Principles of Operation

PRINCIPLES OF OPERATION

Communications Network
The controller area network (CAN) is a high speed communications network used for powertrain communication. The CAN remains operational even with the severing of one of the CAN circuits. Communications also continue if one of the CAN circuits is shorted to ground or voltage, or if some but not all termination resistors are lost.

The standard corporate protocol (SCP) communications network remains operational even with the severing of one of the SCP communications network circuits. Communication continue if one of the SCP communications network circuits is shorted to ground or voltage, or if some but not all termination resistors are lost.

The international standard organizations (ISO) 9141 communications network does not function if the single ISO 9141 communications network circuit is shorted to ground or voltage.
