2. ECAS-2 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.
