Self-Diagnosis/Electrical Test

Self-diagnosis

Function
The central component of the four-wheel drive
is the electronically-hydraulically controlled
Haldex coupling.
Advantages:
♦ stepless distribution of force between front
and rear wheels
♦ short response time of the Haldex coupling
♦ individual adaptation of the four-wheel drive
to all driving situations
Overview of control units
A distinction is made between two types of con-
trol units for four-wheel drive -J492-.
♦ Up to 09.99 none of the control units has a
diagnostic capability. On such models, per-
form the electrical test in full when dealing
with complaints ⇒ page 01-21.
♦ From 10.99 all of the control units have a
diagnostic capability. This new generation of
control units with modified software is rec-
ognizable only from the part number of the
control unit.
