Vehicle Communication Systems
VEHICLE COMMUNICATION SYSTEMS EXAM COVERAGE
The Vehicle Communication Systems exam evaluates understanding of
communication technologies used in modern vehicles for diagnostics,
control, and data exchange. The exam coverage includes vehicle
network fundamentals such as CAN bus, LIN, MOST, and FlexRay
systems, along with message transmission and signal routing. It also
assesses knowledge of electronic control modules (ECMs), sensor and
actuator communication, and troubleshooting network faults such as
open circuits, shorts, and signal interference.
,With the bus active and no faults present, what voltages should be
measured on CAN-C (-)?
Not Approximately 4.8V
1.3-2.3V
What vehicle architectures use a manual process in the scan tool to
program ECU PROXI configuration? Select all that apply.
What is the resistance of the terminating resistor on networks
equipped with one star connector?
60 ohms (Normal CAN Bus terminating resistance)
, What vehicle architectures use an automatic process to transfer ECU
configuration? Select all that apply.
