Module Communications Network Ford Econoline E250

Note. The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

Multiplexing is a method of sending 2 or more signals simultaneously over a single circuit. 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 2 module communication networks which are connected to the Data Link Connector (DLC), located under the instrument panel

1. High Speed Controller Area Network (HS-CAN)
2. Medium Speed Controller Area Network (MS-CAN)

Scheme 1

Network Termination

The Controller Area Network (CAN) uses network termination 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

1. stabilizing bus voltage.
2. eliminating electrical interference.

Gateway Module

The Instrument Panel Cluster (IPC) is the gateway module, translating messages on the High Speed Controller Area Network (HS-CAN) to the Medium Speed Controller Area Network (MS-CAN) and vice versa. This allows a message to be distributed throughout both networks.

The IPC is the only module on this vehicle that has this ability.

Principles of Operation

Note. The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

Both the High Speed Controller Area Network (HS-CAN) and the Medium Speed Controller Area Network (MS-CAN) use an unshielded twisted-pair cable of data (+) and data (-) circuits.

The HS-CAN operates at a maximum data transfer speed of 500 Kbps and is designed for real time information transfer and control. The MS-CAN operates at a maximum data transfer speed of 125 Kbps for bus messages and is designed for general information transfer.

High Speed Controller Area Network (HS-CAN) Modules

The following modules are on the HS-CAN

1. ABS module (except cutaway chassis)
2. Accessory Protocol Interface Module (APIM) (if equipped)
3. Instrument Panel Cluster (IPC)
4. PCM
5. Restraints Control Module (RCM)
6. Trailer Brake Control (TBC) (if equipped)
7. Telematics module (if equipped)

Medium Speed Controller Area Network (MS-CAN) Modules

1. Audio Control Module (ACM) (if equipped)
2. APIM (if equipped)
3. Global Positioning System Module (GPSM) (if equipped)
4. IPC

Controller Area Network (CAN) Fault Tolerance

Note. The oscilloscope traces below are from the IDS oscilloscope taken using the IDS pre-configured CAN settings. The traces are for both data (+) and data (-) circuits 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.

Scheme 5

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.

Scheme 6

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.

Scheme 7

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.

Scheme 8

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.

Scheme 9

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.

Scheme 10

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.

Scheme 11

Rhythmic oscillations, inductive spikes or random interference can corrupt 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 in illustration 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 two or more messages on the same network circuits. The following chart summarizes the messages sent and received on the network.

Note. Some HS-CAN faults may result in a no-start condition.

3. Connect the scan tool to the DLC. NOTE: Make sure to use the latest scan tool software release. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM. If the Integrated Diagnostic System (IDS) does not communicate with the VCM: Check the VCM connection to the vehicle. Check the scan tool connection to the VCM. GO to «PINPOINT TEST P»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__pinpoint-test-p-no-power-to) , to diagnose No Power To The Scan Tool.
4. Establish a scan tool session. NOTE: The scan tool will first attempt to communicate with the PCM, after establishing communication with the PCM, the scan tool will then attempt to communicate with all other modules on the vehicle. If an IDS session cannot be established with the vehicle, (IDS may state "No communication can be established with the PCM"): Choose "NO" when the scan tool prompts whether or not to retry communication. Enter either a PCM part number, tear tag or calibration number to identify the vehicle and start a session (the PCM part number and 4-character tear tag are printed on the PCM label). GO to «PINPOINT TEST A»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__pinpoint-test-a-the-pcm-does) , to diagnose The PCM Does Not Respond To The Scan Tool.
5. Carry out the network test. If the network test passes, retrieve and record the continuous memory DTCs and proceed to Step 6. If the network test fails, GO to «SYMPTOM CHART»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__symptom-chart) to diagnose the failed communication network. If a module fails to communicate during the network test, GO to «SYMPTOM CHART»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__symptom-chart) .
6. Retrieve and review the DTCs. If the DTCs retrieved are related to the concern, go to «DTC CHARTS»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__dtc-charts) . Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes) prior to the network DTC diagnostics (U-codes). For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in «MULTIFUNCTION ELECTRONIC MODULES»(/ford/econoline-e250/2012-2013/remont/cruise-control-systems/#multifunction-electronic-modules) . If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(/ford/econoline-e250/2012-2013/remont/communication-devices/#module-communications-network__symptom-chart) .

DTC Charts

Note. Network DTCs (U-codes) are often a result of intermittent concerns such as faulty wiring or low battery voltage occurrences. Additionally, vehicle service procedures such as module reprogramming will often set network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to BATTERY, MOUNTING AND CABLES .

Note. Some modules on this vehicle utilize a 5-character DTC followed by a 2-character failure type code. The failure type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous Memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
