Hydrogen fuel cell bus
Hydrogen bus network fault, found on a lunch break
By Sebastian Rivera
The short answer
The network fault on this hydrogen bus came from the gateway, which had the wrong software installed. Sebastian isolated the failing network and flagged the gateway in about 30 minutes, over a lunch break during a training visit.

What this means for your team
Not every network fault is wiring or hardware. When a gateway sits between networks, its configuration and software version belong on the checklist.
