Check Bus 5 Line for Short to GND [12/2021 - 10/2022]: Description

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

There may be a short circuit between one of the CAN bus wires and GND when there is no resistance between terminal 15 (CA5H) of the central gateway ECU (network gateway ECU) and terminal 4 (CG) of the DLC3, or terminal 16 (CA5L) of the central gateway ECU (network gateway ECU) and terminal 4 (CG) of the DLC3.
