Ford Fiesta: Module Communications Network / Communications Network - Overview. Description and Operation
Overview
Multiplexing is a method of sending 2 or more signals simultaneously over a single circuit. Multiplexing allows 2 or more electronic modules (nodes) to communicate over a twisted wire pair [data (+) and data (-)] network. The information or messages that can be communicated on these wires consists of commands, status or data. The advantage of using multiplexing is to reduce the weight of the vehicle by reducing the number of redundant components and electrical wiring.
The vehicle has 2 module communication networks connected to the DLC , located under the instrument panel. The communication networks are:
- High Speed Controller Area Network (HS-CAN)
- Medium Speed Controller Area Network (MS-CAN)

Wheels and Tires. Diagnosis and Testing
Preliminary Inspection
Verify the customer concern by carrying out a road test on a smooth road. If any vibrations are apparent, Refer to the Symptom Chart: NVH.To maximize tire performance, inspect for signs of incorrect inflation and uneven wear, which may indicate a need for balancing, rotation or front suspension alignment.
Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear.
