CAN comm System
NETWORKING: CAN COMMUNICATION SYSTEM: Open in One Side of CAN Branch Line
Open in One Side of CAN Branch Line
DESCRIPTION
If some ECUs and sensors are not displayed on the "CAN Bus Check" screen of the Techstream and some ECUs and sensors repeatedly appear and
disappear from the screen when the CAN main bus wires are normal (there is no open, short, short to B+ or short to GND in the main bus wires), there
may be an open circuit in either of the CAN branch wires.
HINT: If some ECUs and sensors repeatedly appear and disappear from the "CAN Bus Check" screen, communication between the normal
ECUs (sensors) and the Techstream may be affected by the incomplete signals that are output from the ECU that has an open circuit in either
of its CAN branch wires. In this case, the CAN branch wires for the ECUs and sensors that repeatedly appear and disappear from the screen
are normal and the ECU that is not displayed on the screen may be the main cause of the problem (this ECU may have an open circuit in either
of its CAN branch wires).
