Escape 4WD V6-3.0L (2008)
Gateway Module
The instrument cluster is the gateway module, translating HS-CAN to MS-CAN and vice versa. This information allows a message to be distributed
throughout both networks. The instrument cluster is the only module on this vehicle that has this ability.
COMMUNICATIONS NETWORK - HYBRID
Vehicle communication utilizes both International Standards Organization (ISO) 9141 and controller area network (CAN) communications. ISO 9141 is
used for diagnostic use only while CAN allows many modules to communicate with each other on a common network. CAN in-vehicle networking is a
method for transferring data among distributed electronic modules via a serial data bus.
Without serial networking, intermodule communication requires dedicated, point to point wiring resulting in bulky, expensive, complex, and difficult to
install wiring harnesses. Applying a serial data network reduces the number of wires, combining the signals on a single network. Information is sent to
the individual control modules that control each function.
The vehicle has 3 module communication networks:
-
ISO 9141
-
Medium speed (MS) CAN
-
High speed (HS) CAN
All 3 networks are connected to the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one scan tool to be
able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering
column and the audio unit.
