I have a Crown stock picker (SP3450H-30 2007 model) that I have been chasing a boot error shut down on for months now. The truck always recovers when re-keyed and runs for up to 150 hrs (run time) between fails. When it shuts down the only thing showing is 282 flash code on dispay and 258 flash code on SCM. Since the 2 codes are basically the modules saying they cant see/talk to each other that is the direction I have gone. Here is what has been done...
1) Dist board swapped with another truck
2) SCM swapped with another truck
3) DCM swapped with another truck
3) Main harness (dist. board to SCM) repalced new
4) All 4 mast cables replaced new

ALL connectors, plugs etc have been cleaned and proper termination checked multi times...

No fault codes logged in the fault code history.

The static/ground drag strap has been replaced also & paint removed at mounting point to be sure of good contact.

This has all been over 8 months or so. Like I said it will recover and run for 100 to 150+ run hrs between fails.

This machine is driving me to drink! Any help/ideas would be really cool.
Thanks!
