Basic setting (scan tool
function 04)
Initiating "Basic Setting" function 04 does the
following for ESP:

The steering angle sensor -G85- is zeroed
using display group 001 page 01
-243

Before you can zero the sensor, you must have
successfully carried out the "Login Procedure"
function 11 using the VAG1551/1552 scan tool
and the ABS control module -J104- must be
coded page 01
-234
.

The hydraulic pump for traction control -
V156- is activated using display group 002
Activation of the hydraulic pump for traction
control -V156- does not require any preparations.
It is used to bleed the hydraulic system page

-248
.

The ESP driving test is activated using
display group 003
The ESP driving test is used to test the
