Normal Operation and Fault Conditions

WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.

With the ignition ON, the VDM sends messages to the SASM over the HS-CAN 2. If the SASM does not receive these messages within a certain time frame (usually less than 1 second), the SASM sets DTCs.
