Normal Operation And Fault Conditions

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2021 Lincoln Corsair, 2021 Ford Transit-350 HD, 2021 Ford Transit-350, 2021 Ford Transit-250, and 2021 Ford Transit-150. 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 to  Anti-Lock Brake System (ABS) and Stability Control  .
