Pinpoint Test An : The Gateway Module (GWM) Does Not Respond To The Diagnostic Scan Tool: Notes

WARNING: This page is about a different car, the 2016 Lincoln MKZ. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Module Communications Network for schematic and connector information.

Normal Operation and Fault Conditions 

The GWM communicates with the diagnostic scan tool through the HS-CAN1 and HS-CAN2. The GWM operates as a gateway for communication between the modules on HS-CAN1, HS-CAN2, HS-CAN3 and MS-CAN.

Visual Inspection and Diagnostic Pre-checks 

Verify BCM fuses 13 (7.5A) and 15 (10A) are OK.
