Self-diagnosis

In order to carry out a complete self-diagnosis of the
on board supply control unit, the use of the equipment
VAS 5051B o VAS 5052
Despite the fact that the Gateway is integrated in the
new on board supply control unit J519, both
components possess two different address codes.
These are:
- 09. On board supply control unit.
- 19. Gateway.
The address code 09 houses all the functions referring
to the convenience on board network control unit.
9.2.

On board network

In the address code 09 a drop down menu opens where it is possible to select the option "J519 on
board supply control unit, functions". Here we find, among others, the following functions:

- Coding.

- Adaptation
- Read measured value blocks.
On the following pages of this didactic book these functions are detailed one-by-one.
9.2.1. Coding
The on board supply control unit incorporates the long codification due to the large quantity
of functions that can be configured through codification. In this manner, the code itself is a
programme matrix composed of 27 bytes, and in addition, each of the bits that compose it (1 or 0) is
assigned to equipment or a function.
The coding is carried out whenever the unit is replaced. Before removing the unit, note down the
code to re-enter again in the new unit.
With every SEAT Sport vehicle delivery a module coding sheet is provided. It is also possible to note
down the coding by consulting the vehicle diagnostic system using the tool VAS 5052

with the name of each value, there is a short
explanation of its meaning.
