Note
Before deleting any adaption values, always make an assess‐
♦
ment and keep a record of the existing adaption values. Pre‐
vious adaption values can be an invaluable aid in establishing
the condition of the individual clutches and determining how
to proceed. It will be easier to establish the cause of the com‐
plaint if proper records of the adaption values are kept.
After deleting the adaption values, an adaption drive must be
♦
performed using the "Guided Functions" or "Guided Fault
Finding". If the adaption drive is not possible, for whatever
reason, an extensive road test must be performed. The con‐
ditions for the adaption should be met as far as possible, and
the quality of every gear shift should be assessed. If certain
gear shifts come to notice, the relevant selector elements can
be adapted individually.
General adaption conditions
Various driving modes and operating conditions are required to
prevail, depending on the type of adaption and which selector el‐
ement is to be adapted. Consequently, "adaption conditions" are
defined for each adaption process.
An adaption can be performed only if the defined adaption con‐
ditions have been met.
The criteria below apply during the adaption:
♦ The ATF temperature must be within a defined range.
♦ Defined gear or gear shift.
♦ The engine load must be within a defined range. A very low
engine load or a light throttle application is usually required.
♦ No fault memory entries in the gearbox control unit.
♦ A particular driving condition must prevail (e.g. throttle applied
or overrun mode, constant driving mode, vehicle stopped with
engine idling, etc.).
♦ Good road conditions, best possible road surface, no steep
uphill or downhill gradients, flat stretch of road.
