Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
With the ignition ON, the BCM sends messages to the SASM over the HS-CAN. If the SASM does not receive these messages within the specified time frame, the module sets a DTC. This can be due to a BCM failure, a circuit failure on the HS-CAN or an excessive load on the network. For information on the cruise control messages sent to the SASM by the BCM, refer the Description and Operation in the Anti-Lock Brake System (ABS) and Stability Control article.
