1079 - 3

Voltage on inlet air boost pressure and 
temperature sensor (F649) supply wire, pin A10, 
is too high due to:
-

short circuit to supply on wiring to pin A10 of 
the ECU or the power supply to the remote 
throttle potentiometer, pin B68, of the ECU

-

incorrect ECU (D903) power supply

Reduced engine output.
The engine does not respond to remote throttle 
operation, if applicable.

1079 - 4

Voltage on inlet air boost pressure and 
temperature sensor (F649) supply wire, pin A10, 
is too low due to:
-

short circuit to earth on wiring to pin A10 of 
the ECU or the power supply to the remote 
throttle potentiometer, pin B68, of the ECU

-

incorrect ECU (D903) power supply

-

short circuit to earth in inlet air boost 
pressure and temperature sensor (F649)

-

short circuit to earth in remote throttle 
potentiometer

Reduced engine output.
The engine does not respond to remote throttle 
operation, if applicable.

1080 - 3

Voltage on fuel rail pressure sensor (F648) 
supply wire, pin A12, is too high due to:
-

short circuit to supply on pin A12 of the ECU

-

incorrect ECU (D903) power supply

Reduced engine output.

1080 - 4

Voltage on fuel rail pressure sensor (F648) 
supply wire, pin A12, is too low due to:
-

faulty rail pressure sensor

-

short circuit to earth on pin A12 of the ECU

-

incorrect ECU (D903) power supply

Reduced engine output.

1081 - 3

Voltage on accelerator pedal (F671) power 
supply, pin B55 of the ECU, is too high due to:
-

faulty accelerator pedal position sensor

-

short circuit to supply in wiring to pin B55 of 
the ECU

-

incorrect ECU (D903) power supply

Indistinct or no response to accelerator pedal.

1081 - 4

Voltage on accelerator pedal (F671) power 
supply, pin B55 of the ECU, is too low due to:
-

faulty accelerator pedal position sensor

-

short circuit to earth in wiring to pin B55 of 
the ECU

-

incorrect ECU (D903) power supply

Indistinct or no response to accelerator pedal.

1347 - 5

Current measured in the fuel pump control 
solenoid valve (B334) circuit is too low due to:
-

interruption in wiring to pin B05 and/or pin 
B07 of the ECU

-

fuel pump control solenoid valve connector 
connected incorrectly or not at all

-

interruption in magnet coil of fuel pump 
control solenoid valve 

Irregular engine running and reduced engine 
output.
Loud combustion knocking.

1347 - 6

Current measured in the fuel pump control 
solenoid valve (B334) circuit is too high due to:
-

short circuit to earth in wiring to pin B05 and/
or pin B07 of the ECU

-

short circuit in wiring to pin B05 and/or pin 
B07 of the ECU

-

short circuit in magnet coil of fuel pump 
control solenoid valve 

-

Engine starts but will not fire.

-

Longer start time before engine fires.

-

Reduced engine output.

2. ECS-DC3 CUSTOMER PARAMETERS

2.1 INTRODUCTION

Customer parameters
Customer parameters are the settings of an 

electronic system. The customer parameters 

permit adapting control functions of a system to 

the customer's particular wishes and/or needs 

within certain limits. The customer parameters 

are stored in a list in the memory of the electronic 

unit. Customer parameters can be modified using 

the programming feature of DAVIE XD. 

Programming using DAVIE XD is only possible if 

the logged-in user has been registered as a 

"Master Technician".

Note:

Erroneous settings of customer parameters may 

affect the action of control functions to such an 

extent that they function eratically or not at all. 

After modification of the settings the (modified) 

customer parameters must be stored in the 

electronic unit using the programming function in 

the customer parameter overview.

Customer parameter names and codes
Each customer parameter in a system has its 

own name and code. The following explanation of 

the customer parameters includes only the 

codes. The availability of a customer parameter 

in a system depends on the programmed 

software in the electronic unit. The programmed 

software depends on the vehicle configuration/

identity card data.

Standard values
Standard values, options and setting ranges may 

vary according to the software variants of 

DAVIE XD and the system. This is why they have 

not been included in the following explanation of 

the customer parameters.
