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 ABS module over the HS-CAN2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets DTCs. For information on the messages sent to the ABS module by the VDM, refer to the Network Message Chart in  DESCRIPTION AND OPERATION  .
