MS-CAN Network Communication Fault Chart
HS-CAN
The HS-CAN network uses an unshielded twisted pair cable of data (+) and data (-) circuits. The data (+) and the data (-) circuits are each regulated to
approximately 2.5 volts during neutral or rested network traffic. As bus 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 bus message is sent. Multiple bus messages can be
sent over the CAN circuits allowing multiple modules to communicate with each other. The HS-CAN is a high speed communication network used for
the instrument cluster, the PCM, the ABS module, the occupant classification sensor (OCS), restraint control module (RCM), the traction battery
control module (TBCM), the transmission control module (TCM), the power steering control module and the four wheel drive (4WD) control module
communications, and designed for real time information transfer and control. The HS-CAN network will not communicate while certain faults are
present, but will operate with diminished performance with other faults present.The HS-CAN bus may remain operational when 1 of the 2 termination
resistors are not present.
The HS-CAN network operates at a maximum data transfer speed of 500 Kbps and is designed for real time information transfer and control. The
network will remain operational, but at a degraded level when certain circuit faults are present.
The following fault chart describes the specific HS-CAN network failures and their resulting symptom:
