Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2017 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
With the ignition ON, the FCIM sends messages to the ABS module through the GWM over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame (usually less than 1 second), the module sets DTCs. For information on the messages sent to the ABS module by the FCIM, refer to Anti-Lock Brake System (ABS) And Stability Control .
