Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2019 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
With the ignition ON, the SASM sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC.
