Basic Setting (scan tool function 04)


Notes:

Basic setting is carried out with engine
running.
The OBD II engine control module shows the
"Readiness Code" in display group 29. The
readiness code is reset when the engine control
module power is off and each time the DTC
memory is erased. In order to regenerate the
readiness code it is necessary to take a trip in
"mixed city and highway" driving-approx. 1-1/2
to 5 minute drive at 80-100 km/h (50-63 mph)
with manual transmission in 4th or 5th gear,
preferably 4th gear, or automatic transmission
selector lever in "D" position.
When the "Basic Setting" function 04 is initiated
with the VAG 1551 scan tool, the learning
values are relearned in systems capable of
learning. Learning is prohibited, as soon as a
malfunction is stored in the DTC memory that
relates to a system capable of learning (not with
sporadic malfunctions).
All learning values are erased by disconnecting
the connector from the Engine Control Module
(ECM). After that, uneven idle can occur briefly.
In this case, let engine run in idle for a few
