Odometer Does Not Work

While moving, the odometer does not work, or operates erratically. The speed signal comes from the Anti-Lock Brake System (ABS) Module to the Body Control Module (BCM) via the CAN-C network and is then made available to Instrument Panel Cluster (IPC) via the CAN-B network from the BCM gateway.
