1.1 Purpose of Dealer Script
The dealer script can give a diagnosis on a standalone
DVD player, no other equipment is needed to perform a
number of hardware tests to check if the DVD player is
faulty. The diagnosis is simply a "error" or "pass"
message. No indication is given of faulty hardware
modules. Only tests within the scope of the diagnostic
software will be executed hence only faults within this
scope can be detected.

need any user interaction and are meaningful on a
standalone DVD player.
The nuclei called in the dealer script are the following (the
number after each nucleus name corresponds with the

executed during the dealer script):
