In order to minimise module variations, different equipment levels and functionalities are incorporated in the same module. Following a replacement this module needs to be programmed or configured with the aid of WDS. All of the required data (software) are loaded by the WDS into the module. In the process it is for example also possible to replace older software versions with a more current version. If the required data are already present in the module then it needs to be configured. In this process certain parameters are set, and inputs and outputs are enabled or disabled. As a general rule, these parameters should be read out with the aid of WDS from the module which is to be replaced and then transferred to the new module. If this is not possible (e.g. because the old module will no longer react), then the vehicle-specific data will need to be entered manually via a selection list in WDS or via a code which can be obtained from the Technical Hotline. REFER TO WDS for further information. | | | -
The following need(s) to be programmed following a replacement: - Powertrain control module (PCM)
| | | -
The following need(s) to be configured following a replacement: - Restraint control module (RCM)
- Generic electronic module (GEM)

In order to adjust certain settings and function values, various modules will need to be initialised after the replacement or after disconnecting the power supply. Here, the input signals received by a module are for example allocated to a particular operating state. The initialisation process takes place on a system-specific basis. For further information REFER to the relevant section. The following need(s) to be initialised following a replacement: - Passive anti-theft system (PATS)
- Steering shaft rotational angle sensor (only on vehicles with ESP)
- Xenon headlamps (headlamp levelling)
- Electric window lifter modules
