Service - Volkswagen Caddy 2004 Self-Study Programme

Service

Diagnosis
The VAS 5051 vehicle diagnosis, measuring and information system and the VAS 5052 vehicle diagnosis
and service information system are available for the 2004 Caddy.
The VAS 5051 vehicle diagnosis, measuring and
information system has the familiar operating
modes:
– Guided fault finding
– Vehicle self-diagnosis
– OBD (on-board diagnosis)
– Measuring technology
The "Guided Fault Finding" operating mode
checks all control units installed in the vehicle for
fault entries and automatically compiles a system
test plan from the results.
In conjunction with ELSA information, for
example, the circuit diagrams or repair guides,
this mode guides you directly to the cause of the
fault.
In addition, you also have the option of compi-
ling your own test plan.
The function and component selection records
the tests you select in the test plan. You can then
work through the tests in any order during the
diagnosis procedure.
The "Vehicle self-diagnosis" mode can still be
used, but there is no further ELSA information
available.
For more detailed information on the procedure and guided fault finding, please refer to
chapter 7 of the VAS 5051 operating manual.

VAS 5051
The "Guided Functions" mode is new. In this
way, without a complete vehicle system test, you
can quickly access general service functions, for
example, adapting vehicle keys.
It is used from the basis CD V06.00.00 and the
Volkswagen brand CD V06.42.00.
The VAS 5052 also has the
"Guided Fault Finding" and
"Guided Functions" operating
modes.
