tion information so it can leverage its proprietary time domain latency
algorithms to identify trouble. I know a technician who works for
Rivian who uses this tool regularly for troubleshooting.
OTHER NETWORKS
A local interconnect network( LIN) bus is a single-wire network that
typically operates at a much lower speed and has a 0-12V digital signal.
This network will have one master module and can have a maximum of
16 nodes connected. Any messages on this bus that need to be shared
with other non-LIN modules the transfer of this info will be carried
out via a gateway module. I have a video sharing how I was able to
leverage a breakout junction on a 2013 Chevrolet Volt to diagnose a
faulty module that was pulling the LIN bus down. The diagnostic steps
utilizing the oscilloscope begin here: youtu.be/YAKJsiy4rh4?t=176.

CONCLUSION
This article discussed vehicle network fault troubleshooting and
highlighted some of the causes of network communication faults,
such as poor connections, damaged wiring, and malfunctioning
control modules. We also discussed various tools and techniques
that can be used to troubleshoot and diagnose these faults, including
digital multimeters, scan tools, oscilloscopes, and CANBUS
sniffing tools. Overall, just remember the importance of following
the vehicle manufacturers' recommended procedures for scanning
the vehicle so one doesn't inadvertently inject a problem into a
vehicle during service.
