DESCRIPTION AND OPERATION
Communications Network
Overview
Multiplexing is a method of sending 2 or more signals simultaneously on the same network circuits. Multiplexing is used to allow 2 or more electronic modules (nodes) to communicate simultaneously 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 3 module communication networks which are connected to the Data Link Connector (DLC), located under the instrument panel:
- High Speed Controller Area Network (HS-CAN)
- Medium Speed Controller Area Network (MS-CAN)
- Infotainment Controller Area Network (I-CAN)
System Operation

Module Network Chart
Network Termination
The Controller Area Network (CAN) uses network termination resistors to improve communication reliability. Termination modules are located at both ends of the network. As network messages are broadcast in the form of voltage signals, the network voltage signals are stabilized by the termination resistors.
Each termination module has an internal 120 ohm resistor that bridges across the positive and negative bus connection. With two 120 ohm resistors located in a parallel circuit configuration, the total network impedance, or total resistance, is 60 ohms.
Network termination improves bus message reliability by:
- stabilizing bus voltage.
- eliminating electrical interference.
Gateway Module
The Body Control Module (BCM) and Instrument Panel Cluster (IPC) are the gateway modules. The BCM translates messages on the HS-CAN to the MS-CAN and vice versa. The IPC translates messages on the HS-CAN to the I-CAN and vice versa. This allows a message to be distributed through all three networks. The BCM and IPC are the only modules on this vehicle that have this ability.
High Speed Controller Area Network (HS-CAN)
The HS-CAN operates at a maximum data transfer speed of 500 Kbps and is designed for real time powertrain information transfer and control.
Modules on the HS-CAN communicate using bussed messages. The HS-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, the HS-CAN allows sharing of information between all modules on the network.
Medium Speed Controller Area Network (MS-CAN)
The MS-CAN operates at a maximum data transfer speed of 125 Kbps and is designed for general information transfer.
Modules on the MS-CAN communicate using bussed messages. The MS-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. In addition to scan tool communication, the MS-CAN allows sharing of information between all modules on the network.
Infotainment Controller Area Network (I-CAN)
The I-CAN operates at a maximum data transfer speed of 500 Kbps and is designed for real time audio and multimedia information transfer and control.
Modules on the I-CAN communicate using bussed messages. I-CAN uses an unshielded twisted pair cable, data bus (+) and data bus (-) circuits. The I-CAN allows sharing of information between all modules on the network.
The I-CAN is connected to the DLC, but the I-CAN modules communicate with the scan tool over the HS-CAN. The IPC is used as a gateway module for the messages to transfer between the scan tool and the modules on the I-CAN.
Controller Area Network (CAN) Fault Tolerance
NOTE: The oscilloscope traces below are from the Integrated Diagnostic System (IDS) oscilloscope taken using the IDS pre-configured CAN settings. The traces are for both data (+) and data (-) taken simultaneously (2-channel) at a sample rate of 1 mega-sample per second (1MS/s) or greater.
Traces below are viewed at 500mV per division (vertical axis) and 20 microseconds (20μs) per division (horizontal axis). Readings taken with a different oscilloscope vary from those shown. Compare any suspect readings to a known good vehicle.
Normal CAN Operation
The data (+) and data (-) circuits are each regulated to approximately 2.5 volts during neutral or rested network traffic. As messages are sent on the data (+) circuit, voltage is increased by approximately 1.0 volt. Inversely, the data (-) circuit is reduced by approximately 1.0 volt when a message is sent.
Successful communication of a message can usually be identified by the slight spike at the end of a message transmission. Any signals that are significantly different than the normal CAN waveform may cause network DTCs (U-codes) to set or may cause a complete network outage.
CAN Circuits Shorted Together
In the event that the data (+) and data (-) circuits become shorted together, the signal stays at base voltage (2.5V) continuously and all communication capabilities are lost.
CAN (+) Circuit Shorted To Ground
In the event that the data (+) circuit becomes shorted to ground, both the data (+) and data (-) circuits are pulled low (0V) and all communication capabilities are lost.
CAN (-) Circuit Shorted To Ground
In the event that the data (-) circuit becomes shorted to ground, the data (-) circuit is pulled low (0V) and the data (+) circuit reaches near-normal peak voltage (3.0V) during communication but falls to 0V instead of normal base voltage (2.5V). Communication may continue but at a degraded level.
CAN (+) Circuit Shorted To Battery Voltage
In the event that the data (+) circuit becomes shorted to battery voltage, the data (+) circuit is pulled high (12V) and the data (-) circuit falls to abnormally high voltage (above 5V) during communication and reaches battery voltage (12V) for peak voltage. Communication may continue but at a degraded level.
CAN (-) Circuit Shorted To Battery Voltage
In the event that the data (-) circuit becomes shorted to battery voltage, both the data (+) and data (-) circuits are pulled high (12V) and all communication capabilities are lost.
CAN Circuit Signal Corruption
Rhythmic oscillations, inductive spikes or random interference can disrupt the network communications. The corruption signal source may be outside electrical interference such as motors or solenoids or internal interference generated from a module on the network. In some cases, an open in either the data (+) or data (-) circuit to a network module may cause the module to emit interference on the one circuit which is still connected. The trace shown is an example of a "sawtooth" pattern transmitted from a module with one open network circuit.
Other corruptions may be present when a module is intermittently powered up and down. The module on power up may initiate communication out of sync with other modules on the network causing momentary communication outages.
Controller Area Network (CAN) Multiplex Messages
Modules on the CAN utilize simultaneous communication of 2 or more messages on the same network circuits. The following chart summarizes the messages sent and received on the network.
Communication Message Chart
NOTE: This chart describes the specific HS-CAN, MS-CAN and I-CAN messages broadcast by each module, and the module(s) that receive the message.

Refer to Wiring Diagrams Cell 14, Module Communications Network for schematic and connector information.
Normal Operation and Fault Conditions
REFER to Communications Network.
PINPOINT TEST AC: NO HS-CAN COMMUNICATION, ALL MODULES ARE NOT RESPONDING
NOTE: Various modules set network DTCs during this test procedure. Clear DTCs from all modules after completing the diagnostic procedure.
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to Section 414-01.
Pinpoint Test AD: No Medium Speed Controller Area Network (MS-CAN) Communication, All Modules Are Not Responding

Pinpoint Test AF: No Power To The Scan Tool
Diagnostic Overview
Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.
Refer to Wiring Diagrams Cell 14, Module Communications Network for schematic and connector information.
Normal Operation and Fault Conditions
The scan tool is connected to the Data Link Connector (DLC) to communicate with modules on the High Speed Controller Area Network (HS-CAN) and Medium Speed Controller Area Network (MS-CAN).
A loss of ground or poor ground at the DLC may result in HS-CAN or MS-CAN faults while the scan tool is connected.
PINPOINT TEST AF: NO POWER TO THE DLC
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Section 414-01.
