Write Data By Identifier: Allows the diagnostic tool to write information into the ECU at an internal location specified by the ID.

Watchdog Driver: The Wdg module provides services for controlling and triggering the watchdog hardware. The trigger routine is called by the Watchdog Interface (WdgIf). For safety-related ECUs, the Wdg module must be developed according to ISO 26262.

Watchdog Interface: The module WdgIf enables uniform access to services of the Watchdog Driver (Wdg), such as mode switching and triggering. For safety-related ECUs, the WdgIf module must be developed according to ISO 26262.

Watchdog Manager: The module WdgM monitors the reliability and functional safety of the applications in an ECU. This includes monitoring for correct execution of SWCs and BSW modules and triggering of the watchdogs at the required time intervals. The WdgM module reacts to potential faulty behavior with multiple escalation stages. An important fact for safety-related functions according to ISO 26262 is the monitoring of correct flow sequences of critical tasks (logical supervision). For safety-related ECUs, the WdgM must be developed according to ISO 26262.

Wireless Ethernet Driver: The WEth driver abstracts access to the Wireless Ethernet hardware for sending and receiving data.

Wireless Ethernet Transceiver Driver: The WEthTrcv driver offers a uniform and hardware-independent interface for driving multiple transceivers of the same kind. Multiple radios with individual configurations are also supported.
