DTCs with description ?Brake control module - no signal/communication? are present in several control units. DTCs are stored in the ABS control module. This condition does not result in any drivability concerns. The steering system is fully connected. The insulation for the ABS wheel speed sensor is damaged in production. Over time, this can lead to corrosion on the wires and restricted functions with the ABS control module. Only the wires in the left bulkhead grommet are affected.
