": Control is switched on but not
active. The speed of the vehicle is not regulated
by the cruise control.
• "ACTIVE": Control is switched on and active. Cruise control adjusts the vehicle speed to the
stored or desired target speed.
Every time the engine is started, cruise control is
in the "OFF" mode. In this mode, only the "ON"
button is operable.
Cruise control is initially set to "STANDBY" mode
when the "ON" button is pressed. The green cruise
control indicator lamp in the instrument cluster
lights up. There is no target speed saved.
Cruise control can only be set to "STANDBY" mode
under the following conditions:
• Engine speed is between idle speed and maximum permissible speed. Cruise control can only be changed into "ACTIVE"
mode under the following conditions:
• 2nd - 6th gear engaged.
• Engine speed between idle speed and maximum
permissible speed.
• Vehicle speed at least 40 km/h.
Pressing the "SET+" or "SET-" button activates
cruise control ("ACTIVE" mode). The green "Cruise
control" indicator lamp in the instrument cluster
lights up. The current vehicle speed is saved as
the target.
In "ACTIVE" mode the "OFF", "SET+", "SET-" and
"RES" buttons are active. If the "RES" button is
pressed again, control is suspended. The "RES"
button has a dual function and is used to resume
and suspend the cruise control.
Tapping the "SET+" button (for less than 640 ms)
increases the target speed by 1 km/h at a time.
Holding down the "SET+" button (for longer than
640 ms) increases the target speed until the button
is released. If the button is not released, cruise
control accelerates the vehicle up to the maximum
permissible vehicle speed (200 km/h) or up to the
vehicle's maximum speed (whichever speed is
lower). Tapping the "SET-" button (for less than
640 ms) reduces the target speed by 1 km/h at a
time. When the the "SET-" button is held down, the
control reduces the target speed until the button is
released. If the "SET-" button is held down until
the minimum speed of 40 km/h is reached, cruise
control switches to "STANDBY" mode.
Cruise control is put into "STANDBY" mode when
the "RES" button is pressed. Control to the stored
target speed can be started again by pressing the
"RES" button again. If the "SET+" or "SET-" button
is pressed while the "RES" function is being
performed (control to saved target speed), cruise

The cruise control buttons are non-locking push
buttons. They are connected to the coil spring via
a hard-wired 9-pin plug connection.
The cruise control buttons operate according to
the resistance bridge circuit principle. The buttons
receive a 5 Volt reference voltage. When operated,
each button passes a particular voltage to the
GEM. The GEM measures this voltage and from
it determines which button has been pressed.
The operation of the cruise control buttons can be
checked by a simple measurement of the
resistance between pin 4 and pin 5 at the coil
spring 9-pin connector. A change of resistance
must occur when a button is pressed.

5. For vehicles with no stored fault(s), PROCEED in accordance with the Symptom Chart
according to the fault symptom.
6. Following checking or elimination of the fault(s) and after completion of operations, the fault
memories of all vehicle modules must be READ
OUT and any stored faults must be DELETED.
Refrigerant Circuit - Quick Check
WARNING: The air conditioning system is
filled with refrigerant R134a. Observe
"Health and Safety Precautions". For
further information
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging
(412-00 Climate Control System - General
Information, General Procedures).
Refrigerant circuit check
WARNING: Under certain circumstances,
refrigerant lines and A/C components may
be extremely hot or cold. Exercising care,
touch the refrigerant lines or A/C
components in order to check this. Failure
to follow these instructions may result in
personal injury.
When the A/C system is operating, the following
conditions should apply:
• The refrigerant line from the refrigerant compressor to the condenser must be hot.
• The refrigerant line from the A/C condenser to the fixed orifice tube must be warm, but not so
hot as the refrigerant line mentioned above.
• Determine the difference in temperature upstream and downstream of the A/C condenser
by measuring the temperatures at the refrigerant
lines. The temperature difference should be
more than 20° C, depending on the ambient
temperature. If the temperature difference is
less, check the condenser for contamination or
damage to the fins as well as operation of the
radiator fans.

• The refrigerant line between the fixed orificetube and the evaporator must be cold from the
point where the fixed orifice tube is installed.
Depending on the weather, the refrigerant line
may also have ice on its surface.
• The refrigerant line between the evaporator and the A/C compressor including the dehydrator
must be cold.
Evaporator outlet line temperature test
To test the power of the A/C system, the
temperature at the evaporator outlet line must be
measured. To do this, the following preconditions
must be met:
• Open all windows.
• Set the air distribution to the defrost/dashboardposition and open all the ventilation nozzles.
• DO NOT switch on recirculated air.
• Select lowest blower switch setting.
• Select lowest temperature setting.
NOTE: The temperature measurement cannot be
done with a thermometer which makes no contact.
The surface reflection from the metal line may
cause incorrect readings.
Connect the temperature sensor (Fluke 80 PK-8)
to the outlet line of the evaporator. Locate the
temperature sensor as close as possible to the
evaporator. Connect the temperature sensor to the
multimeter.
Start the engine and allow it to run at idle speed
for several minutes.
Switch on the A/C.
After three minutes, measure the surface
temperature of the evaporator outlet line.
If the temperature measured is 4° C or lower, the
A/C system is OK. If the temperature is higher, the
A/C system may be under-filled. For further
information, refer to
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging (412-00
Climate Control System - General Information,
General Procedures).
Frequent faults and their causes
If the cooling power of the A/C system is not
adequate, make certain that the temperature
control flap(s) is/are operating correctly. • No or poor cooling performance:
– Blockage or narrowing of a refrigerant line orin the dehydrator. The location of the
blockage or narrowing can easily be located
by temperature comparisons at the
refrigerant lines and the dehydrator. The
blockage or restriction is located at the point
where the temperature difference is
identified. Note: A temperature difference
in the area of the fixed orifice tube is
normal. If the location of the blockage or
narrowing is found, check the corresponding
component and renew as applicable.
• Sudden drop in cooling performance (after the air conditioning has been switched off for
approx. 5 minutes, the cooling performance
returns to normal):
– The cause is an iced-up fixed orifice tubebecause of moisture in the refrigerant circuit.
In order to ensure that moisture is completely
removed from the refrigerant circuit, the
dehydrator should be renewed and the
evacuation time should be extended to 2-3
hours. For further information
REFER to: Air Conditioning (A/C) System
Recovery, Evacuation and Charging
(412-00 Climate Control System - General
Information, General Procedures).
Sequence of A/C Request Signal
NOTE: The electronic automatic temperature
control (EATC) module is integrated into the air
conditioning control assembly.
NOTE: The generic electronic module (GEM) is
an integral part of the central junction box (CJB).
After actuating the A/C ON/OFF switch integrated
into the A/C control assembly, an A/C request
signal is sent from the A/C control assembly
(vehicles with EATC: EATC module) to the GEM.
From there, the signal is sent to the instrument
cluster via the MS-CAN bus. A gateway is installed
in the instrument cluster, which establishes the
connection between the MS-CAN bus and the
HS-CAN bus.
After the signal has been converted in the gateway,
it is relayed to the powertrain control module (PCM)
via the HS-CAN bus. Once all the required
parameters have been met, the PCM switches on
the refrigerant compressor and thus the A/C system
via the A/C clutch relay.
