Information
The specified working time was determined specifically for carrying out this campaign and includes all
required preliminary and subsequent work.
The working time may differ from the working time published in the Labor Operation List in PIWIS.

Information
Information on the working time:
Generally, the working time includes all work that requires the active participation of the service technician.
This also covers all required preliminary work and subsequent work.
The working time includes the following activities during control unit programming:
•

All required steps for starting or finishing programming

•

Required interaction during a programming sequence

•

Waiting times until programming starts

•

Random check of programming status

If no further interaction by the service technician is required once control unit programming has started
because programming is performed automatically, there is no need for the service technician to remain
at the vehicle for the entire programming time.
These waiting times are not included in the working time if the total programming time is more than 15
minutes.
If programming takes up to 15 minutes, the full waiting time is included in the working time.

Scope:

Working time:
updating software of various control units
Includes:
