66-16

The current measured by the drawn vehicle
control valve (B308) magnet coil via pins B10 and
B11 of the ECU is incorrect due to:
-

copper short circuit in the magnet coil

-

short circuit or contact resistance between
pins B10 and B11 of the EBS unit

-

EBS pressure control on drawn vehicle
deactivated

66-55

Drawn vehicle control valve (B308) output
pressure measured on pin B14 of the ECU is
incorrect in relation to the current through the
magnet coil due to:
-

defective pressure sensor

-

too low a supply pressure

-

EBS pressure control on drawn vehicle
deactivated

67-42

Pressure sensor fault in drawn vehicle control
valve (B308) due to:
-

short circuit to supply on pin B14 of the EBS
unit

-

interruption on pin D3 of the EBS unit

-

short circuit to supply on pin D3 of the EBS
unit

-

Open circuit in EBS pressure control, drawn
vehicle

67-43

With a nonactivated drawn vehicle control valve,
drawn vehicle control valve (B308) pressure
sensor output signal on pin B14 of the EBS unit is
too low or too high due to:
-

defective pressure sensor

-

no or too low a supply voltage to pressure
sensor

-

Open circuit in EBS pressure control, drawn
vehicle

67-51

With a non-activated drawn vehicle control valve
and a speed >30 km/hour, drawn vehicle control
valve (B308) pressure sensor output signal on pin
B14 of the EBS unit is too low or too high due to:
-

defective pressure sensor

-

Open circuit in EBS pressure control, drawn
vehicle

68-25

Permanent actuation of the drawn vehicle control
valve (B308) due to:
-

short circuit to supply on one side and short
circuit to earth on the other side

-

Brake remains applied to drawn vehicle

68-32

Short circuit to earth on pin B10 of the EBS unit,
drawn vehicle control valve (B308)

-

EBS pressure control on drawn vehicle
deactivated

68-33

Short circuit to supply on pin B10 of the EBS unit,
drawn vehicle control valve (B308)

-

EBS pressure control on drawn vehicle
deactivated

68-34

Short circuit to earth on pin B11 of the EBS unit,
drawn vehicle control valve (B308)

-

EBS pressure control on drawn vehicle
deactivated

68-35

Short circuit to supply on pin B11 of the EBS unit,
drawn vehicle control valve (B308)

-

EBS pressure control on drawn vehicle
deactivated

68-36

Interruption on pin B10 and/or B11 of the EBS
unit, drawn vehicle control valve (B308)

-

EBS pressure control on drawn vehicle
deactivated

73-15

If a drawn vehicle with EBS sends a CAN
message to the ECU of the prime mover,
indicating that the "serious drawn vehicle failure"
needs to be activated on DIP, this fault code will
be stored in the prime mover ECU.

2. EBS 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.
