33025 is generally a nuisance code or a false lead. The description is VSM to display but that doesn't mean there was an actual problem with the CAN wiring. What usually happens is the Hilo shuts down for some other reason and the 33025 is a byproduct of the shutdown. By all means check connections and CAN wiring. I suggest removing the display and doing a resistance test from the face of the display connector while moving the harness at various places. But if you have telemetry with timeouts set, that code can also be a byproduct of the telemetry system. DO NOT jam your probes into the connector sockets. Keep some wires around with the matching terminal ends to plug into the display connector so you can do a hands free resistance test. The number of techs I work with that make more problems by jamming their leads where they don't belong is ridiculous. Don't be that guy!
