Indirect Signals and Wiring

There is no direct connection to the OBD diagnostic connector. The ECM is connected to the ZGM (central gateway module) via the PT-CAN bus. The OBD diagnostic connector is connected to the ZGM.

The fuel pump relay is controlled by the ECM via the ZGM and ISIS (Integrated Safety and Information System) using the airbag control unit in the SBSR (right-hand side satellite B-pillar). This enables the fuel pump to be switched off in the event of an accident.

There is no direct control for the air conditioning compressor. The A/C compressor is now controlled by the IHKA control module. The IHKA signals the ECM via the PT CAN bus and the ZGM.
