Passive Open Tailgate

WARNING: This page is about a different variant/trim than selected.

Pressing the Trunk/Tailgate Lid Switch when Trunk/Tailgate is closed indicates the operator's intent to open the Trunk/Tailgate and thus triggers the system. Subsequently, the SMK ECU sends a LF-challenge to the SMART KEY FOB via the exterior bumper antenna. The SMART KEY FOB answers with a RF-response. If the received response matches the expected answer, SMK ECU sends a "Trunk/Tailgate open" message via the CAN network.
