Gateway Module

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

NOTE: The GWM , communicates with the 4 controller area networks (CAN). The OBD DLC is fitted to the GWM , and is the direct interface with the scan tool.

The GWM is mounted under the driver side instrument panel. The OBD connector is fitted to the GWM . The GWM acts as a central gateway to translate messages across all 4 vehicle controller area networks (CAN), and vice versa. The GWM is the only module on this vehicle with this ability. The GWM also serves as a termination module for each of the networks to which it is connected.

The 2 module communication networks connected to the DLC are HS-CAN1 and HS-CAN2. These 2 networks communicate directly with the diagnostic scan tool. The other 2 communication networks, HS-CAN3 and MS-CAN, communicate on the network, but do not communicate directly with the diagnostic scan tool. The GWM translates the messages from these 2 networks to the HS-CAN2, which transfers the signals to the diagnostic scan tool.
