Power-Up Sequence Test
Overview
The failure during the power-up self-check indicates a system
failure.
Detection
The power-up self-check is performed automatically each time the
key is turned on. Turn the key on and watch the Operator Display
Unit (ODU). If lights on the ODU remain on after 15 seconds, or
never come on, the self-check has failed.
Fallback
If self-check fails, the product can not perform any operations.
